We all know summer break is essential. Our students need the rest. We do too. A little boredom? Honestly, it’s good for them. But after a week or two, that freedom can start to feel long, and having a few fun and purposeful summer activities ready to go can make a big difference.
Whether you’re teaching summer school, running a camp, or just want to offer something creative and brain-boosting, these summer STEM challenges are a great way to keep kids learning while still having fun
The Summer Slide and Why STEM Helps
Here’s something you might not know: according to research from the National Summer Learning Association, students can lose up to two to three months of math skills over the summer. Reading slides, too, but STEM subjects are especially vulnerable.
The good news? STEM challenges that feel like play help keep those skills sharp. When students tinker, build, measure, test, and improve, they’re practicing problem solving, critical thinking, and collaboration.
These kinds of projects keep students busy, and they help them grow.

How to Get Your Students Excited About Summer Learning
Getting middle schoolers pumped about learning during summer might feel impossible. But here’s what works for me:
-
Keep it hands-on — kids love building and testing things, not just worksheets.
-
Make it social — challenges in small groups spark energy and friendly competition.
-
Keep it creative — when students get to design and decorate, engagement skyrockets.
-
Make it meaningful — STEM activities show how science and math connect to the real world.
-
Keep it low stress — fun with a little learning is the goal, not pressure or grades.
With those ideas in mind, I’m excited to share my favorite summer STEM challenges that check all these boxes.
STEM Summer Activities That Feel Like Summer
These four favorites are pulled straight from the classroom-tested resource:
✅ Summer STEM Games, Math Activities, and Challenges
1. Flying Discus Challenge
Students work in teams to design and decorate a discus using paper plates. They’ll test different ways to add weight and balance before competing to see whose design flies farthest. They’ll collect data, analyze what worked, and make redesigns to improve performance.
Materials: paper plates, markers, stickers, tape, coins or washers, measuring tape.
Directions:
-
Teams of 4–5 create a discus using two plates and add decorations and weight.
-
Launch the discus and measure distance.
-
Record and compare results; allow for redesign rounds.

2. Floating Noodle Castle Challenge
Students are given pool noodle rings and toothpicks to build a floating castle that stays intact in water. This activity builds problem-solving, buoyancy awareness, and group planning.
Materials: foam pool noodles (cut into ½ inch rings), toothpicks, scissors, plastic bin or container of water.
Directions:
-
In groups, students build a noodle castle that must float and stay together.
-
Test it in water, refine it, and award points for creativity and structural integrity.

3. Water Balloon Catapult Challenge
Students build a catapult that launches water balloons across a field or courtyard. This activity is great for teaching about force, trajectory, and simple machines—plus it adds a splash of summer fun.
Materials: popsicle sticks, rubber bands, plastic spoons, tape, balloons, measuring tape, tarp or field area.
Directions:
-
Students construct their catapults using basic materials.
-
Each team gets three launch attempts.
-
Measure and compare distances, then brainstorm ways to improve.

4. Slip-n-Slide Engineering Challenge
Students create a miniature Slip-n-Slide for small objects like toy cars. They test angles, friction, and speed as they race to build the fastest (but safest) slide.
Materials: plastic tablecloth or vinyl sheet, spray bottles with water, small objects (cars, marbles, rubber ducks), books or ramps.
Directions:
-
Create a slide design using elevation and water.
-
Test three different objects and time how long it takes each to slide through.
-
Redesign for speed and control.

Two More Bonus STEM Challenges
These are easy to prep and full of discovery-driven learning:
5. Egg Drop Engineering Challenge
Students design a container that will protect an egg from a high fall. This classic STEM task encourages creative thinking, testing, and applying the engineering design process.
Materials: straws, tape, plastic bags, cotton balls, paper, string, scissors, raw eggs.
Directions:
-
Students build a structure to protect the egg from a drop.
-
Test from various heights and check for cracks.
-
Reflect and redesign for better protection.
6. Build-A-Bridge Challenge
Students build a bridge that must support a weight across a set span. It combines teamwork, design, and testing of structural integrity.
Materials: popsicle sticks, glue, rubber bands, string, paperclips, books (to create a span), small weights or coins.
Directions:
-
Students design and build a bridge between two books.
-
Test weight support by gradually adding small weights.
-
Evaluate how the design impacts the strength and brainstorm improvements.
Wrap Up with Purpose
These summer STEM activities keep students engaged, moving, and thinking. They’re flexible enough for summer school or a low-key classroom day in July. And with little prep and a few recycled supplies, you can keep the energy up without feeling overwhelmed.
STEM doesn’t stop just because school’s out. With the right mix of fun and learning, summer can be a chance to try something new, experiment, and build skills in a whole new way.
