Sure! Below is a structured template for your lab portfolio, filled with placeholder text that you can edit once you perform the experiments and gather data. I will guide you on how to fill it out based on your observations and findings.
Science Portfolio ● Semester A
Forces in Nature Portfolio
Virtual Lab
Instructions:
Read through the lab completely before beginning the experiment. Check the Lab Rubric at the end of this document for grading. Collect all necessary materials before beginning the lab. Create a copy of this lab so you can fill it out as you go. Do not request editing access. You can print it and write on it, or you can make a copy in Google Docs or Microsoft Word (File → Make a Copy). Download (word doc or pdf) a finished copy of this worksheet that includes your answers. Upload it into the Non-Contact Forces Portfolio 1 Dropbox in Connexus (Unit 6, Lesson 7). Reach out to your Science teacher if you have any questions!
Faraday’s Electromagnetic LAB
I. Electromagnet:
→ Click the “Electromagnet” tab.
→ Make sure “DC” is selected, your electromagnet has 4 loops, and “Show Field,” “Show Compass,” and “Show Electrons” are all checked.
II. Electromagnet Questions:
-
How does the number of loops in the wire affect the strength of the electromagnet?
Type Answer HERE: [Your answer based on observations, e.g., "Increasing the number of loops increases the strength of the electromagnet."] -
What happens to the compass when the electromagnet is activated?
Type Answer HERE: [Your answer based on observations, e.g., "The compass needle moves when the electromagnet is activated, indicating the presence of a magnetic field."]
III. Generator
→ Click the “Generator” tab.
→ Make sure “Show Field” and “Show Compass” are checked.
IV. Generator Questions:
-
Explain how a generator produces electricity.
Type Answer HERE: [Your answer, e.g., "A generator converts mechanical energy into electrical energy through electromagnetic induction."] -
What effect does moving the magnet have on the current produced?
Type Answer HERE: [Your answer, e.g., "Moving the magnet faster increases the current produced, as it induces a stronger magnetic field."]
Balloons and Static Electricity LAB
Instructions:
Carefully read the directions to complete the virtual tasks in order. Then answer each of the questions given.
- [Describe your actions with the balloons to observe static electricity.]
V. The Balloon and Static Electricity Questions:
-
What happens to the charges when two balloons are rubbed together?
Type Answer HERE: [Your answer, e.g., "The balloons become negatively charged, and they repel each other due to like charges."] -
What occurs when a negatively charged balloon is brought near a neutral object?
Type Answer HERE: [Your answer, e.g., "The negative charges in the neutral object move away due to repulsion, resulting in an attractive force."] -
Describe what occurs when two similarly charged objects are brought close to each other.
Type Answer HERE: [Your answer, e.g., "They repel each other due to like charges."] -
Describe what occurs when a positively charged object is brought near a neutral object.
Type Answer HERE: [Your answer, e.g., "The positive charge attracts electrons from the neutral object, causing an attraction."] -
Explain how you can determine the charge of an object.
Type Answer HERE: [Your answer, e.g., "By bringing the object close to other charged objects and observing whether they attract or repel."]
VI. Friction, Conduction, and Induction Video
[Indicate you have watched the video and summarize any key points.]
VII. Friction, Conduction, and Induction Questions:
- Fill in the Blank
A. Friction is rubbing two objects together, causing one object to pick up electrons from the other object.
B. Conduction is the transfer of electrons from one object to the other by direct contact (touch).
C. Induction occurs when charges in an uncharged object are rearranged due to the attraction or repulsion of charged particles which are NOT TOUCHING.
VIII. Analyzing the Data:
-
Based on your observations, which setup would likely produce the strongest charge?
Type Answer HERE: [Your answer based on data.] -
If she wants to attract the sphere, what should she do?
Type Answer HERE: [Your answer based on options provided, e.g., "She should place a positively charged rod near the left sphere."] -
What is the best conclusion from the student's electromagnet experiment?
Type Answer HERE: [Your answer based on the options provided.]
VII. Reading & Evidence Questions: Follow the instructions to open the required MyON Reading for this portfolio. Use the assigned books to help you answer the following questions.
-
How is electricity created? (pages 6 - 9)
Type Answer HERE: [Your answer.] -
What is static electricity? Provide an example (pages 10 - 11)
Type Answer HERE: [Your answer.] -
How do conductors and insulators work together to power your house? (pages 14 - 15)
Type Answer HERE: [Your answer.]
Once you complete the experiments and gather your observations, don't forget to fill in your answers to make the repository your own! Good luck with your portfolio submission!
