The Universe is gigantic, bigger than you can probably imagine. If you were to stand in the middle of the Universe, the outer edge (if there is one) would be a huge 440,000,000,000,000,000,000,000 km away, and that’s just the observable Universe. We don’t really know how big it actually is or if it’s infinite. Did…
Cells are the fundamental units of life where most of the essential chemistry and functions that keep us alive happen. Cells are the building blocks of every organism and make up most of the structures within the body. Facts about cells What’s the difference between a prokaryotic and a eukaryotic cell? Prokaryotic cells are simpler…

Magnets are always fun when used in science experiments and demonstrations. They are fairly inexpensive to buy and can be used in lots of creative ways. We still play with our magnet cars years after making them! This simple dancing magnet activity uses a basic frame to hold a magnet in place while other magnets…
One of my aims with Science Sparks is to make science as accessible as possible to kids and parents of all ages. I try to keep all the experiments as simple as I can, but the list of materials can often mount up and be a little overwhelming. With that in mind, I’ve compiled a…
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…
