Lesson⭐ 30 XP⚡ Spark LabNewton's First Law: Objects at Rest
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
Newton's first law states that an object at rest stays at rest and an object in motion stays in motion unless acted on by an unbalanced force. This is called inertia.
Key Words
- gravity
- friction
Steps
Read about Simple Electricity and write down three key facts.
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.

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.”
