How Do Electrons Work?

I want to see what type of scientist you can be. The task today asks you to check out some movies and then create a report explaining what you have found out.

Your task is to watch the following movie. Take notes because you have to explain how electrons work in electrical circuits.

In your inquiry book

Include diagrams and text or just use diagrams to explain how they work. You need good labels, arrows etc that help us understand your diagram.

Use the technical terms that the movie uses.

 

 

Check out this second movie if you need more information!

This Alessandro Volta task is to be completed on Tuesday May 1st.

Alessandro Volta

AlessandroVolta_BatteryMaker1

AlessandroVolta_BatteryMaker2

A) Create timeline of events in Volta’s life in chronological order.

B) In pairs, play the roles of Galvani or Volta in a debate about who is correct.

Write the for and against arguments for these two scientists to document your ideas.

 

C) Post a comment below in your science group to these questions:

  1. Why did the scientists disagree?

  2. What was the first thing Volta did when he disagreed with Galvani? Why?

  3. Did either of them change their ideas? Did they change other people’s ideas?

  4. What could have happened if Volta had agreed with Galvani?

  5. Do you think this cartoon is reliable?

  6. Can we trust the information? Why?

  7. Who do you think could have written it? Why?

 

2. Hey scientists! After completing the Volta task it is time to move on to this “How It Works” assignment.

Watch the video below and answer the questions in your Science scrap book. Then draw a labelled cut-away diagram of a battery in your science book.
