This tower building STEM / STEAM Challenges is perfect for summer – or any time of the year! It brings the joy back to your classroom with collaborative, hands-on, brain-busting work (disguised as fun)!

If you have spare index cards, at least 30 minutes, and a class to inspire, run this challenge as a fun, quick task for a rainy day, or select from multiple options provided to add depth and rigor to extend this activity to days or weeks of active learning!

The basic premise:

Individually, or in partners/groups, students work against a criteria and constraints list to build a tower designed for height and/or stability. You can choose to run the challenge as a single 20-30 minute fun building task, or select from multiple options to add layers of depth and rigor. (Please see the downloadable preview to get an idea of your options.)

Note: Included in this resource is the regular "anytime" version and the Valentine's Day Cards in the Clouds version.

Sample/suggested materials for each student or group:

(Materials you’ll need to do the activity are easily modified. )

Sample/suggested materials:

For each student or group:

– 20 or more 3x5 index cards (or substitute business cards, card stock, or poster board)

– Tape (constrain to 12 in. or less)

– Rulers/measuring tapes (tip: pick up paper measuring tapes from Ikea)

– Copies of data recording & analyzing handouts

– Optional: Scissors, pipe cleaners


Benefits of this STEM Design Challenge:

- Focus on critical thinking, problem solving, and application of learning

- Helps students develop growth mindset traits like persistence and resilience

- High levels of student engagement

- The potential to hit upon all NGSS ETS standards depending on the depth and number of iterations you choose to implement in your classroom (modifications included)

- Highly flexible and differentiated for materials, timing, grade levels, and rigor.

Each design iteration should be planned for ~60 min. if you are including data gathering and analysis rather than just building for fun. If you add extension activities, you will need to adjust timing accordingly.
