Motion and Forces.
🎯 Your mission
Predict it first. Then prove yourself right (or wrong).
⚡ 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
Electromagnets are temporary magnets created by running electricity through a coiled wire. They can be turned on and off and are used in motors, speakers, and MRI machines.

Steps
Read the introduction and identify the main idea of this lesson.
Test Newton's Third Law: blow up a balloon, attach it to a straw on a string, and release. Measure how far it travels with different amounts of air.
Observe what happens and describe it in detail.
Record your observations in your science journal with measurements and descriptions.

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.”
