10 STEM Challenges for the Classroom (plus, free printables & worksheets!)

“STEM from the workforce perspective is … more about grooming workers with 21st-century skills who are ready to jump right in,” says Jonathan Herlach for The National Science Teachers Association. 

STEM has a focus on hands-on learning.  STEM challenges that can be integrated into any classroom by teachers who want to prepare their students to succeed in the modern workforce.

These STEM challenges, both the silly and the serious, can be integrated into almost any classroom and can help students develop the skills necessary to thrive. 

10 STEM Challenges for the Classroom

1. The Marshmallow Challenge 


Described in Tom Wujec’s 2010 TED Talk and often used by both business and education leaders to initiate team building and to commence focus on STEM training, the marshmallow challenge involves providing a team of students with twenty sticks of dry spaghetti, one yard of tape, a string, and a marshmallow.

Teams have eight minutes to build the tallest freestanding structure with the marshmallow on top. This is a great activity to begin a STEM class because of the way that it initiates collaboration and deep-thinking in an ancillary and introductory way.

2. Wind Power Challenge


This STEM challenge from Practical Action prompts students to build a wind turbine. The goal of their simple wind machine is to lift a cup off the floor. The activity is for students 7 years old and up. But its a great challenge for middle school aged students too!

3. Design for a Better World 

This challenge is also initiated by Practical Action It asks students to identify a global issue that can be solved or improved through technology. This challenge is for 11-14 year old students. 

Students are asked to research this topic and design a technology that will improve or repair their particular issue. While providing incredible resources for teachers and students, Practical Action has developed a challenge that can be implemented across the curriculum and that includes a “real-world” application to learning.

4. The Egg Drop Challenge


 The egg drop challenge  is a classic! Students design and create a safety container for a raw egg. While the challenge is very engineering and design focused, there’s a great math & business element at play here too.

Resources in this activity are limited. In the downloadable worksheet, students only have $100 to spend. They have to budget accordingly. You, as the teacher, get to set the prices for all of the supplies for the students to buy.

Once students have built their design, hold a class competition to see who created the safest container.

The egg drop challenge is simple and challenging enough for students at all levels to effectively participate and to have a great time.

5. Parachuting Onto Mars 

This STEM challenge Designed by NASA features extensive resources from the organization. The challenge asks students to “design and test a drag device to slow a spacecraft and protect its cargo, as well as calculate the surface area and measure the mass of the spacecraft.”

Students will create a video featuring the process they followed to arrive at their conclusions, and this video can be submitted to NASA as part of the challenge.

6. Cat Meme Generator 


The creators of Raspberry Pi compiled an exhaustive set of resources for integrating Raspberry Pi projects into the curriculum.

One of their funniest resources is a STEM challenge that asks students to create a original cat meme using JavaScript functionality. With memes being a primary language of teens, it seems like a great time to integrate this into the classroom. This guide will walk you through every step, so even if you don’t know how to code, you’ll be able to guide your classroom! 

7. Paper Table Design Challenge 


For this STEM challenge ideas, all you need is cardboard, tape, and newspaper. Students have 20 minutes to build a table that can hold a large dictionary for 60 seconds. Its a quick and easy STEM activity to quickly integrate into the classroom (and it won’t break the bank!) 

8. Ultimate STEM Challenge 

Sponsored by BP, the Ultimate STEM Challenge challenges teams of two to four students to choose from a short list of provided challenges that are based around the theme of thinking creatively.

While this challenge is specifically for UK students, the resources are available to anyone, and teachers can integrate this challenge into their classroom regardless. Because their resources and challenges are so robust, this is a must-consider challenge for teachers looking for new ways to integrate STEM into the classroom. This is certainly a more advanced STEM challenge, but the teacher and student resources provided make it fully feasible and a great opportunity for students to particular in real-world learning through STEM.

9. The Tinkering Challenge 

Not every STEM Challenge needs to solve a serious world issue. STEM learning begins long before our students are saving the world.

The tinkering challenge has students race a toy car from one of end the table to the other without touching the car, altering the track, or touching the table. Students can work with available materials to design ways to move the car within the constraints of the challenge.

10. 3D Shapes Robot Challenge


Build robots out of 3D shapes in this great STEM challenge for pre-k and kindergarten students. It’s helpful to show students how 3D shapes are made by having flat versions too.
