Simple Machines: Pulleys (Part 2).
🎯 Your mission
Set it up. Test it. Be amazed.
⚡ The twist
Nature loves to surprise the careful watcher.
Mind = Blown
🔬 The more you look, the more nature shows you.
Make a hypothesis first
Before you start: write down what you think will happen, and why.
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
