This ice activity is very simple, perfect for even very little children.
All I did was freeze a LEGO man and a dinosaur in some ice. Once frozen we felt the ice very carefully and talked about how it felt a little sticky.
We then discussed where would be the best place to put the ice for it to melt, eventually deciding to leave it in the garden with the sun shining down.
Sure enough after a few minutes the ice was no longer sticky, we tried picking it up and found it was quite slippy and very cold. Freezing was the word the children used.
This was such a simple activity, but it led to so many questions and lots of giggles.
The Science Bit
Why does water freeze?
Water can be a solid, liquid or gas. In liquid form the water particles can move around freely, so the water takes the shape of the container it is in. When you cool the water down the movement of the particles slow down and the particles become tightly packed together, which means its shape cannot change easily. We will come back to this later on and investigate in more detail.
Why is ice sticky?
Ice feels sticky because when you touch it, the ice immediately freezes the moisture in your skin, which makes the cube feel sticky.
