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.

Want to learn more about Circuits? Here is a great video from SciShow on YouTube.

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.

Why Should Students Learn How To Build Circuits?

This simple circuit project is a fantastic introduction to circuit building for kids. But why should kids learn how to build circuits? There are actually several reasons why it is beneficial for kids to learn how to build circuits. Let’s explore!

Project advisor

Information Gathering:

Find out about electricity and how it moves through conductive material. Read books, magazines or ask professionals who might know in order to learn about simple electric circuits. Keep track of where you got your information from. Save your life:

Imagine you are in a dark cave and you just lost your flashlight. Fortunately you do have a few spare light bulbs and a few spare batteries in your pockets. Can you use those and possibly one other metal object such as a spoon to light up a light bulb?

Each battery has two poles; each light bulb has two contacts. To light up a bulb you just need to connect the two poles of the battery to the two contacts of the light bulb using any conductive material. Conductive material such as metal forks, spoons, knives, wires, foils can easily be found. The picture on the right shows how you can use one piece of wire and a battery to light up a light bulb.

Remove the insulation from about 2 inches of each end of the wire; wrap one end over the screw contact of the light bulb and connect the other end to the bottom of the battery. Now place the light bulb over the battery in a way that the bottom contact of the light bulb will touch the top pole of the battery (positive pole). Your light bulb should be lit now. Can you use other conductive objects instead of the wire to do the same?

Question/ Purpose:

What do you want to find out? Write a statement that describes what you want to do. Use your observations and questions to write the statement.

The purpose of this project is to construct a simple electrical circuit to demonstrate that a circuit must have a complete path of conductive materials from one terminal of the power source through a load and back to the other terminal of the power source.

Following is a very important question related to this project.:

What household materials are conductive?

Identify Variables:

When you think you know what variables may be involved, think about ways to change one at a time. If you change more than one at a time, you will not know what variable is causing your observation. Sometimes variables are linked and work together to cause something. At first, try to choose variables that you think act independently of each other.

The status of a circuit (open or closed) is our independent variable. The flow of electricity that may light up a light bulb or activate any other electrical device is a dependent variable.

This means that the flow of electricity depends on the circuit open/ close status.

Hypothesis:

Based on your gathered information, make an educated guess about what types of things affect the system you are working with. Identifying variables is necessary before you can make a hypothesis.

My hypothesis is that there will be no flow of electricity when the circuit is open. We need to use wires to close a circuit so the flow of electricity from battery to light bulb and back to the battery can light up the light bulb. Since coin is a metal and metals conduct electricity, we can close a circuit using a coin.

Experiment Design:

Design an experiment to test each hypothesis. Make a step-by-step list of what you will do to answer each question. This list is called an experimental procedure. For an experiment to give answers you can trust, it must have a “control.” A control is an additional experimental trial or run. It is a separate experiment, done exactly like the others. The only difference is that no experimental variables are changed. A control is a neutral “reference point” for comparison that allows you to see what changing a variable does by comparing it to not changing anything. Dependable controls are sometimes very hard to develop. They can be the hardest part of a project. Without a control you cannot be sure that changing the variable causes your observations. A series of experiments that includes a control is called a “controlled experiment.”

Please Read Carefully!

All experiments use safe, low-voltage battery power. Household electrical current contains high voltage that could cause serious injury. Do not use household electrical current for any of these experiments.

Carefully follow wiring instructions for each experiment—improper wiring can result in battery leakage and/or rupture.

Do not take a battery apart—contact with internal battery material can cause injury.

Do not dispose battery in fire, recharge, put in backwards, mix with used or other battery types—may explode, leak and cause personal injury.

Making a Simple Electric Circuit

In this experiment you will make a Simple Electric Circuit. Please note that Simple does mean easy (in this context). It means an electric circuit with one battery, one lamp and one switch.

