Simple Electricity.
🎯 Your mission
Play with the model. Break it. Understand it.
⚡ The twist
Speed isn't the same as force. Don't mix them up.
Mind = Blown
⚡ Static electricity is the same physics as lightning, just smaller.
Make a hypothesis first
Guess: where does the energy go?
What You'll Learn
Energy can be transformed from one form to another but cannot be created or destroyed. A light bulb converts electrical energy into light and heat energy.
Key Words
- kinetic
- potential
- work
Steps
Read the introduction and identify the main idea of this lesson.
Set up a pendulum with string and a washer. Change the string length and count swings per minute for each. Graph your results.
Compare the before and after states.
Write your conclusion: did the results match your hypothesis? What would you change next time?

Question 1
1 of 3What is needed for a simple electric circuit?
Where you see this in real life
You use this every time you flip a light switch, ride a bike, or kick a ball.
Stretch Challenge
Try this in real life this week.
Time how long a small ball rolls down something, then change the slope and try again.
For the dinner table
“Show me something at home that uses this kind of energy.”
