15 Things To Make And Do With STEM-Obsessed Kids To Power Through Lockdown

We've got some brilliant free ideas for things to make and do that'll keep your STEM-loving kids entertained, educated and enthralled. Make fireworks in a jar, travel the world and even whip up something tasty in the kitchen. Most of these experiments and activities can be modified depending on the ages of your children, meaning you can go into more or less detail when you explain what you're doing and why. Whether your kids like building things, using technology or prefer the colourful arts and crafts side to STEM, there's something for everyone.

Inspiration straight to your inbox, every week

1. Create A Tornado In A Jar You'll need: jar with a lid, sand, water and washing up liquid Fill your jar 3/4 full and add one drop of washing up liquid. Add a sprinkle of sand to your jar - this will imitate real tornadoes, which get their murky colour from all of the dirt they pick up as they travel. Tightly screw the lid onto your jar. Turn it upside down and shake it for 1-2 minutes in a circular motion. Quickly turn it back the right way up and place it onto a table or counter and you'll see your tornado build, swirl and then fade away!

2. Magic Milk Experiment You'll need: food colouring, washing up liquid, cotton buds, full-fat milk and a shallow dish If you're trying to search for things to make and do with what you've already got at home, this activity is perfect. It might be a science experiment, but it also looks like a cool art project! Pour milk into your dish to about 1cm deep. Add drops of food colouring all over - the more colours, the better. Next, dip a cotton bud into washing up liquid and then touch the surface of the milk with it, holding it there for about 15 seconds. It'll turn into a beautiful rainbow in front of your eyes, all because of how the milk's fat molecules react to the soap!

3. Make A Volcano You'll need: plastic bottle, modelling clay, 2 tbsp bicarbonate of soda, 2 tbsp washing up liquid, 1 tbsp food colouring, a splash of vinegar and a plastic dish or container If you're hunting for ideas for scientific things to make, a DIY volcano never disappoints. Use your modelling clay to create a volcano shape around your plastic bottle before placing it into the plastic container. Add washing up liquid, food colouring and bicarbonate of soda to the bottle. To make the volcano erupt, add vinegar and watch the chemical reaction take place! If your kids are a bit older you can go into more detail and learn about how bases and acids react together and understand why the volcano reacts like this.
