We’ve talked about respiration before when we made bread and used yeast to make the dough rise. Blowing up a balloon with yeast is another very easy experiment to demonstrate respiration in action and is quicker than making bread if you are short of time. What is respiration? Respiration is a chemical reaction which occurs…
Jelly is a great way to learn about changes of state as first it dissolves in hot water and then sets to become solid as it cools. Why does jelly set? Jelly sets because of a protein called collagen. Collagen is made up of three protein fibers wrapped around each other. Jelly contains gelatin, which…
Looking at food groups is such a fun thing to do. It gives children a real insight into the types of food they eat, and you can use it as an opportunity for taste testing. For younger children, you can introduce food groups in terms of what they are: There are five basic groups. Then…

Earth is located in an arm of the spiral. What is the Universe? When we talk about the universe, we mean everything that exists. Galaxies, planets…
Playing detective is one of my little ones’ favourite games, but to be a real detective, you need lots of science! So today, we’re going to make a magnifying glass. This activity is part of my playful science series, so don’t forget to check out the other simple science ideas too! How to Make a Magnifying…
Every time we go for a walk at the moment, my children look for dandelions with a full seed head to pick and then blow so they can watch all the tiny parachutes float away in the wind. We started talking about why they fly so well and their purpose. This is also a fun…
We are VERY excited to announce ( if you missed it ) that we are finalists in TWO categories for the MAD Blog awards. While we both hoped this would happen, we didn’t dare get our hopes up too much, so last week’s announcement has still not really sunk in. There are so many amazing…
‘Thank crunchie, it’s Friday’ seems the perfect phrase for today’s experiment as it involves learning how to make honeycomb with our easy honeycomb recipe. Once you’ve made the honeycomb and learned about the science behind the bubbles, the rest is up to you. Add melted chocolate, sprinkles, popping candy or anything else to make it…
Coin poppers are a brilliant experiment to demonstrate air pressure! What you need A small empty plastic drink bottle A 2p coin A small square of kitchen roll Method 1. Put the empty bottle in the freezer for about an hour to cool. 2. Cut a small square of tissue paper and put it on…
