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.
I’m a bit last minute posting these firework crafts as tomorrow is Bonfire Night in the UK, but they came out so well I didn’t want to wait for New Year. All you need is paper, paint and an old salad spinner to make these easy Firework Spin Art pictures. Firework Crafts – Spin Art…
Last December, I decided to build a giant LEGO® Santa at the last minute. We’ve got a LOT of LEGO®, so I thought it’d be a great way to clear some bricks out of storage and have a great Christmas decoration. I massively underestimated the number of bricks needed and ended up buying a lot…
Animal and plant cells have three main differences. They both have a nucleus, cytoplasm and cell membrane, but only plant cells have a cell wall, vacuole and chloroplasts. We used jelly to create an easy plant cell model showing the main features of a plant cell. See our animal cell model post for more about…
Biology is the study of life and living things, including plants, animals and microorganisms. Biologists refer to living things as organisms. This collection of biology experiments for kids covers some of the most important concepts in biology There are many different branches of biology, including: Ecology – the relationships between organisms Zoology – the study…
Sterling silver jewellery tarnishes easily because it contains copper. Copper makes silver stronger, but it binds with particles of sulphur in the air, producing silver sulfide, which is the black layer you find on silver jewellery after a period of time. This easy activity cleans jewellery by using a chemical reaction between aluminium foil, baking…
We’re celebrating the beginning of autumn with some lovely apple experiments today! Turn apples into boats, experiment with different ways to preserve them, find out why food goes bad and make your own delicious apple cider. If you’re not a big fan of apples but still love autumn, try my autumn and fall STEM challenges instead! Easy…
Colourful science experiments are often much more engaging for younger children than less visually engaging activities. Adding colour to a lava lamp, volcano, or density demonstration makes the activity feel extra special. I’ve pulled together a list of my 10 favourite colourful science experiments for kids of all ages. 10 Colourful Science Experiments for kids…
Birds can fly because they have wings, a streamlined body, strong muscles and very light, hollow bones. Birds’ bones are very strong and perfectly adapted for flight. They have a dense, strong exterior and an interior strengthened with criss-crossing ridges and webbing. The hollow interior isn’t just to reduce the weight of the bone. Bird…
A convection current is the movement of a fluid ( such as air or water ) caused by differences in temperature. When part of a liquid or gas is heated, it expands and becomes less dense. The warmer, less dense fluid rises upwards, and the cooler fluid falls to take its place. This cycle of…
It sounds completely counterintuitive, but whether hot water freezes faster than cold water has been debated for centuries. The Mpemba Effect The Mpemba effect is the term used for hot water freezing faster than cold water after a Tanzanian student named Erasto Mpemba found that his mixture of hot milk and sugar froze faster than…
