Energy Transfer.
🎯 Your mission
Set it up. Test it. Be amazed.
⚡ 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.

Steps
Look at the vocabulary words and write a definition for each in your own words.
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.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.
