Storyboard Tekst
Wow that crane is huge! How does it work?
It is using a simple machine called a pulley.
Wow! I didn't know that!
A pulley is a chain wrapped around a wheel, making it easier to pull things up.
What?
Tell me More!
Guess what I learned today!
I learned about how levers are a simple machine. Like this door handle!
The stairs?
Hey! Lets use the stairs for our science profject!
Cool!
Sure! Stairs are an incline plane.
An incline plane is a tilted surface used to lift heavy loads up high!
A lever is a bar that pivots on a fixed point, or a fulcrum.
Awesome!
