Who knew a project using spaghetti could be so engaging? Kids love this tower-building event with the unlikeliest of materials- spaghetti and one marshmallow. You will enjoy the easy-prep and ready-made lab sheets.

Please note: This challenge is available as part of several money-saving bundles!

What is the challenge?

Students will use raw spaghetti strands to build a structure that will hold weight at the top. There are variations of this project included in the resource.

What is your prep?

You will need supplies in addition to this package. This includes spaghetti, marshmallows, tape, and string. Students also need scissors. You will prepare bins with the materials and copy the student lab sheets.

What is included:

  • This package is jam-packed full of teacher directions, lab sheets, hints, and photos. The original challenge includes two versions of lab sheets.
  • This challenge pack now contains 2 bonus lessons! Check the preview to see the Bell Tower Challenge. It is very similar to the Spaghetti Challenge but is a challenge you can use especially at Christmas time. Directions, helpful hints, constraints, lab sheets, and photos of the Bell Tower are all now included.
  • There is also a Blueprint Version of the challenge. It includes special directions, hints, photos, constraints, and lab sheets.
  • But, there is even more! Another file contains editable pages for the forms- which includes the constraints and lab sheets.
  • And, what if you are like me and forget to buy the marshmallows? I added a page of photos and tips for using an alternative to the marshmallow that was really challenging and added a new problem to solve!

This a fun design challenge and is, by far, the activity my lab students most request to do again!

Be sure to check the PREVIEW and see all the items included in this amazing challenge!

What are teachers saying?

  • "I am so glad that I purchased this stem challenge! My students LOVED it! The first time they did the challenge, it really tested them...they were really excited about building until they found out what the materials were! I noted so many things about teamwork, revisions that they made, and also how failure impacted them in different ways. That night, they each had to go home and write down ideas about how they would improve their design. The next day: WOW! They were revived and confident about building again, given the previous day's experience! Every group experienced more success than the day before and they worked so much better as a team. I'm really excited about the next challenge that we'll be doing this week!"

This challenge is a perfect companion to these:
