Imagine you have a blank map of the world. How many colours do you think you’d need to colour it so that no two countries sharing a border are the same colour? The answer is surprisingly low, just ...

Get ready to unleash your inner scientist with my HUGE collection of science experiments and investigations for home and school. Most activities use inexpensive materials you probably already have ...

Cut the top off the bottle and place it upside down inside the main body. Get an adult to help, as the edges might be sharp. Place a ruler on the side of the bottle and mark in cm up the side. Bury ...

The Beaufort Scale was named after Sir Francis Beaufort ( a hydrographer with the Royal Navy ) and lists the effects of increasing wind speeds. The scale was initially designed to show the effects of ...

Now you know the science behind the reaction, why not try one of our many explosive baking soda and vinegar experiments? One of our favourites is fizzy colour changing potions! These use red cabbage ...

After being inspired by a family STEM challenge evening at school, we’re a bit obsessed with marble runs! I love that you can make them from recycled materials so there’s no cost, they are great to ...

Digestion is the process by which large, insoluble molecules of food are broken down into smaller, soluble molecules that the body can use. Digestion starts in the mouth, where food is broken into ...

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, ...

Visible or white light is made up of a range of colours each with a different wavelength. One way to see the different colours is to use a prism to split the light. When white light enters the prism ...
