Ice
How can I manipulate the properties of ice?
Experiment 1- Rescuing a trapped toy!
You will need:
- A container
- A toy
Instructions:
- Fill your container with water and pop your toy in
- Set it overnight
- Work out how to rescue your toy
Next steps:
How can you get your toy back? Can you heat it up? Where is somewhere warm in your house? Could you smash the ice with a tool? What is the fastest way to save your toy?
Experiment 2- Making Frozen Treats!
You will need:
- Ziplock bags
- Yoghurt or cream
- Ice cubes
- Something to sweeten it up like fruit
Instructions:
- Add the yoghurt and sweetener into a ziplock back and seal it tightly
- Place this inside another bag which contains ice and salt
- Shake the bag and leave it to set for a few minutes
- Enjoy!
Next steps:
How does this reaction work? How does the yoghurt freeze so quickly? Would this work as well if we didn’t use salt? Which flavour is the best and why?
