The Best Science Experiments For Kids

Published on 28th September 2020 by Tessa Robinson

Is your child interested in science? Would they like to try their own science experiments for kids at home? Here at Club Hub, our directory is filled with thousands of science classes for kids, so we have spoken to a few providers to tell us a bit more about their businesses and their recommended science experiments for kids to try themselves. Remember to ask for adult permission/supervision. “Science Experiments for Kids” 

Amanda Childs, Founder of Sparking STEM

Science Experiments For KidsChildren learn best when they can find things out for themselves. At Sparking STEM, we believe a good science experiment for kids should firstly grab their attention, making them question what they see. Now they’re engaged, set a challenge to support them to answer those questions with experience. Finally, consolidate by testing their ideas with further experimentation.

Here’s a simple and fun science experiment for kids to learn about how gases expand and contract with changing temperature:

  1. Stretch the mouth of a completely empty balloon over the open top of a rigid bottle.
  2. Lower the bottle into hot water. The balloon should expand as the air particles gain energy and move further apart to fill the balloon. 
  3. Challenge them to deflate the balloon without touching it (place in cold water but let them work it out)!
  4. Experiment with different temperatures, in the sun, in the fridge, record the data… 
  5. Let their curiosity take the lead!

About Sparking STEM

Sparking STEM works alongside schools, universities and other educators to spark enthusiasm for science, technology, engineering and mathematics (STEM) in young people from preschool to A level, and supports and trains others to do the same.

Sparking STEM offers weekly Online STEM sessions: Interactive and curriculum-linked, these small group sessions provide tuition in STEM subjects for students aged 5 to 15. Children join in with experiments and activities at home; watch live science demonstrations and learn by doing, predicting, questioning and problem-solving, whilst having lots of fun! The small group meeting format allows students to interact fully or observe anonymously, so that they can learn and enjoy however they feel most comfortable.

Science Experiments For Kids

Our exciting Outdoor STEM and Practical Support for iGCSE Science sessions are available in Sheffield (when the current situation allows) during term time, as well as 1:1 and small group science tuition, (online and face to face).

Genie Lab Science – Cinderella’s Task – Science Experiments for Kids

Science Experiments For KidsPoor Cinderella has been given the menial task of separating salt from pepper…She’s going to need a miracle! Challenge your friends to do the same and we will tell you how to win!

Sprinkle about a teaspoon of salt and pepper as randomly as possible onto a plate. Now blow up a balloon and tie it. Rub the balloon vigorously on your or your friend’s hair until you can see the hair standing on end…cool eh? Next place the balloon about 1cm above the pepper and salt mix…Watch the pepper jump and stick to the balloon!

For lots more experiments you can do at home including super bubbles, jumping sultanas, lava lamps and travelling water, check out our experiments page at: experiments/

Exploding rainbows – add some colour to your life with this fun, easy and safe experiment you are able to complete at home!

Science Experiments For KidsFor this experiment you will need:

  • 7 x small clear containers
  • Food colouring in the colour of the rainbow – red, orange, yellow, green, blue, indigo and violet (or as many as you have)
  • Baking powder
  • White vinegar
  • Teaspoon
  • Jug

Remember to ask for adult permission/supervision 

Science Experiments for Kids

  1. Prepare your clear containers – ideally do this outside or make sure to use a protective sheet as it can get a bit messy!
  2. Add baking powder to each of the containers using a spoon. A small spoonful should be enough but it will depend on the size of your container so maybe add two spoonfuls just in case!
  3. Add two drops of food colouring to each container – red food colouring to the first container, orange to the second, yellow to the third, green to the fourth, blue to the fifth, indigo to the sixth and violet to the seventh or the closest colours you have.
  4. Add vinegar to a jug then pour the vinegar into your containers.
  5. The reaction will happen quickly so make sure you are watching closely!

Enjoy your exploding rainbows.

The science: Baking soda and vinegar react together forming a chemical reaction. This chemical reaction produces carbon dioxide gas which causes the rainbows to explode! The carbon dioxide gas escapes causing it to overflow the container.

Colourful chemistry: make your own kitchen chemistry lab…with a cabbage!

