Electricity & DNA Connections

discussion- An enormous amount of electricity is created at power-generating stations and sent across the country through wires that carry high voltages. Appliances, power lines, airport and military radars, substations, transformers, computers, and other equipment that carries or uses electricity all generate electromagnetic fields.

Many questions have been raised about how electromagnetic fields affect our bodies. Do they pose a public health risk? Perform an Internet search to find information about the effects of electromagnetic fields on public health. Then, discuss the pros and cons of using equipment that produces an electromagnetic field.

Here is one authoritative source to get you started: electromagnetic fields and public health.

Double Helix Structure of DNA

This task connects the physics of electrostatics with molecular biology. Molecular biology is the study of the structure and function of the cell at the molecular level. DNA’s double helix structure consists of two strands held together by electrostatic forces. Do online research on electrostatics and molecular biology, and then answer the following questions. Here are two sources to start with:

Part A Electricity & DNA Connections

Electric Field of Dreams

In this activity, you will explore the relationship between the strength and direction of the electric field lines to the type of charge on a particle and its magnitude. You will also explore the interactions between two or more charged particles and observe their movement. To begin your activity, open the simulation: Electric Field of Dreams. ‪‪Electric field of dreams‬ 1.0.0-dev.10‬

Directions:
At any time you may

click the Reset All button to reset all the settings;
click the Play/Pause button to pause or resume the motion; or
pause the motion and then click the Step button to observe the motion step-by-step.

Part A

To begin, click the Add button to add one object to the system. Observe the electric field around this charged object. You may move the object around the field by dragging it with your cursor. While the arrows indicate the direction of the electric field around the charge, the length of the arrows indicates the field strength. Based on your observations of the field, what is the charge on this object? Give your reasoning.

15pxSpace used(includes formatting): 0 / 30000

Part B

Set the charged object in motion by dragging it and releasing it. What do you observe about the behavior of the field lines in the vicinity of the object?

15pxSpace used(includes formatting): 0 / 30000

Part C

Add another charged object to the electric field by clicking the Add button again. What is the charge of this new object? Give your reasoning. What do you observe about the behavior of both the objects as well as the field lines in the vicinity of both the objects?

Electric Field Hockey ‪‪Electric field hockey‬ 1.0.0-dev.10‬

In this activity, you will again explore the relationship between an electric field and charged particles in the field, but this time you’ll have a gaming challenge. To begin, open Electric Field Hockey.

Directions:
On the control bar, make sure that the Puck is Positive and the Field boxes are checked. Also, make sure that the Practice option is selected.

Your aim is to score goals by manipulating the black puck (test charge) into the blue-colored bracket (goal) on the right. Think smart and place positive source charges (red) and negative source charges (blue) in such a way that the black puck moves into the goal.

Note that when you place a red, positive source charge in the hockey field, a red arrow appears on the black puck (test charge) showing the force the positive charge exerts on the puck. Similarly, when you place a blue, negative source charge in the hockey field, a blue arrow appears on the black puck (test charge) showing the force the negative charge exerts on the puck.

Part A Electricity & DNA Connections

Place a red charge in the hockey field and click Start. In which direction do electric field lines point? In which direction does the black puck move? What conclusion do you draw from this movement?

15pxSpace used(includes formatting): 0 / 30000

Part B

Click Reset and then click Clear. Now, place a blue charge in the hockey field and click Start. In which direction do electric field lines point? In which direction does the black puck move? What conclusion do you draw from this movement?

15pxSpace used(includes formatting): 0 / 30000

Part C

Manipulate the mass of the puck by dragging the Mass bar to the right for increasing the mass and to the left for decreasing it. What changes do you see in the speed of the puck? Which principle works behind this change?

15pxSpace used(includes formatting): 0 / 30000

Part D

In the same situation, what do you observe about the relationship between the speed of the black puck and its distance from the blue charge?

15pxSpace used(includes formatting): 0 / 30000

Part E

You can make the puck travel in complex ways by placing a set of charges around on the field. So, here’s your game challenge: Arrange source charges around to propel the puck from its starting position into the goal. That’s pretty easy for a straight shot; you just put a negative charge behind the goal. But what if there are barriers in the way? That’s a real test of your physics understanding, including Newton’s laws of motion and electrostatic forces. Game’s on!

On the control bar, check the Trace, Field, and Anti-alias boxes. The game has three Difficulty levels. Start with Difficulty level one and arrange source charges to get the puck into the goal. Once you’ve made a score at any level, increase the Difficulty level. Take a screen capture of two of your most difficult goals and paste them here. At least one of these should be at Difficulty level 2 or 3.

