This product includes challenge directions as well as a two page student recording sheet for a STEM boat building challenge.
You can design this challenge in many ways:
1. Have your students fill their boats with a certain number of pennies and create a time requirement. For example, all boats must be able to hold 75 pennies for 10 minutes.
2. Have your students design a boat that can hold the most number of pennies (30 pennies minimum).
If you are looking to build background knowledge on boats (including the concept sink and float), see my QR code actvity here.
