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.
Do you know how salt melts snow? Grit is often sprayed on roads to stop cars from skidding on very cold days. What we call grit is a mixture of salt, gravel and stone. When snow falls on a road with grit applied, it mixes with the salt, lowering the snow’s freezing point and stopping…
Have you ever wanted to create your very own rock lab? These rock investigations include five easy tests to help children group and identify rocks based on their appearance and properties. It’s a brilliant first introduction to rocks for kids, with lots of fun rock activities for kids of all ages. There’s also a free downloadable…
The inside of the Earth consists of four main layers. The inner core, outer core, mantle and crust. The crust is the thinnest of the layers and is made up of moving pieces called plates made from solid rock. There are two types of crust: oceanic and continental crust. This activity is a great introduction…
2020 was definitely the year for bring very aware of how germs travel and spread between people. Luckily our bodies have lots of ways to protect us from potential pathogens. This activity is taken from my latest book Gross Science and illustrates the role snot plays in our immune system. Make a Snot Trap Snot…
If you’re immune to a particular virus or bacteria it means you already have the right antibodies in your blood ready to fight the pathogen when it enters your body. What is Natural Immunity? There are two ways a person can be naturally immune to a pathogen. When antibodies are passed from a mother to…
The Earth is known as a Goldilocks Planet, as, rather like the littlest bear’s porridge, it is neither too hot nor too cold. It is this favourable temperature which allows life to exist. Earth is the only planet we know of where water can be in the form of a gas, liquid or solid ( remember…
I originally created these science experiments for parents at home with children during lockdown 2020, but they work well as science activities for home or school at any time of year. The idea behind Tray a Day is that everything you need for the activity fits in a tray, so it’s easy to set up…
We made these virus models to show how different viruses have very different structures. They are also different sizes ( our models are not to scale ) and infect different types of hosts. At a very basic level each virus consists of genetic information in the form of either DNA or RNA surrounded by a…
A virus is a very tiny organism that can only live and reproduce inside another living cell. The cell the virus invades is called the host cell. The virus basically turns the cell into a factory to make more viruses which then invade more cells. Viruses consist of a stand of genetic information ( DNA…
If you’re searching for child-friendly science experiments, look no further! Most of the science experiments on Science Sparks are perfect for science at home. I try to use materials that are either easy to find or that you probably already have around the house. All my science investigations and activities are simple, easy to explain,…
