Forces: Push or Pull (Part 3).
🎯 Your mission
Run the experiment. Find out what really happens.
⚡ 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
A force is a push or pull that can change an object's motion, shape, or direction. Forces are measured in Newtons and can act through contact or at a distance.

Steps
Review the background information on Energy before starting.
Build an electromagnet by wrapping insulated wire around a nail and connecting it to a battery. Test how many paper clips it can pick up. Try adding more wire coils.
Draw a detailed diagram of what you observe.
Write a conclusion: what did your results show? Did they match your prediction?

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.”
