Experiment⭐ 30 XP⚡ Spark LabClassifying Life into Kingdoms (Part 2)
Magnetism.
🎯 Your mission
Predict it first. Then prove yourself right (or wrong).
⚡ The twist
Energy never disappears — it just hides somewhere else.
Mind = Blown
⚡ Static electricity is the same physics as lightning, just smaller.
Make a hypothesis first
Before you start: which will move faster, and why?
What You'll Learn
Scientists classify living things into groups based on shared features, starting with broad kingdoms such as animals, plants, fungi, and bacteria. Every organism also receives a two-part scientific name, like Homo sapiens for humans.

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.”
