Can you build a tower out of noodles? This awesome spaghetti tower challenge is perfect for young and older kids! Build the tallest spaghetti tower that can hold the weight of a jumbo marshmallow. Test out those design and engineering skills with a few simple materials. Which tower design will be the tallest and strongest? We love easy and fun STEM activities for kids! 



So you might ask, what does STEM stand for? STEM is science, technology, engineering, and math. The most important thing you can take away from this is that STEM is for everyone!

Yes, kids of all ages can work on STEM projects and enjoy STEM lessons.  STEM challenges are great for group work, too! Easily done in the classroom, with groups, or at home for a screen-free activity, simple STEM challenges encourage many skills, including problem-solving and creative thinking.

STEM is everywhere! Just look around.  The simple fact that STEM surrounds us is why it’s so important for kids to be a part of, use, and understand STEM, from research on the internet to measurements around the house. Ordinary everyday activities use STEM.

From the buildings you see in town, the bridges that connect places, the computers we use, the software programs that go with them, and the air we breathe, STEM is what makes it all possible.

Build a Spaghetti Tower

While you’ve got the spaghetti out, look at this strong spaghetti challenge!

Design Challenge:

Build a tower of spaghetti noodles that will hold a jumbo marshmallow. Make the tallest tower possible from the materials supplied. The marshmallow must be able to sit on top without falling off.

Free Spaghetti Tower Challenge Worksheet

Making a STEM journal? Download and print this handy spaghetti tower sheet to add to it! This is a fantastic way to expand the activity for middle school students. Look at our STEM resources below, including questions for reflection!


If you’re short on time or have to work within a limited time frame. Set a timer! Results are determined by where the students get with the challenge at the end of the time. Ideally, you want to allow 2-5 minutes of planning time, 15-20 minutes of build time, and several minutes for drawing conclusions. Of course, you can determine this based on your schedule or have no time constraint.



  • 20 sticks of dry spaghetti
  • 1 yard or 3 feet of string
  • 1 yard or 3 feet of tape
  • 1 jumbo marshmallow


Present the kids with the challenge! Tell them these are the only materials they can use to complete the challenge.

STEP 1. Share design ideas, discuss structures and strengths, and even sketch ideas before you begin.

STEP 2. Build your design.

STEP 3. Measure towers, compare results, and discuss difficulties and successes! Use our handy questions for reflection printable to get the conversation started.

Note: Your kid’s prototypes and towers should and will look different from our results! Encourage creativity and problem-solving skills. The images provided are for reference.

Design ideas such as a strong base, pillars, and reinforced areas are key to building the strongest spaghetti tower! Check out famous towers (landmarks) around the world for shape ideas. Do a safe internet search and check out the Burj Khalifa building in Dubai. You might get some ideas!

More Engineering Resources

Below you’ll find various engineering resources to supplement the many engineering projects on the website. From the design process to fun books to key vocabulary terms…you can feel confident providing these valuable skills. Each one of the resources below has a free printable!


Engineers often follow a design process. There are many different design processes that all engineers use, but each one includes the same basic steps to identify and solve problems.

An example of the process is “ask, imagine, plan, create, and improve.” This process is flexible and may be completed in any order. Learn more about the Engineering Design Process.


Is a scientist an engineer? Is an engineer a scientist? It might not be very clear! Often scientists and engineers work together to solve a problem. You may find it hard to understand how they are similar yet different. Learn more about what an engineer is.


Sometimes the best way to introduce STEM is through a colorfully illustrated book with characters your kids can relate to! Check out this fantastic list of teacher-approved engineering books, and get ready to spark curiosity and exploration!


Think like an engineer! Talk like an engineer! Act like an engineer! Get kids started with a vocabulary list that introduces some awesome engineering terms. Make sure to include them in your next engineering challenge or project.


Use these reflection questions with your kids after they have completed a STEM challenge. These questions will encourage discussion of the results and increase critical thinking skills. These questions or prompts will help to promote meaningful discussions individually and in groups. Read the questions for reflection here.
