How Circuits Work.
🎯 Your mission
Master the concept. Use it tomorrow.
⚡ 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
Electricity flows through circuits. A simple circuit needs a power source, a conductor (wire), and a load (like a light bulb). Breaking the circuit stops the flow of electricity.
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.
Look for patterns in your observations.
Make a graph or chart showing your results.

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.”
