Experiment⭐ 30 XP⚡ Spark LabKinetic Energy: Energy in Motion (Part 3)
Simple Electricity.
🎯 Your mission
Predict it first. Then prove yourself right (or wrong).
⚡ The twist
The opposite of what you expect is often what happens.
Mind = Blown
🔥 A bolt of lightning is 5 times hotter than the surface of the sun.
Make a hypothesis first
Predict: what happens if you double the force?
What You'll Learn
Kinetic energy is the energy of motion. A moving car, a rolling ball, and a flying bird all have kinetic energy. The faster an object moves, the more kinetic energy it has.
Key Words
- force
- energy
Materials Needed
- cardboard
- marbles
- paper clips
- rubber bands
- blocks
Safety First
- Wear safety goggles when mixing liquids.
- Wash hands after handling materials.
Steps
Review the background information on Simple Electricity before starting.
Build a simple circuit using a battery, wire, and light bulb. Then add a switch and test what happens when you open and close it.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.

Question 1
1 of 3What type of energy does a moving object have?
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.”
