3 Fun Science Experiments You Can Do at Home With Your Children

- - 0

Children of all ages mostly enjoy fun scientific experiments and activities. In this way, you can engage with your family on weekends or in the evenings after school. It’s also an excellent opportunity to understand scientific methods. A simple experiment could be the spark that makes them want to become scientists for the rest of their lives. Fun science experiments at home could be educational and entertaining for children of all age groups. However,  Science Tuition Harrow  came up with some interesting ideas to help children with science experiments. Thus, you’ll likely create some amazing project ideas for science fairs. So, we will introduce your child to the captivating world of Science through this article.

List of 3 fun Science Experiments

Each of these fun science experiments takes about 30 minutes from start to finish. They all use items from your kitchen. These stem challenges use everyday dish soap, food colouring papers, paper towels, white vegetable oil, baking soda, etc. Therefore, they introduce basic scientific concepts that your children will apply in school for many years.

1- Homemade Lava Lamp

Are you looking for a retro 70’s look? So, you can build your lava lamp at your home.


This one of the innovative, fun science experiments is popular with children ranging from 4- to 12 (and beyond!). It will also transport their most loved adults back to a few decades. Therefore, this science-based activity is easy to teach children about density.

What You Need:

  • A clean plastic bottle
  • Water
  • Vegetable Oil
  • Tablets that fizz 
  • Food Colouring


  • The bottle should be filled with water approximately 1/4 of the way.
  • Pour the vegetable oil into the bottle until it is about filled.
  • Use a funnel if you already have one. Take a moment and then watch the water and oil separate.
  • Add some drops of your preferred food colouring colour. The colour will make its move into the oil.
  • Next, cut your tab into half and drop a portion inside the container. The bubbles will form.
  • Turn off the lights and place them into a second-half tablet if you own the flashlight. So, use the flashlight to illuminate the lava lamp as the bubbles bubble!

What’s Happening?

The oil is floating over the water. Since it is lighter than water. The food colouring is a similar density to water. So, it can sink into the oil and liquid mixed with it. When the tablet dissolves, it releases a gas called carbon dioxide.

Thus, Gas is much lighter than water. It can float towards the top, adding some colour to colourants in food. If the water blob releases air that has coloured, it becomes heavier, and then it sinks.

2- Exploring Surface Tension (With Black Pepper)

Consequently, your children will be amazed by one of the best Fun Science experiments using pepper!


Surface tension is an essential scientific concept that even younger children can learn about. Therefore, this easy experiment using soap, water, and black pepper will have children enquiring about this important concept.

What You Need:

  • Black pepper
  • A bowl or plate
  • Water
  • Liquid soap


  • Cover your plate up with a fine layer of water. A little less than an inch is enough.
  • Sprinkle the pepper onto the surface of the water. Cover as a majority of the water’s surface as you can. The more pepper you have, the more enjoyable.
  • Then, dip your finger into the soap liquid. Therefore, make contact with the pepper and watch what happens!

What’s Happening?

The soap breaks the top tension in the water! Surface tension is present in water because water molecules tend to stick together.

The surface tension of water is high, which causes the molecules as they pull each other. They also stick to each other very firmly.

So, after the addition of soap, it breaks the surface tension. Ultimately, the molecules near the fingers get pulled back by those further far away.

3- Elephant Toothpaste


Have you heard about the elephant toothpaste experiment? It’s one of the best Fun Science experiments. All ages of children will be fascinated by discovering reaction catalysts, exothermic and catalysts through this fun and easy science experiment.

What You Need:

  • 16-oz plastic soda bottle
  • 1/2 cup 20-volume solution of 6% hydrogen peroxide liquid
  • 1 Tablespoon dried yeast
  • 3 Tablespoons hot water
  • Liquid dish soap
  • Food colouring
  • Small cup
  • Safety goggles


  • In the first place, wear safety glasses or eyewear that is protective. Hydrogen peroxide may irritate eyes and skin. To ensure safety, an adult must always be the person to put the hydrogen peroxide in the bottle.
  • The next thing to do is add eight drops of your preferred food colouring colour into the bottle.
  • Add one tablespoon of liquid dish soap. Shake the bottle around a mixture of the ingredients.
  • Mix the yeast and the warm water for 30 seconds in a separate container.
  • Then, add the yeast and water mixture into the bottle and observe the foam develop!

What’s Happening?

Every tiny bubble inside the foal contains oxygen. The yeast functioned as a catalyst to take the oxygen out of the hydrogen peroxide. Since it happened so quickly, it caused a large number of bubbles.

The bottle became hot because this is an exothermic process that produces heat. Thus, the foam is only of soap, water, oxygen, and water. So it is safe to dump it down the drain. Voila!

How to Triumph in Time Management for Online Learning


I hope these Fun Science experiments can quickly be done at your home. So, if you wish to make your child more imaginative and become a great scientist, try them. Students generally like different activities to explore in Science.
