Lesson⭐ 30 XP⚡ Spark LabElectric Circuits (Part 2)
Forces and Motion.
🎯 Your mission
Master the concept. Use it tomorrow.
⚡ The twist
Energy never disappears — it just hides somewhere else.
Mind = Blown
⚡ Static electricity is the same physics as lightning, just smaller.
Make a hypothesis first
Before you start: which will move faster, and why?
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
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?

Where you see this in real life
This is why airplanes can fly and why rockets reach space.
Stretch Challenge
Try this in real life this week.
This week, find one thing in your house that turns one kind of energy into another.
For the dinner table
“Show me something at home that uses this kind of energy.”
