Written by Our Summer holidays are about to start, so I thought it would be a good time to spruce up this post full of Summer Science Challenges for kids. All the activities are very simple and use mostly things you probably already have around the house.
For an ultimate summer of science, try one activity each day, or just pick and choose the ones you like when you have a bit of spare time!
Why do a science challenge?
Science challenges are great as they give children the opportunity to work with more freedom than a traditional science experiment. Open-ended challenges can be great for teamwork and independent creative thinking. They’re also great for a parent/child project too!
FREE Printable Science Challenges
The lovely Mrs Mactivity has also created us some fun printable science challenges that you can cut out and use as prompts. Scroll to the bottom of the post to download.
If you haven’t heard of Mrs Mactivity, do go and take a look at her website, she has some wonderful primary resources available.
Science Challenges for Summer
Build a tower with sugar cubes
How tall can you build a tower before it falls down?
What happens if you spray the cubes with water?
Can you add anything to waterproof them?
Make your own lava lamp
All you need to make a lava lamp is oil, water and an Alka Seltzer or effervescent vitamin tablet. These are great as they can be used over and over again. Just wait for the reaction to stop, add a bit more Alka Seltzer, and it’ll start all over again!
Make a treasure map
Use coffee or tea to colour your paper and draw a treasure map. Can your friends follow the trail?
This is great for experimenting with different concentrations of liquids too. A more concentrated tea or coffee solution will give a darker coloured map.
Invisible ink
Just mix a little lemon or lime juice with some water and draw your message on some paper.
Ask an adult to put it in the oven, and your message will appear.
What can you build with a cardboard box?
Can you build something functional with a cardboard box?
We added a kitchen roll holder and space for a sink to our cardboard kitchen.
Make a solar oven
Can you make S’mores in a solar oven?
Simple sinking and floating
Can you design a sinking and floating experiment? Make predictions first, then investigate to see if you’re correct. Do any of your items surprise you?
Spinning felt tip pens
Use cardboard discs to make spinning pens. You could try with paper and thinner/thicker card to see which works the best.
Coke and Mento Reaction
Drop a mento into a bottle of fizzy drink and watch what happens. Remember to stand back and drop the mento in as fast as you can!
Do low sugar drinks work better than full sugar varieties?
The coke and mento reaction is a science activity everyone should try at least once 🙂
Go on a bug hunt
What bugs can you find around your garden?
Investigate which substances react with baking soda
Can you predict which substances will react with baking soda? Were your predictions correct?
Set up an easy egg drop experiment
Something like our Humpty Dumpty egg drop experiment always works well
Which material protects the egg the best?
Blow up a balloon with alka seltzer
Can you blow up a balloon with alka seltzer? What else do you think might work?
You could also try an effervescent vitamin tablet or even popping candy. Which works the best?
Build a structure with marshmallows and straws
Warning – this can be a bit sticky!!
Make a marble maze
You could make a LEGO marble maze? Or use marbles inside a cardboard box.
Make a Baking Soda Volcano
The one below is made using papier mache, but you could also use sand or even snow!
Check out our baking soda volcano ideas for inspiration.
Baking Soda Reactions
Set up some simple baking soda reactions, these could be fairy themed, witchy potions or just for some fun messy play.
Make Music
Can you play a tune using water and glass bottles?
Square Bubbles
Can you make a square bubble?
How strong is a Candy House
Can you make a house from sweets? You could use different types of “glue” and see which works the best. How would you test your house?