• Wood Board 12cm x 17cm (5″ x 7″)
• Single cell battery holder (MiniScience # MBH1D)
• Simple Switch (MiniScience # KSWITCH)
• Miniature lamp holder (MiniScience # MINIBASE, MINIBASEP, MINIBASEB)
• Miniature lamp 1.2-Volt (MiniScience # E0112)
• Small screws
• Connection Wires (Solid copper wires gage 20 up to 26 are recommended)

The picture bellow is from the Simple Electric Circuit kit of MiniScience.com.

Procedures:

1.Connect the battery holder, switch and the lamp holder to a piece of wood board using small screws. 2.Connect one wire from the battery holder to the lamp holder. 3.Connect one wire from the battery holder to the switch. 4.Connect one wire from the lamp holder to the switch. 5.Insert the battery in the battery holder.

6.Screw a lamp into the lamp holder. 7.Close the switch by lowering the lever. The light must turn on. 8.If the light does not work, check all the connections and try again.

You may not have access to battery holders, lamp holders and switches. In that case you may still be able to make a simple electric circuit. In this method we use thumbtacks, paperclips, clothespin, rubber band to substitute conventional materials such as switch, battery holder and lamp holder.

• Wind a bare wire end around a thumbtack. Hook a paperclip around the tack and press it into a wood block. Energizer.com – Learning Center – Science Projects – Steps
• Wind the second bare wire end around another thumbtack and press it into the wood.
• This wire will connect to the “Power Pack” positive (+) lead wire.
• Place a third thumbtack in the middle of the wood block to hold your paper clip switch in place. Your switch is now completed.

Alternate: Insulated knife blade switches are available commercially. You may purchase and use one of these switches for your experiment. Also insulated light bulb holders and small light bulbs are available commercially.

Build a Bulb Holder 5. Nail a clothespin to a wood block.

Energizer.com – Learning Center – Science Projects – Steps 6. Place a loose wire from switch (step #1) with a tack into the wood directly under the clothespin jaws. 7. Wrap one stripped end of the remaining unconnected wire around the bulb. Clamp it in the jaws of the clothespin with thumbtack below in order to make a complete circuit. 8. Tack the loose wire to the wood. This wire will connect to the “Power Pack” negative (-) lead wire.

Complete the Circuit 9. Take wire from step 3 and blend stripped end at right angle. Connect wire to positive (+) lead of the “Power Pack” with tape.

Energizer.com – Learning Center – Science Projects – Steps 10. Take wire from step 8 and bend stripped end at right angle. Connect write to negative (-) lead of “Power Pack” with tape.

When the circuit switch is open, the current does not flow to the bulb. With your finger, press down on the paper clip switch. You are closing and completing the circuit so the electricity can flow to the bulb. The switch, bulb holder, and portable power are a complete circuit and arrangement of conductors ; they allow the passage of electric current through the wire. Metal objects make the best conductors. Copper, brass, steel, or a strip of tin can have many free electrons capable of being moved along by an electromotive force such as voltage in the battery. In insulators, such as covering on the wire, electrons do not move easily, so you can work with electricity safely.

Conductivity Experiment

Introduction:

The simple electric circuit you have made can be used as a conductivity tester.

While the switch is open and the light bulb is off, place a coin between the switch contacts (thumbtack and paperclip). Does the light bulb turn on? If it does, the the coin is conductive.

Repeat this test with other household object such as nail, paper clip, metal spoon, plastic spoon, Popsicle stick, paper, aluminum foil and any other object you like to test.

Record your observations in a table like this:

Try to find about 10 or more objects that you can test them for conductivity.

Materials and Equipment:

This is a sample list of material:

• Wooden Base
• Miniature light bulb (1.2 volt, 2.5 volt, 5 volt)
• Miniature base (for light bulb)
• Insulated wire #23 (a few feet)
• Simple switch
• Battery holder

Electricity and Conductivity Science Set of MiniScience.com contains all the material listed above.

Completer list of material may vary depending on the experiments that you choose and the materials that are available to you.