Science Experiments For KidsMaking the colour-changing liquid (this is grown up job): Roughly chop half a red cabbage and boil in just enough water to cover it for around 10 minutes. The water should turn dark purple or blue. Keep the water and put the drained cabbage to one side. Leave it to cool.

Doing the experiment: You need some beakers (see-through ones are best). Put about 100ml of water in each one and add 2 tablespoons of the purple liquid. Now get experimenting! Try adding different things to see if you can make the liquid change colour. You could try: vinegar, lemon juice, milk, liquid hand soap, toothpaste, bicarbonate of soda, washing powder… anything else that you can find (check it’s safe!).

The liquid that you have made is called an indicator. Scientists use indicators to find out about chemicals. If it goes red or pink, the chemical is an acid, if it goes blue or green, it is an alkali. Did you find any acids in your experiment?

How to run a real science experiment at home?

Science Experiments For KidsDo your kids think science to be boring and puzzling? Well, a lot of kids have come up with the idea that science is not their thing. Textbooks with obscure words, strict teachers and complex formulas are why kids are not really into science.

Science Experiments For Kids

Please don’t despair! You can inspire your kids to learn. All you need is to show them that science can be cool. For example, you can run fun science experiments at home, like, an invisible ink message.

This is what you need:

  • 5 mL 1M cop­per(II) sul­fate so­lu­tion
  • 2 mL 10% am­mo­nia so­lu­tion
  • a cot­ton swab
  • a Petri dish
  • a plas­tic cup
  • a piece of white pa­per

Use a cot­ton swab to write a mes­sage on the piece of pa­per with the 1M cop­per(II) sul­fate so­lu­tion. No­tice that the mes­sage dis­ap­pears as it dries. To re­veal the mes­sage, put a few drops of 10% am­mo­nia so­lu­tion into the Petri dish and set the pa­per over the Petri dish. The mes­sage should ap­pear with­in 5 min­utes. Sounds fun!

Bubble inside a Bubble Experiment – Science Experiments for Kids

  1. Pour about 250 ml of warm water into the cup.
  2. Add 1 tablespoon of granulated sugar to the water. Stir the solution until all of the sugar is completely dissolved.
  3. Add 2 tablespoons of the washing up liquid to the water. Stir and try not to make a lot of foam.
  4. Make a bubble wand from a pipette. Use the scissors to cut off a tip from the bulb end of the pipette. You can also use a straw instead of pipette.
  5. Prepare a smooth very clean surface (kitchen table). Spread some of the mixture on it with your  finger. Make a big circle.
  6. Dip the cut end of your bubble wand into the soap solution. It must be coated completely.
  7. Blow into the dry end of your bubble wand and hold it close to the wet surface to create a large bubble hemisphere.
  8. Dip the bubble wand in the solution again and gently insert it inside the first bubble. Blow gently a second bubble on the wet surface inside the first bubble. You can make more than one bubble inside. Challenge yourself or your friends! Have fun!

Science Experiments For KidsTip: If you leave the bubble solution sit for 24 hours it will be much stronger.

About Little Volcanoes

Little Volcanoes provide original hands-on science classes, special events and birthday parties. They are for all little explorers and curious minds aged 2.5 – 9 years who are ready to do something different!

Janka is the founder and director and an enthusiastic experienced primary teacher who created her first ever science club 14 years ago when nothing like that was available for pre-school children at that time.

Our lessons are a unique combination of age appropriate science experiments with DRAMA, PRETEND AND SENSORY PLAY, which is so useful especially when your child is shy or has some sensory issues. Little Volcanoes have also created their ORIGINAL SONGS and rhymes to make learning memorable and long-lasting. Every week we learn a new interesting topic. Children will develop their vocabulary and their social, practical, analytical and fine motor skills while learning about the world around them.

Little scientists will be learning simple (or challenging) science concepts across BIOLOGY, CHEMISTRY, PHYSICS, EARTH SCIENCE, GEOLOGY, ECOLOGY, and ASTRONOMY. They will also learn some interesting facts from GEOGRAPHY AND HISTORY while having fun doing science experiments for kids!