(Note: On a Windows computer, you can use the key combination Alt-Print Screen to copy the currently-active window to your clipboard. When you capture an image of this simulation window, paste the image into an image-processing program such as Paint, and save the image as a file. Then use the Insert Image button to insert the file into the response area.)

Home Electricity Use & Savings

By Academic Wizard Blog

Home Electricity Use & Savings

Discussion- It’s possible to save a great deal of electrical energy (and money and natural resources) with some simple changes in household electrical use. The trouble is that most of these changes mean either changing behavior or spending money. Do an Internet search and review a few ways to save electrical energy. Discuss at least one change that you think would be reasonable and worthwhile to do in your own home in the next year. Provide your rationale.

Home Energy Use

In this activity, you are going to perform an experiment to track the amount of power you and your family use, then look at some basic patterns in that usage. (NOTE: If you live in an apartment or home in which you do not have access to the electrical meter, consult with your instructor about alternative arrangements, like teaming with a classmate to gather this data.)

This experiment is going to span the course of a full week and require 12 meter readings. It really involves two separate experiments:

tracking daily energy use for a week to compare any usage variations from day to day
comparing a single high-usage time period of a few hours with a single low-usage time period of a few hours to help you identify the extremes in your household electrical use

You can easily do both experiments during the same time period. This approach would be the easiest and fastest way to proceed. Read the instructions for both Part A and Part B if you wish to do both experiments at the same time.

To begin, you’ll need to find your electric meter, which could be inside or outside of your home. Many electric meters these days are digital and pretty easy to read, but if you have an older “dial-type” meter, go to this electric meter reading guide to learn about how to read and understand it.

For each of the two experiments below, you will first record three simple pieces of data in a table:

1) day and date, 2) time, and 3) the kWh reading from the meter.

Then record the results of three simple calculations:

kWh used: Calculate kWh used since the last reading (subtraction).
Hours elapsed: Calculate the number of hours since the last reading (subtraction rounded to a whole number).
Average kW used: (kWh used)/(hours elapsed). If this number turns out to be 0.36, for example, it means that your average household power usage for the time period was about 360 watts, the equivalent of running six 60-watt bulbs for that whole time period.

Part A Home Electricity Use & Savings

Daily Electrical Usage: Data Collection

Pick a convenient time of day to take readings from your electric meter. You’ll need readings roughly a day apart, but if they differ by only an hour or two, that should be fine. Pick a consistent time you’ll remember, though, such as after getting home for the day. You need to start by doing an initial meter reading, then follow up with a reading every day for the next 7 days. You’ll do 8 readings in all.

Record your readings in the tables below. In addition to the data fields described above, there is a lot of room for usage notes. Record anything that might have substantially affected the electrical usage since your previous reading. This might include the amount of time people were around and awake at home, use of specific devices such as an air conditioner, clothes dryer, TV, or lighting.

Part B

Usage Extremes: Data Collection

For this experiment, you’ll measure electrical usage during a time period when you expect to have very light electrical usage (for instance, while you’re asleep at night or during the day when no one is at home). Likewise you’ll measure electrical usage during a time period when you expect to have heavier than average electrical usage. This time period might be in the evening, when lights and other appliances are on. Both of these time periods should be at least 4 hours long, to increase the accuracy of your results.

Record your results in the tables below for each situation. For each time period, you’ll need to take an initial and a final reading.

Part C

Let’s start the analysis by looking at your “extreme usage” cases. Compare the two cases in detail—low usage period versus high usage period. Discuss differences between the two as well as any surprises. Things you should cover in your discussion: How much difference was there in average power usage (avg. kW) between the low-usage and high-usage time periods? What might have been running during the low-usage period that used energy? Identify likely “stealth” energy users that you could not turn off during the low-usage period. What do you suppose contributed most to the usage during the high-usage period?

15pxSpace used(includes formatting): 0 / 30000

Part D

Having looked at your “extreme usage” cases, analyze your day-to-day usage. Discuss in detail. Specifically, compare higher usage days to lower usage days. Were there significant variations? Do your conclusions regarding the “extreme” cases help to explain any daily variations? What were the surprises or new insights you had in reviewing this day-to-day usage record?

15pxSpace used(includes formatting): 0 / 30000

Part E

It is possible to save a great deal of electrical energy (and money and natural resources) with some simple changes. You’re probably familiar with what some of those changes are and are now more attuned to your own electrical usage. The trouble is, most of these changes either mean changing behavior or spending money. Search the Web for a few ways to save electrical energy. Record them below and categorize them, if possible, as “change behavior” or “spend money.” You might want to consider adding a “neither” category. There are a few things that don’t really require much change or money at all. Include your sources in your answer.

