Forces and Motion.
๐ฏ Your mission
Predict it first. Then prove yourself right (or wrong).
โก The twist
Energy never disappears โ it just hides somewhere else.
Mind = Blown
โก Static electricity is the same physics as lightning, just smaller.
Make a hypothesis first
Before you start: which will move faster, and why?
What You'll Learn
A force is a push or pull that can change an object's motion, shape, or direction. Forces are measured in Newtons and can act through contact or at a distance.
Key Words
- repel
- motion
Materials Needed
- cardboard
- marbles
- paper clips
- rubber bands
- blocks
- spring scale
Safety First
- Dispose of materials properly after the experiment.
- Handle glass items carefully to avoid breakage.
- Do not mix unknown chemicals together.
Steps
Read the introduction and identify the main idea of this lesson.
Construct a catapult from popsicle sticks and rubber bands. Launch a marshmallow from different angles and measure the distance. Find the angle that gives the longest launch.
Note any unexpected results and think about why they happened.
Share your findings with the class or a partner and discuss what you learned.

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
