STEM Projects by Grade

Choose a project that helps learners build, test and explain an idea. These are Electroys curriculum matches, not teacher endorsements; check your school syllabus and each maker's age guidance.

Pre-K–Grade 2

Build and give directions

Assemble a simple moving model or plan a path one step at a time. Ask learners to explain what changed when their first attempt did not work.

Project picks: Kids First Robot Engineer (3+), Kids First Coding & Robotics (4+), Code & Go Robot Mouse (5+).

Before buying: Small parts, adult help, group size and screen-free instructions.

Grades 3–5

Test circuits and energy

Build two circuit designs or test how a device converts energy. Compare what works, record the result, then improve the design.

Project picks: Snap Circuits Beginner (5+), Snap Circuits Junior (8+), Solar Science Station (Grade 4+).

Before buying: Reusable parts, enough pieces for groups and a clear test-and-revise lesson.

Grades 6–8

Investigate motion and robotics

Build a vehicle, change one variable such as surface or route, and measure the result. Introduce sensors and code when the class is ready.

Project picks: LEPANDA RC Robot Car (8+), Makeblock mBot2 (8+), Edison V3 (check maker guidance).

Before buying: Assembly time, replacement parts, device compatibility and measurable outcomes.

Grades 9–12

Prototype and explain tradeoffs

Program a sensor-driven prototype, collect data and justify design choices against cost, reliability and other constraints.

Project picks: Arduino Student Kit, SparkFun Inventor's Kit, Makeblock mBot Ultimate.

Before buying: Programming prerequisites, documentation and full classroom cost.

Planning references: NGSS and CSTA computer science standards. Match activities to your district's requirements. Product links and availability should be checked before purchase.
