This science experiment using ice and salt is a fantastic demonstration of why salt is used to de-ice roads. It’s also a fun science magic trick! When salt is spread on the road in winter, it dissolves in water on the surface and lowers the freezing point of the water. This means the outside temperature…
This easy magic milk science investigation is fantastic fun for kids of all ages. All you need is whole milk, food colouring and a little dish soap to create crazy colour explosions. Older children can use this activity to learn about emulsions. The reaction that gives the colourful display is between the fat molecules in the…
Do you know how to make a lava lamp? DIY lava lamps are one of our favourite science experiments as they are super simple to make, can be used over and over again, and you can be as creative as you like with them. We’ve made Minions, reindeer and even snowmen lava lamps! Lava lamps…
Do you know you can make a pH indicator with the red leaves from a poinsettia plant? Red poinsettia leaves contain anthocyanins which change colour in the presence of acids or alkalis. Acids have a low pH ( below 7 ), and alkalis have a high pH ( over 7 ). If it’s not the…
This dissolving candy canes activity is a great science activity for before Christmas when the festivities are in full swing or after Christmas to use up any leftover candy canes. The idea is to place candy canes in different liquids to find where they melt the fastest. We used hot and cold water and vinegar,…
If you eat or drink too quickly, you might find you burp! Burping is how extra gas is expelled from the body. The gas is forced out of the stomach up the oesophagus and out of the mouth! These burping balloons are very easy to set up and great fun to watch. The balloons will…
This lovely, colourful science experiment is super easy to set up and carry out, but looks amazing! As well as being fun to watch, it’s also great for learning about density ( the oil layer floats on top of the water ) and diffusion ( as the food colouring spreads out through the water layer)….
This simple salt lava lamp is a fun twist on the more traditional homemade lava lamp that uses a fizzy tablet. The salt lava lamp doesn’t look quite a good, and isn’t as reusable but is still a nice science activity for learning about density. You’ll need A glass jar or glass Vegetable oil –…
Today’s post is part of my United States of Science series. The idea is you print a map of the USA and colour each state as you learn about it with a fun science activity. In this activity, you find out why the Statue of Liberty is green! New York New York City in the…
This easy science activity demonstrates the difference in density between hot and cold water. It can be a bit messy so I would either do it outside or put the jars in a tray. The demonstration works as cold water is more dense than hot water so the hot water sits on top of the…
