This page includes games for groups of 1 to 100 and experiments that range from no-supplies-needed to do-it-yourself supplies.

Electricity Group Game

Summary: Squeeze your teammate’s hand as quickly as possible- only if the coin comes up as heads!

Goal: Be the first team to grab the object, if the quarter comes up as heads.

– A quarter
– An object for teams to grab (ball, stuffed animal, water bottle, etc.)

How to Play Electricity:
1. Arrange everyone into two equally numbered teams. Have both teams line up in parallel lines. At the end of the line, place the object about five feet away (in equal distance from both ends of the line). You’ll be at the head of the line.

2. Explain the rules: Everyone in line will need to hold hands and close their eyes. Only the first person of both lines can open their eyes. Flip the coin in the air, catch it, and reveal the quarter to the first person of both teams.

3. If the quarter comes up as “heads”, the first person squeezes the next person’s hand. The second person squeezes the next person’s hand, and so forth. At the end of the line, the last person runs to grab the object. The team that grabs the object first wins a point for the round. If the quarter comes up as “tails”, then no one squeezes anyone’s hand. If there’s an “accidental” hand squeeze and the quarter comes up as “tails”, the team that grabbed the object loses a point for the round.

4. For the second round, the first person goes to the back of the line and the game continues. The first team that reaches 10 points wins the game.

Use a magnetic field to make a simple motor!

Material List

  • 1 - AA Battery
  • 1 - Pack Neodymium Disc Magnets
  • 1 - Copper Wire (about 20 cm)


  1. Stack the magnets on the negative side of the battery (flat side) and place it on the table.
  2. Bend the copper wire into a heart shape.
  3. Place the point of the heart on the positive end of the battery.
  4. Adjust it so that the ends of the wire lightly touch the magnets.
  5. Watch it spin!
  6. Once you get the hang of it try other shapes!

How It Works

The electric current from the battery flows through the wire, generating a magnetic field. The field from the magnets interacts with the magnetic field from the wire. This applies a force on the wire which causes it to move. Scientists call this design a homopolar motor.


DIY Solar Oven

You don't need electricity to cook your food when you can harness the power of the sun.

What You Need:

  • Cardboard pizza box (the kind delivered pizza comes in)
  • Box knife or scissors
  • Aluminum foil
  • Clear tape
  • Plastic wrap (a heavy-duty or freezer zip lock bag will also work)
  • Black construction paper
  • Newspapers
  • Ruler or wooden spoon
  • Thermometer


  1. Use a box knife or sharp scissors to cut a flap in the lid of the pizza box. Cut along three sides, leaving about an inch between the sides of the flap and the edges of the lid. Fold this flap out so that it stands up when the box lid is closed.  
  2. Cover the inner side of the flap with aluminum foil so that it will reflect rays from the sun. To do this, tightly wrap foil around the flap, then tape it to the back, or outer side of the flap.
  3. Use clear plastic wrap to create an airtight window for sunlight to enter the box. Do this by opening the box and taping a double layer of plastic wrap over the opening you made when you cut the flap in the lid. Leave about an inch of plastic overlap around the sides and tape each side down securely, sealing out air. If you use a plastic bag, cut out a square big enough to cover the opening and tape one layer over the opening.
  4. Line the bottom of the box with black construction paper—black absorbs heat. The black surface is where your food will be set to cook. How much you need will depend on the size of the pizza box you're using to make your solar oven.
  5. To insulate your oven so it holds in more heat, roll up sheets of newspaper and place them on the bottom of the box. Tape them down so that they form a border around the cooking area. It may be helpful to also tape the rolls closed first. The newspaper rolls should make it so that the lid can still close, but there is a seal inside of the box, so air cannot escape.
  6. The best hours to set up your solar oven are when the sun is high overhead—from 11 am to 3 pm. Take it outside to a sunny spot and adjust the flap until the most sunlight possible is reflecting off the aluminum foil and onto the plastic-covered window. Use a ruler to prop the flap at the right angle. You may want to angle the entire box by using a rolled-up towel.
  7. You can make toast by buttering a slice of bread then letting the sun do the rest. Cooking a hot dog or making nachos with chips and cheese are also fun treats to make in your solar oven! It would also work great to heat up leftovers. So the paper at the bottom doesn't get dirty, put what you would like to cook on a clear plastic or glass plate. A pie plate would work well. Place the thermometer inside your oven before you close it, so you can check the temperature.
  8. To take food out of the oven, open up the lid of the pizza box, and using oven mitts or potholders, lift the glass dish out of the oven.

