Gravity: The Force That Pulls.
🎯 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
Gravity is the force that pulls objects toward each other. On Earth, gravity pulls everything toward the center of the planet, giving objects their weight.

Steps
Review the background information on Magnets before starting.
Construct a catapult from popsicle sticks and rubber bands. Launch a marshmallow from different angles and measure the distance. Find the angle that gives the longest launch.
Look for patterns in your observations.
Make a graph or chart showing your results.

Question 1
1 of 3What causes an object to accelerate?
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.”