15pxSpace used(includes formatting): 0 / 30000

Part F

Based on what you’ve learned from your household energy investigation, which of these methods seems reasonable to do in your own home this year? (Do you plan to do it?) Provide your rationale.

Electrical Safety Devices

Perform an Internet search to learn about grounding wires, fuses, and circuit breakers. Specifically,

describe how each device works; and
relate its function to what you’ve learned in this unit about electric current, voltage and resistance.

Electromagnetism & Applications

By Academic Wizard Blog

Electromagnetism & Applications

discussion- Research and discuss the aurora borealis in terms of electric charges, magnetic fields, and forces. Which times of the year are best for seeing the northern lights, and where are the best places to view them? Explain your answers. Also identify links to good images. If you’ve ever seen the aurora borealis, describe your experience and note the time and place that you saw it.

Faraday’s Law

Electric generators use the properties of electromagnetism to transform kinetic energy into electrical energy. Many electric generators work by spinning a permanent magnet near coils of wire. Experiment with this simulation of electricity generation to visualize how this process works. Once the simulation opens, try moving the permanent magnet around to see what happens. Also rapidly switch the polarity of the magnet by repeatedly clicking on the magnet icon at the bottom of the page, and observe the effect.

Part A

Try moving the magnet in the different ways described in the table below,. Record your observations in the second column of the table.

Motion Electromagnetism & Applications Observations

Move the magnet straight through the coil, leading with the north pole. Once the magnet is completely through, move it back to its original position.

Move the magnet straight through the coil, only this time leading with the south pole. Once the magnet is completely through, move it back to its original position

Put the magnet in the center of the coil, but don’t move it.

Put the magnet on the outside of the coil. Repeatedly move it up and down while outside of the coil.

Keeping the magnet outside of the coil. Repeatedly move it back and forth horizontally.

Place the magnet back inside of the coil. Now repeatedly switch the polarity of the magnet by pressing the button toward the bottom-right of the page over and over again.

Part B

After producing electricity in many different ways, describe what causes electricity to flow in the coil? In your response, describe the types of forces acting on the electrons and how they result in movement.

As you know, loudspeakers are used for communication at sporting events, and in schools or supermarkets. Research loudspeakers on the Web. Describe the components of a speaker and explain how it produces sound. In particular, explain how the force on a current-carrying wire in a magnetic field is used to make a speaker operate.

Throughout this lesson, you learned about the lives and contributions of key scientists in this area of physics. Create a timeline that ties them all together. The timeline does not need to be highly detailed, but it should do the following:

Include at least the four major scientists covered in this unit: Oersted, Ampère, Faraday, and Tesla.
Include key contributions of each scientist and provide a year, if possible, for those contributions.
Note any relationships among these and other scientists, especially if one developed something based on the work of another.

Nuclear Reactions & Applications

By Academic Wizard Blog

Nuclear Reactions & Applications

Scientists such as Heinrich Hertz, Philipp Lenard, Max Planck, and Albert Einstein made scientific contributions that ultimately demonstrated that light is electromagnetic radiation, and that it has a “dual nature.” Some electromagnetic phenomena are best explained with a particle model, and some with a wave model. In a sense, “wave” and “particle” are just easy mental models for light. We employ them because we are used to seeing waves and particles—such as those in water waves and baseballs—in our daily lives. Electromagnetic radiation is a basic concept in physics, but it doesn’t fit completely into one of these neat little boxes.

Research and discuss at least one modern technology that employs electromagnetic radiation and that can be explained by the wave model, the particle model, or a combination of the two. Some possible technologies include solar panels, burglar alarms, cameras, and cell phones.

Comprehensive General Answer:

1. Introduction
This experiment investigates the principles underlying the observed physical phenomenon, applying relevant scientific laws and mathematical relationships. The theory section should discuss the scientific concepts being tested, supported by formulas and definitions of each variable involved. For example, if the experiment measures motion, Newton’s laws, kinematics equations, and variables like displacement (s), time (t), velocity (v), and acceleration (a) would be described. The goal is to establish the theoretical basis for the experiment, enabling a clear understanding of why and how the observed results occur. References should be provided for any external resources used, following proper citation standards.

2. Hypothesis
If the experiment is conducted under the specified conditions, then the measured outcome will align with the theoretical prediction due to the consistency of the physical laws being applied.

