Experimentโญ 30 XPโก Spark LabNewton's Third Law: Action and Reaction (Part 2)
Simple Electricity.
๐ฏ Your mission
Run the experiment. Find out what really happens.
โก The twist
Speed isn't the same as force. Don't mix them up.
Mind = Blown
โก 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 third law states that for every action there is an equal and opposite reaction. When you push against a wall, the wall pushes back on you with the same force.

Steps
Read the introduction and identify the main idea of this lesson.
Build an electromagnet by wrapping insulated wire around a nail and connecting it to a battery. Test how many paper clips it can pick up. Try adding more wire coils.
Use your senses (except taste) to describe what you notice.
Write a summary of your findings in 3-5 sentences.
Check Your Understanding
Question 1
1 of 3What is gravity?
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
โShow me something at home that uses this kind of energy.โ
