One of our favourite Summer activities is ice excavations, they cost almost nothing to make and keep my children busy for hours. You can set up super simple mini excavations with lego bricks or lego people frozen in ice cubes, or bigger versions and experiment with how to melt the ice.
If you have shaped moulds you could make castles and freeze princesses or superheroes. Try using a pipette or dropper and dripping warm and cold water on the ice to see if that helps it melt faster.
We sometimes add glitter or metallic shapes to make the ice look even more appealing.

How to make an ice excavation
Add water, glitter and your characters to a shaped mould.
Place in the freezer for a few hours.
Remove from the freezer once frozen and leave for a few minutes to melt a little bit, if you try to remove it straight away it’ll stick to your fingers so be careful!
Use a pipette or dropper to drop hot and cold water onto the ice, which melts it the fastest?
We love half freezing balloons to get a cave shape. Freezing a whole balloon filled with water to get a giant marble is also great fun.
Or how about making seasonal ice? One of our favourites is this Autumn themed version, but Summer themed ice filled with shells or Spring ice with flowers inside would also look lovely.
You could even make some fizzy ice like Science Sparks.
Ice Activities for Older Children
For older children try putting a bit of salt on the ice to see if that makes it melt faster.
Did you know salt lowers the freezing point of water and so makes ice melt? This is why people put down salt and grit when ice is expected on roads in winter, the salt stops the water freezing.
More Ice Activities
If it’s cold enough you could leave a water filled balloon outside and see if it freezes overnight.
How about making some ice decorations and hanging them from a tree?