Results of Experiment (Observation):

Experiments are often done in series. A series of experiments can be done by changing one variable a different amount each time. A series of experiments is made up of separate experimental “runs.” During each run you make a measurement of how much the variable affected the system under study. For each run, a different amount of change in the variable is used. This produces a different amount of response in the system. You measure this response, or record data, in a table for this purpose. This is considered “raw data” since it has not been processed or interpreted yet. When raw data gets processed mathematically, for example, it becomes results.

Calculations:

Write what did you learn from your experiments.

Summary of Results:

Summarize what happened. This can be in the form of a table of processed numerical data, or graphs. It could also be a written statement of what occurred during experiments.

It is from calculations using recorded data that tables and graphs are made. Studying tables and graphs, we can see trends that tell us how different variables cause our observations. Based on these trends, we can draw conclusions about the system under study. These conclusions help us confirm or deny our original hypothesis. Often, mathematical equations can be made from graphs. These equations allow us to predict how a change will affect the system without the need to do additional experiments. Advanced levels of experimental science rely heavily on graphical and mathematical analysis of data. At this level, science becomes even more interesting and powerful.

Conclusion:

Using the trends in your experimental data and your experimental observations, try to answer your original questions. Is your hypothesis correct? Now is the time to pull together what happened, and assess the experiments you did.

Related Questions & Answers:

What you have learned may allow you to answer other questions. Many questions are related. Several new questions may have occurred to you while doing experiments. You may now be able to understand or verify things that you discovered when gathering information for the project. Questions lead to more questions, which lead to additional hypothesis that need to be tested. Can you turn on a light bulb with just one wire? Can you turn on a light bulb without a battery or any other electrical source? Can you close a circuit using a coin?

Possible Errors:

If you did not observe anything different than what happened with your control, the variable you changed may not affect the system you are investigating. If you did not observe a consistent, reproducible trend in your series of experimental runs there may be experimental errors affecting your results. The first thing to check is how you are making your measurements. Is the measurement method questionable or unreliable? Maybe you are reading a scale incorrectly, or maybe the measuring instrument is working erratically.

If you determine that experimental errors are influencing your results, carefully rethink the design of your experiments. Review each step of the procedure to find sources of potential errors. If possible, have a scientist review the procedure with you. Sometimes the designer of an experiment can miss the obvious.

List of References

I was conducting an experiment to find out if I can get light from a grape or a fruit. I connected two D sized ever ready Battery together and used two alligator clips to connect the wire. I then connected the wire to the fruit and used the tester to see if it will light up but it did not light up. I disconnected the batteries form the fruit and added two more batteries together. I used the tester to test how powerful the four batteries were together and the tester lighted up for a while and then it blew. I then opened the tester and found out that the bulb inside the tester appeared to be the same as those of Christmas lights. I will like to know why the tester did not light up when I had the batteries connected to the fruit.

I am not sure that I understood your question; so, I rephrase it and then answer.

You are using the battery as a source of electricity and using grape as a light bulb and you want to light up a grape. If this is what you are trying to do, it is impossible. Grape and other fruits cannot produce light.

Your project is making electricity from fruits. In other words you want to make a potato to work as a battery. So instead of using battery to light up a light bulb, you want to use a potato to light up a light bulb. This may be possible. I say maybe because if the amount of electricity that you produce is too low, it will not be enough to light up any light bulb.

In this case you may use a voltmeter to show that your fruit is actually producing some electricity.

It is always important for students, parents and teachers to know a good source for science related equipment and supplies they need for their science activities. Please note that many online stores for science supplies are managed by MiniScience.

25 Electricity Experiments For Kids

By Beth Roberts | Last Updated April 21, 2022

It’s hard to get kids excited about science and experiments. But luckily, there are plenty of cool ideas for electricity experiments for kids that you can use to change that.

Take a look at these 25 unique science projects for kids about electricity, perfect for all ages and skill levels. You will find some easy, quick experiments that take more time and preparation. So try something new this summer.

1. Waterbending Static Electricity Experiment 

The kids want to know what they can do with the electricity they get from their hairdryers, and that’s a good question. Can they turn it into the water? Can they create an electrical field and make water? The answer is yes! Follow this simple step-by-step guide to see how to do it. This experiment is fun for all ages, but children will enjoy playing with this stuff the most.

