Electrical and Construction STEM Projects for Students

Written by Staff Writer

A small bulb lights up. A paper tower stays standing. A seed begins to grow in a plastic bag. Each of those observations could be the result of someone asking a question, making a plan and testing an idea.

That is what STEM education is about — teaching people to have ideas and then test them. STEM stands for science, technology, engineering and mathematics, four subjects that often work together when students investigate problems and build solutions.

STEM projects help students build confidence, think through problems and learn from their results. Some activities work well in classrooms or with teams, while others can be completed at home with adult supervision.

Always follow the directions, use only the listed materials and never connect an electrical project to a wall outlet — use batteries instead.

Electrical Projects

Electrical projects explore how electricity moves through circuits and can be used to create light, heat or motion. Students may learn to identify conductors and insulators, trace a circuit, measure voltage and work out why a connection has failed.

Careful assembly, observation and troubleshooting are useful skills for people aiming to qualify as an electrician, electrical engineer or utility technician. As students grow older, these interests can lead to work with energy, power and fuel systems or to professional electrical skills training involving more advanced equipment.

Here are some example projects:

  • Paper Circuits: Light Up Exploded Stars and Constellations - Use paper, conductive tape, an LED and a small battery to make a low-voltage circuit that lights an astronomy picture.
  • Potato Battery Experiment - Turn a potato into a battery, test its electrical output and compare ways to increase the energy it produces.
  • Energy and Electricity Projects - Choose from projects such as wiring a simple circuit, building a flashlight, constructing a switch or making a small motor.
  • Snap Circuits - Use a snap-together kit to make circuits that light a bulb, spin a motor and compare series and parallel arrangements.
  • Solar S'mores - Design and test a cardboard solar oven to observe how sunlight can be captured and changed into heat.
  • Circuit Construction Kit: DC - Build virtual circuits, take voltage and current readings and compare series and parallel designs without handling physical components.

Engineering and Construction Projects

Engineering and construction projects challenge students to build something that meets a goal, such as a bridge that holds weight, a stable tower or a model house based on a scale drawing. Along the way, students learn about forces, balance, materials and the engineering design process.

They also practice sketching, measuring, estimating, teamwork and comparing the results of different designs. Related careers include architecture, civil engineering, construction management or serving as a mechanical maintenance technician. People in these jobs use drawings, measurements and tools to plan, build or maintain structures and equipment.

Try these symbol projects for a taste of what's involved:

  • 2D to 3D Truss Bridge Building - Construct a cardboard truss bridge within a set budget and test how much weight it can support.
  • Spoon Catapult - Combine craft sticks, rubber bands and a plastic spoon to build a lever that launches a small, soft object.
  • Tiny House Design - Use proportions and scale drawings to plan, build, evaluate and revise a model tiny house.
  • Paper Airplane Virtual Lesson - Fold two airplane designs, measure their wingspans and compare their flight times across several trials.
  • Paper Tower Design Challenge - Build the tallest free-standing tower possible using one sheet of paper and a limited amount of tape.
  • Electric Battery Car Competition - This middle-school challenge asks students to design, modify and race a battery-powered car while testing how design changes affect its performance.

Other STEM Projects

Other STEM areas include life sciences, earth science, environmental science, chemistry, computer science and physics. Students might grow a plant, examine a rock sample, create a model, write code or compare data. These activities help them observe carefully, make graphs, use digital tools and explain what their results show.

Possible career titles include biologist, geologist, environmental scientist, software developer, laboratory technician and instrumentation technician. When they are older, students interested in sensors and measurement can explore professional instrumentation skills training related to several of these disciplines.

Here's a selection of projects covering these areas. Be sure to arrange for adult supervision if using rubbing alcohol, sharp tools or live specimens.
