This blog post provides a collection of fun and educational summer science experiments that will engage kids and spark their curiosity through hands-on activities.

Summer is the perfect time for kids to explore the wonders of science through fun and educational experiments. With the sunny weather and extra free time, children can dive into hands-on activities that spark curiosity and foster a love for learning. Here are some exciting summer science experiments that will keep kids entertained all season long.

Check out our blog, 7 Reasons to Encourage STEM Activities at Home, to learn more about the benefits of conducting fun and educational experiments. 

1. Solar Oven S'mores

Harness the power of the sun to make a delicious treat!

  • A pizza box
  • Aluminum foil
  • Plastic wrap
  • Black construction paper
  • Tape
  • Scissors
  • A ruler
  • Graham crackers, chocolate, and marshmallows
  1. Cut a flap in the lid of the pizza box, leaving one side attached.
  2. Line the inside of the flap with aluminum foil.
  3. Cover the opening with plastic wrap, securing it with tape.
  4. Place black construction paper at the bottom of the box.
  5. Assemble your s'mores and place them inside the box.
  6. Close the lid and adjust the foil-covered flap to reflect sunlight into the box.
  7. Place the solar oven outside in direct sunlight and wait for the s'mores to melt.

2. Rainbow in a Jar

Create a beautiful liquid rainbow and learn about density.

  • A tall, clear glass or jar
  • Honey
  • Corn syrup
  • Dish soap
  • Water
  • Vegetable oil
  • Rubbing alcohol
  • Food colouring
  1. Start by pouring honey into the bottom of the jar.
  2. Add a few drops of food colouring to the corn syrup and gently pour it over the honey.
  3. Next, carefully add a layer of dish soap.
  4. Colour some water and slowly pour it in, being careful not to mix the layers.
  5. Add the vegetable oil as the next layer.
  6. Finally, colour the rubbing alcohol and pour it on top.

3. Baking Soda and Vinegar Volcano

A classic experiment with an explosive twist!

  • Baking soda
  • Vinegar
  • Dish soap
  • Food colouring
  • A small container
  • Clay or playdough (optional for making a volcano shape)
  1. If desired, use clay or playdough to create a volcano shape around your container.
  2. Fill the container with baking soda.
  3. Add a few drops of food colouring and dish soap.
  4. Pour vinegar into the container and watch the eruption!

4. Egg in a Bottle

Learn about air pressure with this fascinating experiment.

  • A hard-boiled egg
  • A glass bottle with a mouth slightly smaller than the egg
  • Matches or a piece of paper
  1. Peel the hard-boiled egg.
  2. Light a match or piece of paper and drop it into the bottle.
  3. Quickly place the egg on top of the bottle opening.
  4. Watch as the egg gets sucked into the bottle due to the change in air pressure.

5. Ice Cream in a Bag

Make your own ice cream without a machine!

  • Half-and-half or milk
  • Sugar
  • Vanilla extract
  • Ice
  • Rock salt
  • Two resealable plastic bags (one quart-sized, one gallon-sized)
  1. In the quart-sized bag, mix half-and-half, sugar, and vanilla extract.
  2. Seal the bag tightly, removing as much air as possible.
  3. Fill the gallon-sized bag halfway with ice and add rock salt.
  4. Place the smaller bag inside the larger bag and seal it.
  5. Shake the bags vigorously for about 5-10 minutes.
  6. Enjoy your homemade ice cream!

6. Homemade Lava Lamp

Explore the science of liquids with this groovy experiment.

  • A clear bottle or jar
  • Water
  • Vegetable oil
  • Food colouring
  • Alka-Seltzer tablets
  1. Fill the bottle about a quarter full with water.
  2. Add a few drops of food colouring.
  3. Fill the rest of the bottle with vegetable oil.
  4. Break an Alka-Seltzer tablet into pieces and drop them into the bottle one at a time.
  5. Watch as the colourful blobs move up and down like a lava lamp.


These summer science experiments are not only fun but also educational, helping kids understand scientific concepts through hands-on activities. Whether it's harnessing solar energy, exploring density, observing chemical reactions, or learning about air pressure, these experiments will inspire young minds and create lasting memories. So, gather your materials, head outside, and embark on a summer filled with scientific discovery!