2. Make a Magic Wand 

You probably know about static electricity. It’s what causes the hair to stand up on your arms and the hair dryers to get hot. But did you know that you can use that static electricity to create a magic wand ? Kids will love learning how magnets work and how to make them work together.

3. Index Card Flashlight Experiment

Do the kids want to know how light works? It turns out that light is created by electricity and magnetism . In this easy experiment, the kids will learn about the basic principles of light using just a little bit of aluminum foil.

4. Potato Clock 

Potato Clock is a cute little science experiment that will teach kids how electricity and magnetism work together to create a clock. The potato is the clock face; the paper is the hands; the pen is a needle, and the magnets are the wind-up key. The kids will love making this clock, and they can even make it into a working toy if they choose to.

5. Bubble Balloons 

This experiment is a blast for all ages. The kids will learn how to make a bubble balloon and then how the bubble balloon becomes energized by electricity and magnetism when they touch it together!

6. Soda Can Electroscope 

There are two basic ways that the human brain sees movement. One way is through color and light; the other is sound and vibration. Both of these ways are important to us as humans but at different levels of importance. If you think about it, when you see a person, they have a face or a walking motion. But when you see something move in the dark or a mirror, it can be almost unrecognizable to you.

7. Create a Motor 

Creating a Motor is a great experiment to show kids how electricity works. They will learn about magnets and how they work to create motion in a simple motor. You will need some paper, a drawing, and a wire. You can make one for yourself or build one for your child.

8. Build a Power Pack

Build a Power Pack is an easy experiment that shows kids how electricity and magnets work together to create motion. They will need a paper clip, some aluminum foil, and some tape. Building a Power Pack is a fun, easy, and cheap way to teach kids to develop their primary electrical circuits. You can do this too! You will need some components. 

9. Bottle Radio 

You can make a bottle radio out of aluminum foil if you have a lot of it. The kids will love looking at the different sounds that come out of the bottle, and they may even be able to learn some science along the way.

10. Making a Dimmer Switch 

Making a Dimmer Switch is another way to process electricity that always makes me smile. When the kids make a dimmer switch, they will learn how magnets work together to create motion and light. They can then use this knowledge to create their electromagnets!

11. Separate Salt & Pepper 

Separate Salt & Pepper scientific project only requires a battery and some salt & pepper. Pour the salt and pepper into separate containers and place the mortar between them. This works because storms cause the electro-central place of batteries atoms in this works. The particles in each article are attracted to the end of the storm.

12. Butterfly Experiment  

A butterfly may seem like nothing more than a pretty winged insect. But when you use electrical charge and light, you can use a butterfly to demonstrate how electricity moves around the world. The easiest way to do this is with the double-sided 4x4x4 L.E.D. Cube and a single L.E.D. that has four sections of equal lengths. Simply connect one cube side up, then place the other cube side down on top of it.

13. Homopolar Motor 

Homopolar motors work by using electricity and magnets . They involve spinning a magnet at high speeds. A small wheel to propel the interest if the magnetic field is strong enough.

14. Build an Electromagnetic Train 

Electromagnetic trains are a great way to investigate the properties of electromagnetism. If you have no experience with this kind of science project, you can still make your own. Only a few everyday home items and some patience are required. First, make sure that the track will be smooth and even. Next, find a material that can conduct electricity well and put it on the way so that it won’t be too small or big.

15. Electric Cornstarch 

Electric cornstarch is a great way to prove that cornstarch can conduct electricity. You have to make a plastic glove by cutting the top off a bottle and filling it with cornstarch. Then, charge one end of the plastic glove with electricity, and the other side will light up.

16. Water & Electricity 

Water is famous for its ability to conduct electricity. It was demonstrated in this project when in a clear glass bottle with two different electrolytes. The two electrolytes were saltwater and pure vinegar. The only difference was that one contained salt while the other contained vinegar when the saltwater with electricity becomes an electrolyte using a voltmeter.

