Next Activity (Horizontally)
The ship is away from the dock and we need to load supplies to build rescue rafts on board.
After Activity Questions
What was helpful about using a pulley system to deliver the supplies?
Can you think of any other way pirates could use pulley systems on a pirate ship?
Simple machines don’t take batteries or fuel to help us work. Since pirates existed long before electricity and diesel-powered cranes, we need to use these simple machines to help us load up our ship and prepare to set sail in search of buried treasure.
First Activity
It's time to load the supply boxes onto our pirate ship
After Activity Questions
Have you ever seen an inclined plane near where you live or play?

Have seen or used chopsticks before?
Are chopsticks considered to be levers?
Is it hard to use chopsticks?
