Easter is just around the corner, so I’ve put together a collection of egg experiments perfect for this time of year. Eggs are great for experiments as they are inexpensive, easily available and very versatile. We try not to waste food at Science Sparks, but for most of these ideas, you can still eat the actual egg. However,…
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…
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…
An easy way to make salt crystals is to dissolve table salt in water and leave the solution somewhere warm until the water evaporates, leaving behind sparkly salt crystals. We also made coloured salt by adding a little food colouring. This activity and more salt science experiments can be found in a salt science activity…
Lemons are a small, yellow citrus fruit that taste sour, smell good and can be used for lots of very simple science experiments as they are acidic. I’ve collected 5 of my favourite science experiments using lemons for you to try at home. All are very easy and don’t use many resources other than the…
If you’re thinking of trying a science activity at home for the first time, or are a more seasoned kitchen scientist, red cabbage indicator is perfect! The humble red cabbage is great for making colour changing potions, testing the pH of different things around the kitchen and generally a great introduction to science at home,…
Next time you boil up some red cabbage, make sure you save the liquid as it can be used for lots of easy science experiments. This red cabbage breath test is a fun twist on the more traditional testing the pH of different substances, although why not do both? Did you know you can even…
From the outside a raw egg and a hard boiled egg look the same, so how can you tell the difference? How can you tell if an egg is raw or hard boiled? The key is in the spin! A hard boiled egg will spin nicely and a raw egg will wobble. The raw egg…
