Science Experiment – States of Matter

Matter makes up all substances in the physical universe. Substances can exist in three states of matter: solid, liquid, or gas. The state of a substance can be changed by changing its temperature. Turning a liquid into a solid is called freezing. So, if a liquid is put in a freezer, will that always make it a solid? Let’s investigate!

This Chemical Sciences experiment allows students to investigate changing states of matter.

Students follow the scientific method to conduct the experiment, then complete the worksheets provided.
