Hey guys!!

I am due for a second assessment shortly, and i have to create an activity that involves the children investigating and exploring a certain activity. I already have an idea of using coloured ice cubes and putting them in water, therefore the children will see that the water changes colour.
I was just wondering if that would be a good idea, and if anyone had any tips for me it would be fab!! I am working with children aged 5 - 7 years old.

Thanks!!
