Several years ago, we started creating Easter egg hunts with codes as clues to make searching for the eggs take a bit longer. The codes started out very simple ( letters replaced with numbers ) but have become increasingly complex over the years. I’ve created some free printable easter egg codes to make this year’s…
Magic opening flowers are a brilliant, super simple science investigation using just paper and water. The folded paper flowers open up as the paper absorbs the water. They are a great way to learn about capillary action and transport of water in plants too. You can make these as simple or creative as you like….
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…
What do you think your body would be like without bones? It’d be all wobbly like jelly. The skeleton acts like scaffolding holding up our soft tissues. It’s a bit like an internal suit of armour. This collection of skeleton activities is great for learning about the structure and function of the skeleton and how…
Olympic and sports day fever is about to start, so I’ve put together a collection of fun sport-themed science experiments and investigations. You can find out what happens to your heart rate and breathing as you exercise, make a model of a heart and lung, discover why balls bounce, test reaction time and lots more…
Do you know how to make a solar oven? I’ve always wanted to try one, so when the UK was unusually hot last summer we gave it a go. It was actually much easier than I expected and our marshmallows melted very quickly. If you fancy setting up a few garden activities on a sunny…
This viscosity experiment is a fun way to discover how different liquids flow. Or just to have a race with ketchup and other kitchen ingredients! The rate at which different fluids flow can vary considerably, this is called resistance to flowing viscosity. We did this on a big board in the garden, but it works…
This collection of science experiments for learning about the human body is perfect for encouraging kids to learn about their bodies! I’ve split the ideas into three age groups: preschool, primary age ( 5-11 ) and secondary ( 12+) but these are very loose recommendations. Hopefully you’ll find something that sounds fun to try! I’ve…
We’ve dissected flowers many times before, but this was our first attempt at a 3D flower model. A model is a great hands-on way to learn about the structure and function of plant organs and the importance of pollination. I’ve also made some FREE flower structure revision cards you might like. 3D Flowering Plant Model…
This fun tooth decay experiment with egg shells is all about teeth and how to keep them healthy. First, we discussed the importance of brushing teeth every day, and then we chatted about foods that are good for your teeth and those that aren’t. Sugary, sticky foods are not good for teeth as they stick…
