Enzymes are biological catalysts. In simple terms, they speed up chemical reactions. Living organisms have chemical reactions happening in them all the time. One way enzymes are used is to break down large molecules. For example, enzymes called carbohydrases convert carbohydrates into simple sugars. This type of reaction needs to be carefully controlled. Reactions outside…
Lots of people have been asking me for school science club ideas recently, so I’ve put together a collection of science experiments and activities that I think would work really well for Primary/Elementary school age children at a science club! If you’re a teacher, parent or home educator looking for easy, inexpensive, inspiring and exciting school…
Have you ever wanted to create your very own animation? One way to do this is with a simple flipbook. An animation flip book is a series of pictures arranged in a flip book that change slightly from one page to the next. When you flip through the book, the images appear to move, creating…
My science experiment fortune teller is an easy way to make science fun at home. Fold the fortune teller, play with a friend and then start experimenting. The activities are designed to be easy to carry out using only inexpensive materials. Each can also be extended if needed, so it’s not just a quick five…
Red cabbage indicator is often used as an introduction to pH and indicators, but did you know you can make an indicator from blackberries? Blackberries contain anthocyanins, which are pigments that change colour depending on pH. Anthocyanins are a natural indicator. An indicator is a substance that changes colour when added to solutions of a…
Our fun Pokemon catapult is a great way for children to learn about the effect of angle and force on how a projectile flies through the air. They are super easy and quick to make with lots of opportunities for further investigation. Once you’ve made the catapults, scroll down for more easy Pokemon STEM Challenge ideas. How…
Slows are famous for being SLOW. They move slowly and sleep a LOT! This general lethargy is reflected in their digestive habits. It takes you just a few hours to digest a meal, but it can take sloths up to a month, and they only poo once a week! Sloths spend most of their lives…
Our Summer holidays are about to start, so I thought it would be a good time to spruce up this post full of Summer Science Challenges for kids. All the activities are very simple and use mostly things you probably already have around the house. For an ultimate summer of science, try one activity each…
A tower of slippery ice cubes might sound impossible to build, but adding a little salt makes it much easier! Materials Ice – 4-8 cubes Salt Plate or tray Instructions Try to stack the ice cubes. They will topple off each other. Leave the ice cubes to melt for a few minutes. Try to stack…
Beat the heat or embrace the cold with my collection of cool ice cube experiments. From exciting colour changes to gravity defying tricks and icy engineering challenges, get ready for some surprisingly simple, hands-on science that’s sure to make your summer cooler. You only need ice and salt for most of these investigations, making them…
