Product Description

Looking for a fun Halloween activity that incorporates science, technology, engineering, and/or math? Halloween STEM / STEAM Challenges are collaborative, brain-busting work disguised as fun!

The basic premise:

Students work in partners or groups against a list of criteria and constraints to build the longest “bone” bridge possible.

This challenge goes beyond Halloween! Connect this to the skeletal system, bridges/transportation, and/or forces (specific ideas included).


Note: This is the printable version. If you are in a 1:1 / paperless classroom, you will want to check out the digital option for use with GOOGLE SLIDES (TM) instead.

If you have questions about which version is right for you, please feel free to leave me a question using the product Q&A below.

What are teachers saying about Bone Bridge?

“The class had so much fun with this challenge! When we started putting weights on each bridge they were cheering so loud other teachers had to come see what was happening.”

“I love the optional extensions and discussion questions! That will help me differentiate for my high functioning students.”

“Another great STEM challenge to add to my curriculum! Well done!”

“Used the Bone Bridge for my evaluation lesson! Went great and the kids loved it!” (feedback left in the Halloween 5-in-1 Bundle)

“This was perfect! Much more challenging than the students expected!”

"Love it! I hate giving up an instructional day for Halloween. This is a challenge and a great use of time on an otherwise crazy day. Thank you!"


Benefits of this STEM Design Challenge:

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

- 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 approximately 60 – 90 min. if you are including data gathering and analysis rather than just building for fun. I recommend working on STEM Design Challenges in multiple iterations to get the full value.
