One of our favorite STEM challenges is to build a boat, so I knew students would love this Quick Challenge activity to build a raft. Students will love engineering the materials and creating a sturdy platform and they will cheer as they test it with weights.

Note: This quick challenge is available as part of money-saving bundles:

What is the challenge?

Students build a flat bottom raft and then test its ability to float and hold a little bit of weight. You will love the easy prep for this challenge and the problem-solving that occurs when the rafts begin to sink. Get ready for cheering or groaning as the rafts are tested!

What is your prep?

Materials needed for the STEM Challenge include straws, craft sticks, and masking tape. You will also need a water bin to test the rafts. A simple teacher's guide is included. It's a fabulous exploration time with limited supplies and spectacular results!

The package specifically contains:

  • Cover sheet
  • Teacher Background
  • 3 pages of Teacher Direction,
  • Set of Criteria cards for students (in 2 versions)
  • Lab Sheet with answer samples
  • 2 pages of photos
  • Scoring rubric
  • Terms of Use
  • All forms are provided in an editable format!

Simple teacher procedures and tons of tips are included. Just talk about the criteria of the task, and let them get busy planning, designing, collaborating, and learning!

Your students will love building and testing their rafts!