3. Analysis
The analysis should contain processed experimental data, organized into clear tables and visualized through charts or plots. Percent error calculations for each dataset compare experimental results with theoretical values, providing insight into measurement accuracy and experimental reliability.

4. Conclusion (What You Learned)
From the experiment, it can be concluded that the observed results generally support the theoretical framework, though minor deviations may occur due to measurement errors, environmental factors, or instrument limitations. This reinforces the importance of accurate measurement and control of variables in experimental science.

What is a robust and useful theory according to the textbook?,
What goes into creating a theory?,
What is the difference between a theory and an idea?,
What is one dimension for a concept of humanity from Feist et al. (2021)?,
What is an example illustrating this dimension?

Comprehensive Answer:

According to Theories of Personality by Feist, Feist, and Roberts (2021), a robust and useful theory is one that is internally consistent, comprehensive, falsifiable, and practical. Such a theory should explain observed phenomena, predict future outcomes, and integrate existing research findings into a coherent framework.

Creating a theory involves systematic observation, gathering empirical evidence, identifying patterns, and formulating general principles that explain and predict behavior. This process requires rigorous testing, peer review, and refinement based on new data.

The key difference between a theory and an idea is that an idea can be a personal opinion, assumption, or untested concept, while a theory is grounded in evidence, has undergone systematic evaluation, and can reliably explain and predict phenomena.

One of Feist et al.’s six dimensions for a concept of humanity is determinism vs. free will. This dimension examines whether human behavior is shaped by forces beyond our control (e.g., genetics, environment) or by conscious choices and personal agency.

For example, a psychologist working from a deterministic perspective might argue that a person’s tendency toward anxiety stems from inherited temperament and early life experiences, while a free will perspective would emphasize the individual’s ability to adopt coping strategies and change their behavioral patterns despite predispositions.

Operant Learning Analysis

By Academic Wizard Blog

Operant Learning Analysis

For this assignment, you will write a paper that presents a detailed analysis of the basic concepts of operant learning.

Please include these topics in your paper:

1. Basic Procedures, Principles, and Processes

a. Define the 4 basic types of consequences that can be used in consequence-based interventions and the effect of each. b. Define an extinction procedure and the resulting effect. c. Pick 3 of the 5 procedures discussed in your answers to “a” and “b,” and explain how you could use them to reduce the frequency of talking to a peer (inappropriately) while the teacher is talking. d. Now identify which behavioral process or principle is associated with each of the following procedures: shaping procedures, overcorrection procedures, coercive interactions, bonuses/commission, timeout procedures, response redirection, response cost procedures, and planned ignoring. In other words, for each of the 8 intervention procedures listed in item “d,” state which behavioral process or principle it is associated with and how you know. (Hint: Your answers will always be one of the five terms you have already discussed in items “a” and “b” above.)

( Additional information to note: The related terminology of behavioral procedures, principles, and processes can understandably be very confusing. Remember that behavioral procedures describe the environmental manipulations that are made in order to demonstrate the related behavioral processes. The behavioral processes occur because of the functional relationships between the environmental manipulations and the behavior, which are referred to as the behavioral principles involved.

For example, “As a behavior change procedure, extinction provides zero probability of reinforcement. As a behavioral process, extinction refers to the diminishing rate of a previously reinforced behavior when that behavior no longer produces reinforcement. As a principle, extinction refers to the functional relation between withholding reinforcement for a previously reinforced behavior and the resultant diminishing rate of response,” (Cooper et al., 2020, p.594).) Operant Learning Analysis

2. Characteristics of Effective Consequences

a. Describe several characteristics that make consequences more or less effective. Be sure to include recommendations regarding their immediacy/contiguity, contingency, and intensity (with respect to punishing stimuli). b. Describe at least two ways to identify effective consequences for an individual. (Refer to chapter 11 in Cooper et al. (2020) and chapter 6 in Mayer et al. (2022).)

3. Use of Reinforcement versus Punishment Procedures

a. Describe some potential side effects of using punishing stimuli and punishment procedures. b. Explain how reinforcement and punishment procedures should be selected.

· Which should be prioritized and why?

· Could/should they both be incorporated into a treatment package and how?

Your paper should be 5-8 pages in length and written in APA style. It should include at least 5 peer reviewed references. These can be books or articles where you got your information to help answer the questions, or peer-reviewed journal articles that provide examples of interventions or procedures you discussed in your paper (e.g., an article that used extinction to reduce a problem behavior).

