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



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.



Wave Energy

1. Where is the world’s first wave energy farm that is connected to the electricity grid?

2. Where does the energy from a wave come from?

3. What is more than 70% of the Earth’s surface covered with?

4. What is caused when the wind blows over the surface of the water?

5. What is created when some parts of the water are pushed down, other areas are pushed up and the water starts spinning?

6. The onshore wave energy plant is connected to what out at sea?

7. What moves when the pipes that pump water back to the plant at high pressure, force turbines to spin to make more waves?

8. Where do the buoys sit?

9. The electricity that is being produced is being used to power a nearby…

fuels by the end of the century? Explain your answer.



Read ‘Where does electrical energy come from?’ and watch the two short clips below.

Film an interview with your science group, discussing the following questions:

What types of energy can be transformed into electrical energy?

How can types of energy be transformed?

Which sources of energy are renewable? Why do you think that?

Which sources of energy are sustainable? Why do you think that?

What are you still wondering about?
