The most important thing to remember is that science should be fun! Do let us know on social media what you think of our cool science experiments for kids and if you can think of any more ideas we can add to our list.
Simple Science Experiments for Kids
Most of the science experiments on Science Sparks are simple anyway, but to make it even easier, I’ve written a roundup post of some of the easiest experiments for kids.
All these activities use materials you probably already have at home and are great for learning about the scientific method.
I’ve also got a list of science experiments every child should do at least once with a FREE printable experiment checklist so budding scientists can tick the experiments off as they go along.
Chemistry Experiments for Kids
Baking soda and vinegar tend to be the staple ingredients for chemistry experiments at home, but there are lots of other chemistry concepts that can be explored easily and safely outside a lab too.
Mento in Coke Experiment
Find out what happens when you drop a mento into a just opened bottle of coke ( you’ve got to be quick before the fizz fades ).
Exploding sandwich bag
Mombrite has a fantastic exploding sandwich bag investigation. This is a great activity for learning about chemical reactions.
Blow up a balloon with lemon juice
Blow up a balloon with lemon juice and baking soda. Vinegar also works instead of lemon juice and trying a mixture of yeast, sugar, and warm water is a fun extension activity.
Film canister rocket
If you’ve got some old film canisters, a film canister rocket is a brilliant outdoor chemistry activity. These fly up with a bang, so take care when launching and stand back.
More chemistry experiment ideas
Try some fantastic density experiments and tricks, make your own pH indicator with red cabbage and look through my full collection of chemistry experiments for kids.

Biology Experiments for Kids
Plant cell model
One brilliant way to learn about cell structure is to make a plant cell model. Modroc cell models are great as they last a long time.
Respiration activity
Learn about respiration and yeast by making a pizza. The pizza can then also be turned into a plant cell model! The carbon dioxide produced as a by-product of respiration causes the pizza dough to rise.
Surface area to volume ratio
Surface area to volume ratio is an important concept in Biology. One fun way to learn about this is by using sugar cubes.
Learn about life cycles
My edible butterfly lifecycle model is a fun ( and delicious ) way to learn about lifecycles.
Don’t forget to check out the rest of my collection of biology science experiments.

What is Science Sparks?
Science Sparks contains 100s of free science experiments and activities for kids of all ages. Most of our experiments only require very simple materials and ingredients that you likely already have around the house. What are you waiting for? Choose an activity, create a cool science project, try a STEM challenge and then show your friends and family what you’ve learned. We’ve also got a few science tricks that are sure to impress an audience!
Still not sure where to start? Try our list of everything you need for science at home and start with something simple. Try making a bubbly lava lamp or a craft or lolly stick stick catapult and go from there. Thinking of a science question and then working through it to find an answer is another great approach. We’ve got some great science questions for kids to get you started.
For children who aren’t especially interested in science, give one of our book themed science experiments a go. These are also great for younger children, as adding context to an activity really helps keep kids engaged.
Don’t forget we’ve also got lots of holiday themed science activities as well as an extensive list of easy STEM challenges and exciting science project ideas.
BENEFITS OF SCIENCE FOR KIDS
Whatever the age of the child, the benefits of science experiments and activities are huge. The best thing about science is that you probably already have everything you need for awesome science experiments in the kitchen or around the house.
- Encourage curiosity. Children can use science experiments and activities to find answers to questions which will probably lead to more questions and hopefully help nurture a natural curiosity and understanding about the world around them.
- Get outdoors – science is a great way to encourage children to go outside. Whether it’s making rockets, building water walls or just trying some sinking and floating, it’s always good to be outside.
- Planning skills – science projects help develop planning and problem-solving skills and the resilience to keep trying if something doesn’t work the first time.
- Teamwork – science experiments are a brilliant way to encourage children to work as part of a team and for parents to spend quality time with children too!
