Simple Electricity.
🎯 Your mission
Learn the rule. Then catch nature using it.
⚡ The twist
Speed isn't the same as force. Don't mix them up.
Mind = Blown
⚡ Static electricity is the same physics as lightning, just smaller.
Make a hypothesis first
Guess: where does the energy go?
What You'll Learn
Light travels in straight lines until it hits a surface and bounces off, which is called reflection. A smooth mirror reflects light evenly so you see a clear image, while a rough surface scatters the light in many directions.
Key Words
Tap a word to see its definition.
Steps
Look at the vocabulary words and write a definition for each in your own words.
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.
Observe what happens and describe it in detail.
Record your observations in your science journal with measurements and descriptions.