Please note: Your assignment should be submitted in a Word Document format using Times New Roman 12. The assignment must use APA format (See link to APA publication style in the course site resources.) Please include an appropriate heading on your paper and references to support methods or procedures used.

Please be sure to save your work using the naming convention:

By Academic Wizard Blog

Proposed Psychological Disorder Study

The Proposed Study Essay assignment is designed to assist students with conceptualizing a new research study that builds on what they’ve learned about psychological disorders and treatment and some of the newest, peer-reviewed scientific literature on the topic. In the process of your work, you will:

1. read and digest a portion of the scientific literature (2 peer-reviewed journal articles),

2. analyze the articles for their content, strengths, and limitations, and

3. design a proposed study that would extend the literature on this disorder in a meaningful way.

Learning Outcomes

By completing this assignment, you will learn how to:

· Identify and explain key terms and concepts in psychological science and research.

· Discuss the biological, physical, cognitive, emotional, and social factors that influence this specific disorder / syndrome.

· Explain research methods used in the study of this specific disorder / syndrome.

· Integrate reflective thought and scientific reasoning to develop novel and relevant research questions.

· Predict / hypothesize potential outcomes of research questions on the basis of existing knowledge from the textbook and scientific articles.

Tasks Proposed Psychological Disorder Study

In this written essay, you will build on the information presented in the two articles to propose a new study of the disorder that will address the limitations of past research and contribute to the scientific knowledge base. You will detail the rationale, goals, design, research questions, hypotheses, variables, and potential implications of their proposed study.

Preparation:

· Ensure that you have completed all readings and assignments in the PSY 101 course to date / prior to this assignment.

· Review APA style for reference pages, including how to use capitalization, italics, and indentation in listing each cited article in your essay.

· Review APA style for parenthetical (in-text) citations so you can effectively cite information you did not generate yourself and avoid plagiarism.

To successfully complete this assignment, you will:

1. Read the 2 peer-reviewed, scientific journal articles. The first article is about the etiology of the disorder, and the second article is about the treatment of this disorder.

2. Article 1: Proudman et al., 2021 (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8134814/)

3. Article 2: Karrouri et al., 2021 (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8610877/)

4. Design a proposed study in essay format.

Please use this chart to help you organize your assignment:

Step with Directions

Description and Details

Step 1: Read the 2 peer-reviewed, scientific journal articles. The first article is about the etiology of the disorder, and the second article is about the treatment of this disorder.

· Article 1: Proudman et al., 2021

· Article 2: Karrouri et al., 2021

Step 2: Organize the structure and content of your essay into the following 5 sections.

· It is strongly recommended that you follow this suggested structure to assist with organization and clarity of your essay.

· Each paragraph / section should start with a strong topic sentence, followed by several sentences containing information to support your claims.

· Each paragraph/section should include at least one citation in APA format.

1. Description of the disorder. This section should discuss the incidence and prevalence of the disorder, its symptoms, and any important sex/gender or age differences in its presentation.

2. Risk for developing the disorder. This section should identify at least 3 evidence-based risk factors (i.e., factors that have been shown to be related to the development of the disorder in research) and explain why each is relevant in the etiology of the disorder.

3. Common treatments for the disorder. This section should briefly review and explain at least two existing treatments for the disorder. At least one of the treatments reviewed MUST be psychological (non-pharmacological) in nature.

4. Identify gaps in our understanding of treatment for this disorder. Identify at least one limitation of existing treatment research for this disorder. Explain why this gap in our understanding is important to address in future research.

5. Propose a study that would help us better understand and improve treatment for this disorder. This proposed study may directly address the gap in our understanding of the disorder’s treatment (identified in the previous section). You must include:

6. At least one research question and associated hypothesis . In stating your research question and hypothesis , clearly identify your independent variable (s) and your dependent variable (s).

7. The sample of people to be studied. In describing your sample of participants, include important demographic characteristics of participants (e.g., age, sex, gender, race/ethnicity, education level, sexual orientation , etc.) and how you would recruit these individuals for participation.

8. The research methods you would use to measure your variables. In explaining your research methods, include what type of research design (correlational/experimental), timeline (cross-sectional or longitudinal) and measures (surveys, observations, experimental tasks, etc.) you would use.

9. The importance of this study. Include the potential implications of your study results for extending the scientific literature on treatment of this disorder.

Step 3: Prepare a References page that lists each of your 3 sources in APA style. Note that you will need to list your textbook as one source as well as each of your 2 peer-reviewed journal articles as the other two sources.

The References page will be the last page of your research paper. You do not need to have more than 3 references.

Requirements Proposed Psychological Disorder Study
