Keeping Warm Under Water
Items Needed: rubber glove
Large bowl or sink full of very cold water
Some warm water in a cup
Towel to mop up any spills
Do a simple experiment to understand the purpose of a dolphin's blubber (to help keep its body warm in cold water).
Ask your child to put his bare hand in the water. (Then dry off his hand)
Now fill the glove with warm water and tell your child to put his hand in it. (Some water will probably spill out so hold it over the bowl or sink.) Keeping his fingers pointing down tell him to put his hand back in the cold water (with the water filled glove on).
How does it feel? (This is a little how the dolphin's blubber keeps it warm.)
God designed the dolphin's body with a layer of fat, or blubber under their skin to help them stay warm in the very cold water. Scientists have also discovered that blubber helps the dolphin to swim. God was a very wise designer who made everything for a purpose.
