Exciting science experiments you can do outside

Science can be fun and exciting for children of all ages, and there are lots of simple experiments you can do with the things you have around the house and outside in the garden. Water-based experiments are particularly good fun to do outside.

Sink or float?

Take a look around your garden and let your little one find as many different items as they can. This could be leaves, rocks, flowers or sticks. Ask them about each of the items and whether they think they might sink or float in water. You could get them to organise them into two piles, depending on what they think they’ll do. Fill a bowl with water and place each item on the water and see what happens!

Walking water

This experiment is really easy to do and has a big wow factor for children. All you need is two empty glasses, paper towels, food colouring and water. Position your glasses about five centimetres away from each other, then fill one halfway up with water, add food colouring and stir. Take a strip of paper towel which is between three and five centimetres wide and place one end of it in the glass with water and the other in the empty glass. Leave the glasses for a while and when you come back you’ll see the water has ‘walked’ into the other glass.

Watermelon volcano

A great baking soda/vinegar reaction experiment that turns a watermelon into a volcano! Make a hole in the top of the watermelon and carve out the watermelon’s insides – like you would with a pumpkin (you can use the fruit you take out to make a yummy smoothie!). Try to make the hole as small as you can whilst still being able to carve. Next, put a good amount of baking soda, some washing up liquid, and a few drops of food colouring into the hole in your watermelon. Now, pour in some vinegar, step back and wait for your volcano to erupt!