What Happened:

The heat from the sun is trapped inside of your pizza box solar oven, and it starts getting very hot. Ovens like this one are called collector boxes because they collect the sunlight inside. As it sits out in the sun, your oven eventually heats up enough to melt cheese, or cook food!

How does it happen? Rays of light are coming to the earth at an angle. The foil reflects the ray and bounces it directly into the opening of the box. Once it has gone through the plastic wrap, it heats up the air that is trapped inside. The black paper absorbs the heat at the bottom of the oven, and the newspaper makes sure that the heat stays where it is, instead of escaping out the sides of the oven.

Your solar oven can reach about 200° F on a sunny day and will take longer to heat things than a conventional oven. Although this method will take longer, it is very easy to use, and it is safe to leave alone while the energy from the sun cooks your food.

If you do not want to wait long to have a solar-cooked dish, try heating up something that has already been cooked, like leftovers, or a can of soup. Putting solid food in a glass dish and liquids in a heavy plastic zip lock bag works well. You can also pre-heat your oven by setting it in direct sun for up to an hour.

Static Electricity Experiment

They say opposites attract and that couldn't be truer with these fun static electricity experiments. Find out about positively and negatively charged particles using a few basic items. Can you control if they will be attracted or unattracted to each other?


What you'll need:

  • 2 inflated balloons with string attached
  • Your hair
  • Aluminum can
  • Woolen fabric



  1. Rub the 2 balloons one by one against the woolen fabric, then try moving the balloons together, do they want to or are they unattracted to each other?
  2. Rub 1 of the balloons back and forth on your hair then slowly pull it away, ask someone nearby what they can see or if there's nobody else around try looking in a mirror.
  3. Put the aluminum can on its side on a table, after rubbing the balloon on your hair again hold the balloon close to the can and watch as it rolls towards it, slowly move the balloon away from the can and it will follow.


What's happening?

Rubbing the balloons against the woolen fabric or your hair creates static electricity. This involves negatively charged particles (electrons) jumping to positively charged objects. When you rub the balloons against your hair or the fabric they become negatively charged, they have taken some of the electrons from the hair/fabric and left them positively charged.

They say opposites attract and that is certainly the case in these experiments, your positively charged hair is attracted to the negatively charged balloon and starts to rise up to meet it. This is similar to the aluminum can which is drawn to the negatively charged balloon as the area near it becomes positively charged, once again opposites attract.

In the first experiment both the balloons were negatively charged after rubbing them against the woolen fabric, because of this they were unattracted to each other.

Learn how to make a battery out of coins to power an LED!

Material List

  • 1 - Teaspoon of salt
  • 1 - Cup of water
  • 1 - Red LED light
  • 6 - Pennies
  • 6 - Zinc washers
  • 1 - Bowl of ¼ Cup of Vinegar
  • 1 - Piece of Construction Paper
  • 1 - Pen
  • 1 - Pair of scissors


  1. In a bowl, mix 1 teaspoon of salt into ¼ cup of vinegar.
  2. Soak the pennies in the salt/vinegar mixture for 5 minutes, then wipe them off.
  3. Trace pennies on construction paper and cut them out to make 6 paper discs.
  4. Soak the paper disks for 5 min in a mixture of 1 cup of water and 1 tablespoon of salt.
  5. To assemble the battery, stack the items in this order: coin, paper, washer, coin, paper, washer, and so on.
  6. Hold the LED light’s long wire to the penny side of the stack, and the short wire to the zinc side of the stack.
  7. Dim the light and your LED should light up!

How It Works

In this DIY you made a battery! Batteries convert chemical energy into electrical potential energy. That energy can be used to power a circuit, or in our case, an LED light. The more stacks there are, the higher the voltage of the battery and the brighter the light will be. The difference between a 1.5-volt battery and a 9-volt battery is how many stacks of chemicals they have inside.
