If we want to grow a plant, we usually do this by planting a seed. The seed is produced by sexual reproduction (two parents), meaning that the egg from one plant and the pollen from another have met and formed a seed, resulting in the plant having qualities from both its parent plants. However, what…
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…
Bubbles are one of the most fun things to play with…but what colour are they? Transparent? Clear? See-through? Did you know you can see all the colours of the rainbow in bubbles? How to make rainbow bubbles An empty clear bottle Washing up liquid Water A sink An overcast day (works best)I Fill the bottle…
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…
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…
This germination science investigation is very simple but fascinating. Did you know you can grow a bean in a jar with just a little water? Once the seed has germinated, you can place it in soil for the plant to finish growing. The jar allows children to see the seeds, roots and shoots easily. What…
