Electricity.
🎯 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
Wetlands like marshes and swamps filter water, prevent flooding, and provide habitat for many species. They are among the most productive ecosystems on Earth.

Steps
Study the diagram and label the parts you recognize.
Compare the skeletal structures of a bird wing, human arm, and whale flipper using diagrams. Identify homologous bones and write what this tells us about common ancestry.
Watch carefully for any changes and note the time.
Create a data table to organize your measurements.

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.”
