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…
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…
Freezing point depression occurs when a substance lowers the freezing point of another substance. One example is adding salt to water. A solution of salt and water has a lower freezing point than water alone. Melting and freezing: a recap Melting is when a solid turns into a liquid. The temperature at which a solid…
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…
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…
A magnet is an object that produces an invisible magnetic field. A magnetic field is an area where magnetic materials experience a force. Objects attracted to a magnet are either a magnet themselves or are made from a magnetic material. The magnetic force in a magnet flows from the north to the south pole, which…
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…
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…
Toy cars are a great tool for learning about forces such as friction, momentum, inertia, and the effect of changing ramp gradients. For some activities, you’ll need a few extra items, but hopefully, you already have most of them around the house. Grab some toy cars and start experimenting! Science investigations using toy cars 1….
A steady hand game is a brilliant mini electricity or design project and great for working on hand-eye coordination too! I made a reindeer themed game just before Christmas, but you can twist the copper wire into any shape you want. If this isn’t quite what you’re looking for I have lots more simple electricity…
