Hoist the anchor, hold the mainstay, and grab a pool noodle! Our last #summerSTEMchallenge is all about buoyancy, and it’s made with materials you probably already have at home!
Challenge: Create a boat and find out how much weight your boat can hold without sinking.
- pool noodle
- coffee stirrer / straw / chopstick
- StoryBots Sails Printable
Step 1: Cut the noodle
👩👧 This is a grown-up job. Using a craft knife (we used a bread knife!) cut a 1 inch disk off the noodle.
Step 2: Set the sails
Print out the StoryBots Sails and tape a stick to the back (we used coffee stirrers).
Step 3: Put it all together
Insert the sail firmly into the noodle.
Step 4: Experiment time!
Try out your boat in a kiddie pool, the sink, the tub, or a shallow tub. How can you make this project even better?
Try out these extension ideas:
- How can you change the sail to improve your boat?
- How many pennies (or other cargo) can your boat hold?
- Can you add a motor?
Hope your summer is full of curiosity, questions, and some really silly songs. You can find even more fun stuff at StoryBots.com!
