One way to illustrate density is to pour liquids with different densities on top of each other. The liquids that are the most dense sink to the bottom. I tried to make a summer ice cream version, but the sprinkles dissolved in the water, making it a bit murky looking. Why does this work? Each…
This activity is great as a follow-on from our hand washing exercise and a brilliant visual way to introduce the concept of microorganisms. The idea is to observe what grows on potatoes over a period of time. We boiled the potatoes in water for 10 minutes first to destroy any microorganisms already present on the…
What we were hoping to show with this cool splatter pattern investigation was that a water balloon dropped from a greater height falls with more speed and has a bigger splatter pattern than a water balloon of the same size dropped from a lower height. As with many science investigations, we hit a few issues…
Welcome to Day 4 of our Spectacular Summer Science series. Today, we’ve been on a minibeast hunt. The girls are fascinated by all bugs and insects and are not the least bit squeamish. We downloaded some fun observation forms from Twinkl to make it more exciting and to encourage writing. S was thrilled to be…
The heart is a muscle that functions as a very powerful pump to transport blood around the body. It beats between 60 and 100 times a minute but can beat even faster than that if needed. The blood transports nutrients and oxygen to cells in the body, and waste products are removed. The right side…
On a rainy day, my children can often be found skidding down our hallway. We have wooden floors, so they are slippy enough to be fun, but not so slippy it’s dangerous. We have found that skidding is a lot more fun when wearing socks, but why is this? The answer is Friction. Friction is…
Today is the first day of the summer holidays for us, and I have a big plan to post a science activity every day for the whole six weeks. We’re kicking off with a favourite reaction, baking soda and vinegar. The reaction between baking soda and vinegar is a great first chemical reaction for children…
Where possible I always get my children to wash their hands before eating. The bigger two have made up a song to encourage little H to wash hers properly, it goes something like this: Rub and scratch, rub and scratch Or you’ll get worms and germs worms and germs. la la la la Lovely, don’t…
How do you make a lolly stick race across water? Would you believe me if I told you all you needed was a drop of washing-up liquid ( dish soap ) and some water to do a fun surface tension experiment? Racing lolly sticks – surface tension experiment You’ll need Water A large container –…
My 6-year-old loves to build, whether it be LEGO, wooden blocks or junk modelling, he is always constructing something, so I knew he would enjoy the Magnetic Polydron set, but what has surprised me is how much my younger girls have enjoyed them. The first thing H did was order them by colour, which would be…
