Standard:
MS-PS1-1.
Develop models to describe the atomic composition of simple molecules and extended structures.
Essential Question:
How do electric charges exert force on each other?
Introduction
Hello Scientists!
WONDER: How do electric charges exert force on each other??
This is the question that you and your classmates will investigate in your role as student scientists.
Task
You will investigate and explain that electric currents and magnets can exert force on each other.
Process
INSTRUCTIONS:
1. Explore the virtual simulation . . .
- While you were interacting with the balloon activity, explain the relationship between the electrical charges. What did you notice?
- Elaborate on what you explored during the activity. Minimum of 3 complete sentences.
2. Watch the video . . .
- Describe and draw the Bohr Model.
- What forms an electric current?
-How does electricity work?
-What do electrons do?
-What is short circuiting?
- Write a summary of the video. Minimum of 4 complete sentences.
3. Investigate the presentation to learn more about magnetic fields ! ! !

- All matter is made up of very small particles called Atoms. What are atoms made of?
- Charged objects exert a force: a push or a pull on other charged objects. Describe the reason why objects attract or repel.
- When trying to understand the transfer of electrons, think of a chalkboard and eraser. How might this illustrate electron transfer?
- What is static electricity? Provide an example.
