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 the wind on a battleship at sea. When is a hurricane warning issued? Hurricane warnings are issued when winds reach…
Wind turbines use energy from wind to generate electricity. Each turbine has a generator inside. When the blades rotate they turn the generator which produces electricity. This is a form of non renewable energy, it doesn’t get used up and doesn’t produce harmful polluting gases. You’ll need A square of paper – about 15cm x…
At Science Sparks, we love autumn with its crunchy leaves, beautiful colours, and crisp, fresh air! I’ve compiled a huge collection of autumn science experiments that you might like, and I’ve also pulled together these autumn STEM challenges to help you make the most of the changing seasons. If you’re looking for more general science experiments, try my collection…
We’ve got quite a collection of activity ideas for learning about materials and their properties so I’ve brought them all together in one very long post. If you have any more ideas, I’d love to hear them, so do leave a comment below. You could also share photos to the Science Sparks facebook page. Don’t forget…
A wind vane ( sometimes known as a weather vane ) is used to show the direction of the wind. Wind vanes are mounted so they can spin under the influence of the wind. This very simple wind vane is made by attaching a straw to the eraser end of a pencil with a pin…
This Three Little Pigs STEM Challenge is a brilliant science experiment for learning about the stability of structures and properties of materials. It’s great for early years science age, but it can also be extended for older children. If you like this, you might also like my Gingerbread Man science experiments. We made six different types…
This mini motorised boat was a great STEM challenge that kept us busy for hours!! We kept adding extra bits to make it work better and were really happy with the end result. If you like this you’ll love my other easy STEM challenges or if you’re looking for something a bit easier to put…
Some of the easiest science experiments are the most fun and you don’t always need lots of equipment either, there are a lot of investigations you can try that don’t need much more than just you! If these aren’t quite what you’re looking for you might also like my science experiments using paper or my…
These super simple cardboard STEM Challenges are a great project for a rainy day. Make a DIY slingshot, cardboard circuits, marble runs or even cardboard sculptures! Raid the recycle bin to see what you can find and go from there. You might also like my experiment instruction sheets and science fair project ideas! Super Simple…
This homemade articulated grabber is a brilliant STEM Challenge or STEM project, that works brilliantly and is easy to construct as well! We cut up a shoe box to make ours as the cardboard does need to be quite sturdy, but you can use whatever you have handy. If you like this activity you might…
