STEM (Science, Technology, Engineering, and Mathematics) education is an exciting way to engage students with real-world applications. It sparks creativity, critical thinking, and problem-solving skills, which are essential for today’s fast-paced, technology-driven world. For middle and high school teachers, integrating STEM into science lessons can create hands-on learning experiences that bring abstract concepts to life.
To help you get started, I’ve compiled 30 STEM activity ideas for your classroom. These activities are perfect for earth science, environmental science, biology, and more. Plus, be sure to check out the free list of comprehensive STEM activity ideas.
How to Incorporate STEM into Your Science Curriculum
Incorporating STEM into your science lessons doesn’t have to be a huge overhaul of your current plans. Instead, try embedding these activities naturally into the topics you’re already teaching. By encouraging students to experiment, design, and apply their learning in creative ways, you help them see the real-world relevance of science. Here are some great ways to do just that:
1. Build and Test Water Filtration Systems
This hands-on activity allows students to design their own water filtration systems using sand, charcoal, and coffee filters. It’s an excellent way to explore concepts in environmental science, such as the importance of clean water and the processes that remove contaminants. Students will test the effectiveness of their filters by evaluating the clarity, pH, and other contaminant levels of the filtered water.
Pro Tip: Tie this activity into lessons on pollution, ecosystem health, and the global water crisis.
2. Design Earthquake-Resistant Buildings
Students will use dry spaghetti noodles and marshmallows to design and test earthquake-resistant buildings. They will test their designs and make improvements based on observed data. This activity introduces basic engineering principles, material science, and data analysis.
Pro Tip: Integrate this activity after a lesson on plate tectonics and how earthquakes form. Challenge students to consider the geography of the locations they’re designing for.
Want to take earthquake engineering to the next level? Check out my brand-new Quake-Proof Tower Challenge! In this hands-on STEM challenge, students will design and build a tower that can withstand simulated earthquakes. They’ll apply engineering and physics concepts while putting their designs to the test on a shake table. This activity is perfect for getting students excited about structural engineering and real-world problem-solving!
3. Oil Spill Simulation and Cleanup Challenge
Incorporating real-world environmental challenges into your STEM activity can make lessons more impactful and engaging for students. One popular hands-on activity is the Oil Spill Simulation and Cleanup Challenge. In this experiment, students simulate an oil spill in a water-filled container and test different cleanup methods using materials like cotton balls, sponges, and dish soap. They analyze the effectiveness of each method and reflect on the environmental and economic impacts of oil spills.
This activity is perfect for sparking discussions about sustainability, engineering solutions, and environmental science. Need a ready-to-use version?

4. Design an Eco-Friendly City
In this collaborative project, students work in teams to design an eco-friendly city that incorporates renewable energy sources, sustainable transportation, and green building practices. They’ll calculate the environmental impact of their designs, making this an excellent lesson in sustainability and urban planning.
Pro Tip: Encourage students to research existing green cities around the world for inspiration and create presentations to share their innovative solutions.
5. Explore Crater Formation with Impact Simulations
By simulating asteroid impacts with marbles, flour, and cocoa powder, students can visualize how craters are formed. This simple yet engaging experiment allows students to manipulate variables like height, angle, and object size to see how they affect crater formation.
Pro Tip: After the activity, discuss how scientists use impact craters to understand the history of our solar system.
6. Build Solar-Powered Cars
In this activity, students design and build a small solar-powered car. They race their cars, calculating how much energy their design captured and how effectively it converted that energy into motion. This is an excellent introduction to energy concepts, solar power, and renewable technologies.
Pro Tip: Have students work in pairs or groups, encouraging collaboration and testing different materials to maximize their car’s performance.
7. Investigate Solar Energy and Solar Panels
This hands-on activity has students design a small solar panel system to power a simple device. They test the efficiency of different materials and angles to understand how sunlight is converted into energy. It’s a great way to explore the science behind solar energy and sustainable technology.
Pro Tip: Extend the lesson by asking students to calculate how much energy their panels would produce over a day, week, or month, and compare it to energy needs in their own homes.
8. Waste Reduction Challenge
Students will design a system to reduce waste in their school or community, such as creating a composting program or reducing single-use plastics. They’ll analyze the environmental impact of their projects and track the results over time. This challenge is a great way to discuss sustainable practices and the importance of waste management.
Pro Tip: After the project, encourage students to create awareness campaigns to educate their peers about waste reduction.
9. Bridge Design Challenge
Challenge students to design and build bridges using materials like popsicle sticks or spaghetti. They’ll test their bridges by applying weights and analyze the strength-to-weight ratio to evaluate the performance of their designs.
Pro Tip: Relate this activity to the principles of physics, such as tension, compression, and forces, and challenge students to innovate with new materials or designs.
10. Making Slime
In this fun activity, students create slime from simple ingredients like borax and glue. This experiment allows students to explore the properties of polymers, chemical reactions, and how varying ingredient ratios change the consistency of the slime.
Pro Tip: Discuss the real-world applications of polymers, such as in packaging, medicine, and everyday products.
Why STEM Matters
Incorporating a STEM activity into your science lessons encourages students to engage actively in their learning, promote collaboration, and foster critical thinking. These activities also offer a chance to incorporate real-world problems and challenges into the classroom, making lessons feel relevant and exciting. Whether you’re teaching earth science, environmental science, or any other science subject, STEM activities help students see the practical applications of what they’re learning while honing essential skills for the future.
