By making predictions and observations, children can learn how ice and water are related. In this activity, your child will melt ice cubes into water and will be able to explain why this happens.
Begin this activity by talking to your child about ice—describe to her how it feels, and remind her where she may have seen ice. Talk with your child about what ice is made of and how it needs to be kept in a very cold place to stay frozen.
Now fill the bowl with a tray of ice cubes. Using a clear glass bowl can help your child see through the sides as well as the top. Encourage your child to reach in and talk about how the ice feels.
Ask your child to think of what will happen to the ice when warm water is poured over the ice cubes. You can write down your child’s predictions.
Slowly add warm water to the bowl. Ask, “What is happening to the ice? What do you see?” If your child isn’t sure, explain that the warm water is causing the ice to melt. Let your child reach in and feel that the ice cubes are getting smaller and are not all frozen anymore. Keep watching or adding warmer water until all the ice cubes melt. Talk about whether your child’s predictions were accurate. Together, observe what is happening to the ice as time passes.
Key words to reinforce are freeze and melt.
