These summer STEM Challenges are great fun, no matter the weather, and they all use materials you’ve probably already got around the house.
Make treasure maps, play dough models, fizzy potions, sugar cube towers and find rainbows in bubbles.
Gather together friends or family and start experimenting. We’ve got enough ideas to keep you busy all summer long.
We teamed up with the lovely Mrs Mactivity to create the 16 printable STEM challenge cards, which can be downloaded below.
Summer STEM Challenges
Sugar Cube Structures
Make sugar cube towers and place different materials, such as kitchen foil, cling film etc in between the cubes to investigate which material is the most waterproof.
This is a great activity to turn into a game of who can build the tallest tower before it collapses!
Treasure Maps
Use cold coffee or tea to make white paper look old, then draw a map of your garden, house or even a map from a story!
Secret Messages
Write secret messages with lemon or lime juice!
Fizzy Potions – Summer STEM Challenge
There’s nothing better than a fizzy potion outdoors on a sunny day. Add baking soda, vinegar and dish soap for a super eruption!
To make this extra exciting, add a little red cabbage indicator to make colour changing potions!
Ice Painting
Freeze a sheet of ice and paint over the top. Once you’ve finished, wipe the ice clean and start again!
Flower Dissection
The best way to learn about the different parts of a flower is to take one apart! Can you spot all the different parts?
Once the stem, petals, leaves and roots have been identified try to spot the male and female parts of the flower.
Jump Up!
Make jumping frogs, jumping unicorns and anything else you fancy with this easy static electricity experiment.
Build a Raft – Summer STEM Challenge
Make a raft from whatever materials you have around the house and test how much weight they can hold.
Play Dough Models
Make a play dough model brain, bone, heart or anything else you fancy!
Bubble Wands
Build your own bubble wands with pipe cleaners and straws! This is also a fun activity to learn about how rainbows form.
Bean in a Jar – Summer STEM Challenge
Did you know you can grow a bean in a jar? Or use paper or card to construct a beanstalk for Jack!
