In the kitchen, learners can perform their own density investigation.

In this activity, learners measure the amount of carbon dioxide in a carbonated drink.

In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.
