What is a Mixture? A mixture is a substance in which two or more substances are mixed but not chemically joined together, meaning that a chemical reaction has not taken place. Mixtures can be easily separated and the substances in the mixture keep their original properties. Imagine mixing skittles and full size marshmallows, the individual…
We’ve looked at how objects absorb water before using sponges, underpants and even the good old walking water experiment. Today, we’re conducting an absorbing experiment with a twist, aiming to halt the process and investigate which materials absorb water and which don’t. Sugar cubes work well as they absorb water quickly, and if you add…
Forces are all around us and affect everything we do. With that in mind, I’ve put together a collection of ideas for learning about forces and motion with fun forces and motion experiments for everyone, from preschoolers to grown-ups. There are friction experiments, gravity experiments, air resistance experiments, and lots more! Each activity is easy…
When making some jelly last week, I noticed the packet said it wouldn’t set if pineapple, kiwi or papaya were added to it. We decided to find out why pineapple stops jelly setting. If you love science in the kitchen don’t forget we’ve also got 50 fun kitchen science experiments and ideas for a science…
We have a little magnet kit that we play with frequently. It’s great fun, and the children are always so surprised that they can actually feel the force pushing the magnets apart. To explain magnetism further, we made a magnet maze. First, we played to see which type of objects a big magnet stuck to….
Before we had clocks and watches, people used sundials to mark the passing of time. A sundial measures time by the sun’s position and usually has markings for each hour of sunlight. Sundials have something in the centre that casts a shadow over the markings showing the time. There are lots of ways to make…
These Key Stage 2 science experiments are great for school or home and perfect to sit alongside science in the classroom for Key Stage 2 in the UK or for children aged between around 7-11 who love science! If a science challenge is more your thing, we’ve got easy STEM challenges using newspaper, FREE STEM Challenge cards and lots…
Green plants make sugar for growth by a process called photosynthesis. Photosynthesis is a process where light energy is converted to chemical energy in the form of sugars. Photosynthesis provides the main source of oxygen in the atmosphere and is essential for almost all life on Earth. Photosynthesis made simple Plants use sunlight, water, and…
I was so surprised at how well these easy paper spinners ( or paper helicopters ) worked. They take less than two minutes to put together, spin amazingly well and inspire some great investigations. They are also part of my Tray a Day series, which is a program of science activities using simple materials that…
I can’t take the credit for this one as my 9 year old made it in school last year, but it’s just too good not to have on Science Sparks. I love that it’s more than just a circuit. One of my daughters made a long torch and the other a head torch. Both are…
