Yesterday I shared a Thanksgiving science experiment explored building a boat to the Pilgrims. Today I have the second in a series of Thanksgiving Experiments to share with you It is called Do Cranberries Sink or Float?
This is the time of year that you may be a find cranberries for less than a dollar in your area around Thanksgiving. That makes now a great time to explore this Thanksgiving science experiment with cranberries.
Thanksgiving Science Experiments with Cranberries
Before You Get Started
I have created a Thanksgiving Science Cranberry Sink or Float prediction and recording sheet. You may want to print it out to use with your children.
Why Do Cranberries Float?
If you have ever been to a cranberry bog, you will notice that the cranberries float. This first experiment will explore just why they float.
Before you start this experiment, you may want to have your children predict why the cranberries float by drawing pictures and/or writing a hypothesis. I have created primary and grade school versions prediction recording sheets.
You will want to start the experiment by placing a bunch of cranberries into an empty tub.
Then you will add water to the tub. Your children will notice that as you add water to the tub. The cranberries start to float.
As you continue to add water to the tub, the cranberries will continue to rise.
Will Half a Cranberry Float?
The second experiment requires cranberries cut in half. You will then show your children the four hallow areas inside of the cranberry. Each of those sections is an air pocket. It is those air pockets that make it float.
Now that the air can get out of the cranberry still float. Your children will need to drop the halved cranberries into the water.
Have them try to come up with why the cranberries still float!
