How High School Students Can Teach STEM to Elementary Students

Elementary students learn fastest by doing. Open with a hands-on challenge, such as building a simple circuit, a paper structure, or a small program, rather than a long explanation. Introduce the concept after they have tried it.

Give one instruction at a time and show it as well as saying it. Replace jargon with everyday words, and introduce one new term at a time. Check understanding by asking a student to explain the step back to you.

Groups of two to four keep everyone involved and let you circulate. Give each group member a job, such as builder, tester, or reporter, and rotate roles so every student gets to handle the activity.

Keep an adult in the room, choose age-appropriate materials, and set clear rules for tools and supplies before you start. STEM Sprouts recommends adult guidance for all of its curriculum activities.

Good lessons fit their setting. Pinboard lets students practice Arduino and Raspberry Pi circuits virtually, which helps when physical kits are limited. The STEM Sprouts chapter in Siaya, Kenya, builds its programs offline-first because many rural schools lack reliable power and internet, a reminder to always have a plan that works without them.

• Test every activity beforehand with the same equipment you will use.
• Bring a simpler backup activity.
• Reuse and adapt lesson plans from previous sessions instead of starting from scratch.

When a circuit does not light up or a program does not run, treat it as the interesting part. Ask students what they think went wrong and let them troubleshoot. Celebrating persistence builds the confidence that keeps younger students interested in STEM.
