October 8, 2026

STEM stands for science, technology, engineering, and math. And sometimes adding art turns STEM into STEAM. These disciplines give students opportunities to apply classroom learning to the real world, think critically, get creative, and solve problems through hands-on exploration.

National STEM Day is November 8, which makes it a great time to bring those skills together in your classroom. Whether you’re planning for the celebration or looking for STEM activities to use throughout the year, these ready-to-use Formative resources can help students design, build, test, analyze, and explore STEM careers.

Key Takeaways

  • Design and build: Students create solutions to hands-on challenges using a variety of materials and STEM concepts.
  • Test and improve: Students collect observations or data to evaluate their designs and make evidence-based improvements.
  • Choose the right challenge: Activities cover flight, structures, forces, data analysis, and other STEM concepts, so you can select one that fits your instructional goals.

Hands-on engineering challenges give students a reason to put STEM skills into action. In these activities, they’ll work through the engineering design process as they plan, build, test, collect evidence, and improve their designs.

[Explore circuits and robotics with STEM activities](id-circuits)

Key Takeaways

  • Build and troubleshoot circuits: Students test electrical setups, identify problems, and use evidence to determine how to fix them.
  • Design and program robots: Students work through the process of creating a robot for a specific task and reflect on each phase of their work.
  • Learn through testing: Both activities encourage students to apply STEM concepts by making something work, evaluating the results, and responding to what they discover.

Technology-focused STEM activities give students opportunities to learn by building, testing, troubleshooting, and programming. These two activities let students investigate how circuits work and apply robotics concepts to a design challenge.

Build and troubleshoot battery-powered circuits

Help students investigate what makes an electrical circuit work with the STEM Lab: Circuits with Battery-Powered Lights activity. They’ll build simple circuits, compare different circuit arrangements, and troubleshoot problems.

By the end of the lab, students should be able to explain what makes a circuit work, identify common faults, and use evidence from their testing to justify a fix.

Circuits Lab

Build a working circuit, then figure out what went wrong

Students progress from building a simple closed circuit to diagnosing and fixing circuit problems using evidence from their tests.

  1. 1 Light it up Build a simple closed loop that lights one section of battery-powered lights.