17. Steady Hand Game 

Who knew a battery, a tiny bit of metal, and two wires could provide so much entertainment? After the cables are attached to the battery and the metal, place one on each side of your hand. You will feel an electrical vibration that will make it hard for you to keep your hand steady.

18. Tiny Dancers (Homopolar Motor) 

Homopolar motors are fun and easy to make. And they are also known as tiny dancers because they tend to spin around in circles. This is a great beginner project for learning about electricity, but it does require some items that you may not have lying around the house. So double-check the list before you begin!

19. Simple Lemon Battery

Simple Lemon Battery particular fun experiment has so much to offer because it is one of the most basic. But it still proves electricity is natural and how a battery works. In short, all you need are a lemon, two nails, and an alligator clip. Then, attach one pin to the opposing end of the battery and the other nail to the positive end. Finally, put the middle of each nail into a lemon half.

20. Rising Ghosts Experiment 

A motion source creates electromagnetic fields . Then, they will attract electrons to it and make an electric field that acts as an antenna. In this project, you will charge a ghost with electricity, and then you will be able to see the ghost move, but it won’t be floating.

21. Play Dough Circuits 

Play Dough Circuits is a straightforward project that makes it easy to see what happens in a circuit without going with the big guns of building a complete course. One course consists of two conductive rods and polystyrene balls. You can use whatever materials you have around the house–including play dough!

22. Copper Plate Coin 

Use a pen going to complete a circuit and light up some L.E.D.s! It is such a fun project for kids as it is easy to set up and does not require much work–or even very many materials, for that matter. And look at how cool the lights shine through when you hold the copper plate above them!

23. Dirt Battery Experiment 

Dirt Battery Experiment is a fun activity that shows kids how batteries work. You need to prepare a half cup of copper sulfate and dish soap–and then mix it all up (using your hands). Then, add half a cup of salt and another cup of warm water. It takes about five minutes to put up, and your kids will have a fun science experiment to show off to their friends.

24. Rainbow Salt Circuit 

Rainbow Salt Circuit is an excellent , colorful project that your kids will love to do. It uses liquid crystals and salt to make a circuit that lights up when pouring in the salt. Rainbow Salt Circuit  can be adapted to suit any age and is one of the best easy experiments for kids

25. Homemade Wigglebot 

Homemade Wigglebot is a fun project that looks like a face but acts like an actual robot! This requires very few materials, so it is an excellent science experiment for kids. The Wigglerbot in a straightforward way–just some wooden craft sticks and plastic tubing. Simply attach the tubes to the tips of the wooden craft sticks, as this creates a circuit.

Easy Electricity Projects for Kids

May 19, 2021 By Emma Vanstone Leave a Comment

Electricity and circuits are great fun for children ( and teachers and parents ) to learn about. This collection of electricity science projects and experiments are all easy to try and very satisfying. Watching a bulb or an LED light up because a circuit works always seems very rewarding, and the bonus is you can be as creative as you like! Make houses, torches, robots, and so much more. The creative opportunities with this kind of STEM project are endless!!

These electricity experiments use only a battery so they are safe if supervised by an adult. Remember, mains electricity is very dangerous.

Please supervise children with these activities at all times.

Quick electricity and circuit refresher

Electric current is the flow of charge around a circuit , it can only flow if the circuit is complete.

A battery acts like a pump, pushing the electric charge around the circuit. We call this force voltage. The higher the voltage the more current flows.

You can increase voltage by using multiple batteries or higher voltage batteries.

Which materials conduct electricity?

Metals conduct electricity as they allow electrons to pass through them. Electrical charge is a flow of electrons ( negatively charged particles ).

The opposite of a conductor is an insulator. Insulators don’t allow electric charge to pass through them. Plastic, wood and glass are examples of insulators.

What conducts electricity other than metals?

Sea water or a homemade salt solution. Teach Engineering has instructions for a great salt water battery .

Graphite – see our graphite circuit below.

Do you have any more electricity project ideas for us to try?
