Find the volume of an irregular object

This clever and simple method for finding the volume of an irregularly shaped object is thought to have been discovered by a scientist named Archimedes, who noticed the water level of his bath rising as he lowered himself in. Archimedes realised he could find the volume of any object by measuring the amount of water […]

Make your own anemometer

Anemometers are used to measure wind speed. The cups catch gusts of air which makes them spin around. Measurements are taken by counting the number of revolutions the anemometer makes in a set period of time. The stronger the wind, the more revolutions the anemometer makes. Modern anemometers tend to be digital, but the principle […]

Love Bug Drawing Robot

This cute love bug is a great Valentine’s Day STEM Challenge or fun science craft for any time of year. The cork on the motor spins around making the cup vibrate and move around. As it moves, the felt tip pens make a mark on the surface below. Art-bots can also be made with a […]

Valentine’s Day Science Activities for Kids

I have to admit we don’t really do Valentine’s Day in our house, but I do love theming science experiments to a special occasion so here are some easy Valentine’s Day science experiments. Make a skittles heart, a paper aeroplane delivery system, colour-changing love potions and lots more! Valentine’s Day Science Experiments Heart Patterns First […]

Science Experiments you can do in a Jar

Here at Science Sparks, we try to make science as easy and accessible as possible. When I ask people why they don’t do more science at home with children, one of the answers is usually that science experiments are messy. While this can most definitely be true, there are also lots of non-messy science investigations […]

How to lift an ice cube with a string

This science experiment using ice and salt is a fantastic demonstration of why salt is used to de-ice roads. It’s also a fun science magic trick! When salt is spread on the road in winter, it dissolves in water on the surface and lowers the freezing point of the water. This means the outside temperature […]

Weather Science Experiments for Kids

Today’s round-up is full of great weather science experiments and investigation ideas. Learn about extreme weather with a tornado in a jar, record rainfall over a period of time, create a water cycle in a bag and lots more easy ideas for learning about the weather. Observing the weather is a great way to practice […]

Around the World in 50 Experiments – Canada

Today, we’re off to Canada on our trip Around the World in 50 Experiments. Don’t forget to print the passport to record everywhere you go! Canada is the second largest country in the world after Russia, with the USA a close third. Canada is vast, rugged and beautiful, home to mountains, forests, vast wetlands, open […]

How To Defy Gravity – Magnet Trick

This fantastic and easy demonstration of gravity and magnetism will impress kids of all ages. The paperclip doesn’t fall because it is attracted to the magnet and doesn’t jump up to the magnet as it is held in place by string, making it look like it is defying gravity and floating in the air!! If […]

Easy Toy Car Science Experiments

Toy cars are a great tool for learning about forces such as friction, momentum, inertia and the effect of changing gradients of ramps. You’ll need a few extra items for some activities, but hopefully, you already have most of them around the house. Science investigations using toy cars Toy car friction ramp Our DIY friction […]
