This is a fun stem challenge that I call "Escape the Island" Students will design and build a raft from mostly materials they find outside. If they can get their raft to move from one end of a Rubbermaid bin to the other by blowing on the sail and it floats for 15 minutes they win. This activity is a lot of fun and does not require the teacher to purchase a lot of materials.
Here is what is in the packet:
1. Directions for the STEM challenge
2. 2 prototype worksheets
3. An analysis and reflections worksheet
