Electric Circuits for Kids

Electricity is a vital and key part of our daily lives. It is all around us, everywhere we go, transforming everything we do. So it is important that kids are given a solid foundation in electrical engineering projects. Today we are learning how electrical circuits work with lots of innovative hands on project ideas.

Learning about electricity and circuits is an important part of a child’s education. Depending on where you live, learning about electricity can start as early as Grade 4 but often is covered more extensively in more advanced physics classes. As part of their electrical engineering studies students should learn the physics of circuits, which is best done with hands on experiments. This drastically improves understanding of these concepts rather than relying on memorization. So let’s dig into some fun hands on learning with electricity experiments.

What is a Circuit?

First we should start with the basics, What is a Circuit? When it comes to STEM projects, an electric circuit is a complete circular path that electricity flows through. A simple circuit consists of:

  • a current or energy source like a battery,
  • conductors which are often wires, but we have a few experiments that use innovative materials as conductors,
  • a load which could be an LED light bulb or a buzzer or a fan.

Electrical Safety with Kids

Whenever we are working with electricity is very important that safety is part of the lesson and discussion with kids. Although these simple circuits with small charges are quite safe, students need to understand that electricity and electrical wires can be very dangerous. Never do any circuit projects with a child unless they are mature enough to behave safely and appropriately while working with electrical circuits.

Classroom Circuit Project Supplies and Tools

A great thing to build for your classroom is a circuit kit which includes basic supplies for doing the majority of circuit projects. Many of these supplies and tools can be reused over and over again for future circuit projects and classes.

Wires with alligator clips
Battery holder
Battery cases with on/off switches
LED diode light bulbs
Small motors and accessories
Zinc and Copper Strips
Copper Tape
Soldering Iron (for high school students doing advanced projects)
Plus recyclables such as TP rolls, cardboard, craft paper, craft sticks, etc.

Now we have chatted about circuits, let’s get busy with some hands on circuit making projects!

Building Batteries with Food

Did you know you can capture the energy of food and use it to power a light bulb? Building food batteries is a great project to do with the kids. Not only do they learn more about the foods that they eat, but they are also learning about circuits, how batteries work, and these projects have a BIG WOW moment as that light bulb lights up!

Lemon Battery

First, we have a lemon battery. This is a very easy project and a great one to get started with the kids on learning about electricity.

Pumpkin Battery

Next up, try making a pumpkin and squash battery. This is a fantastic fall project, and you can use your pumpkins to make batteries before you carve them.

Potato Electricity Experiment

For your older students who are looking for a bigger challenge, try making Potato Batteries. This is actually something scientists are studying as a possible energy source.

Now we have introduced you to the idea of making a battery out of foods, what other foods do you think you could make a battery from?

Simple Circuit Projects and Experiments

Glow Salt Circuit

A very simple circuit you can make with kids is a salt circuit. But we couldn’t just make a simple salt circuit, we powered it up by making a Glow Salt Circuit. We loved the activity so much we also make a Valentine’s Day Heart Circuit and a Christmas Tree Glow Circuit. All using the same concept and a little creativity.

Rainbow Salt Circuit

This activity was the very first salt circuit we ever made. It combines beautiful colours into a simple beginner circuit project.

Squishy Circuit Pumpkin

Another fun circuit project to do with kids is to make Squishy Circuits. In this project we made a fun Halloween Pumpkin Squishy Circuit which included making our own conductive and insulating doughs from scratch.

Squishy Circuit Anglerfish

Another version of the Squishy Circuit uses modeling clay and playdough, all easily bought at the store or probably already in your classroom supplies. So easy and so much fun!

TP Owl Circuit Craft

Here at STEAM Powered Family we LOVE owls! In this circuit project we made an Owl Craft out of a toilet roll, then powered it up with a simple circuit making project that lights up its eyes.

Mummy and Bat Circuit Craft

For Halloween we took our Circuit Owl STEM Craft and created a Bat Circuit Craft and a Mummy Circuit Craft. Spookily perfect!

Easter Glow Candy Jar

In this circuit project we are exploring paper circuits to light up a beautiful candy jar for Easter. You can easily adapt this design to any holiday season or just because you want a gorgeous candy jar that lights up!

Olympic Torch Circuit Craft

This simple Olympic Torch Craft is a great project to do with the kids to celebrate the Summer and Winter Olympics.

Advanced Circuit Projects

Once you have mastered simple circuits, why not tackle something a little more challenging?

Lumos Wand

In this project we are creating a special wand inspired by the Harry Potter stories. This wand includes a special homemade on/off switch so your witches and wizards can cast Lumos and Nox!

Circuit Bugs

Way back when STEAM Powered Family was just starting, one of the very first activities we shared was Circuit Bugs. This was a project we loved creating as a family and went on to become one of the most popular Circuit STEM activities on this site.

Circuit Flowers

Combine chromatography and circuits in this STEAM activity where you create the most beautiful glowing flowers.


This is a festive Christmas tree twist on the popular Circuit Bugs and Circuit Flowers activity.

Buzz Circuit Game

For your teens that are looking for a really cool challenge or something they could build for a STEM competition or STEM fair, the Buzz Circuit Game is perfect! It is basically a homemade version of the popular Operation game. So cool!

Snap Circuits

One of our favourite ways to explore circuits for young and old is Snap Circuits. There are kits for all different types of interests and passions. My kids simply love exploring with their Snap Circuit sets. It is always out and ready to go in our tinkerspace.

Creation Crate

For kids that are looking for more of a STEM curriculum to do at home, Creation Crate is the solution. Kids not only learn about circuits and electrical engineering, but they also learn coding. The boxes gradually increase in difficulty, so kids can build their skills and knowledge with each new box.

Have a blast exploring with circuits!
