Science Sparks is full of easy and fun science experiments for kids to do at home. Our fun science investigations include engineering, coding, biology, chemistry and physics experiments.
Learn more about the wonderful world of science by trying our exciting science experiments, cool facts, free printables, photos and videos. We’ve also got a great collection of STEM projects, STEM Challenges and science fair projects.
Our science experiments include removing the shell from an egg, launching bottle rockets, create edible life cycles, making lava lamps and lots more science experiments for kids of all ages.
This week we are investigating why balls bounce and how different balls bounce differently on different surfaces. Balls bouncing seems like a simple concept, but the science behind it is quite complicated, so please bear in mind that we have simplified it for our audience. I asked the children to choose three balls of different…
It is always tricky to get children to understand that living things can get eaten by other living things. We have tried very hard to make sure my children know that a chicken in a packet was once a live chicken and that they are food for us. So with that in mind, we decided…
We love a science experiment that seems like a magic trick, and this activity is one of the best. We’re going to find out how to make hot ice. Imagine saying to people, ‘I can make hot ice!’ They wouldn’t believe you would they? As far as science theory goes, they shouldn’t, we know that…
Here at Science Sparks, we love experiments using eggs. Eggs are generally inexpensive and can usually be eaten before or after the activity, so there’s no waste. These are my five favourite Egg Experiments. Five Eggy Experiments Make an eggshell disappear Make an eggshell disappear! This is like magic! Watch the shell of an…
When I brought out the spaghetti and marshmallows, I think my children thought we were having some kind of weird and wonderful dinner, not building structures. This is a great STEM activity for children of most ages, as you can tailor it to their understanding. I let my 2-year-old build whatever she wanted, and she…
Today we are looking at the difference between things being wet and dry. This investigation is so simple I did it with my 18 month old,  who loved dipping her fingers in the different pots and saying ‘wet’, so it is a great preschool science activity but can also be extended for older children. What you…
Why does food rot? Have you ever noticed that if you leave an apple (or any fruit ) for too long, it starts to rot or decay? This can lead to significant food waste, so it’s important to understand how to store food items to keep them as fresh as possible. Why does food rot?…
I am a huge fan of HABA toys, so I was very excited to receive this Terra Kids Windmill construction set from their Terra Kids range to review. Terra kids products are a great introduction to science and nature and include not only construction kits but also equipment such as telescopes and microscopes for exploring…
This is a brilliant investigation for finding out how waterproof different materials are. I printed a picture of a chicken and asked the children to colour it in, then gave them a selection of materials to protect the chicken from water. What you need Instructions Place the squares of material over the picture. Sprinkle water…
The transformation from Caterpillar to butterfly is one that hooks in children, however old they are. We are big fans of the Hungry Caterpillar by Eric Carle in this house, and it is a great way to introduce the lifecycle of a caterpillar. Firstly we read the story. Then we talked about a cocoon and…
