Learners will create a simulation of the chemical reactions that occur during the digestive process. A physical change occurs when the appearance of matter changes, but the composition of the matter does not change.

Students form a variety of categories for seed mixes (wild bird seed or 15 bean soup) and create graphs to display their categories.

Young scholars observe that water has weight and that weight decreases as water evaporates. The changes that occur as a sponge dries on a yardstick balance illustrates this concept.

The relative weight of water, in different types of containers, is explored.

Young scholars use a globe and cups of water to illustrated the amount of water versus land on earth and the amount of fresh versus salt water available to plants and animals.

Students observe water changing states from a solid to a liquid to a gas.
