Simulation⭐ 30 XP⚡ Spark LabGravity: The Force That Pulls
Energy Transfer.
🎯 Your mission
Push the limits. See what changes.
⚡ The twist
Speed isn't the same as force. Don't mix them up.
Mind = Blown
🔥 A bolt of lightning is 5 times hotter than the surface of the sun.
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.
Key Words
- acceleration
- velocity
- momentum
Steps
Review the background information on Energy Transfer 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.

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.”
