Solids Liquids and Gases Worksheet
Water is the perfect example of matter that can change density. We know that water that is frozen is ice, water in its natural state is water and hot it becomes steam.
- Liquids do not hold a definite shape, there is not a definite volume and the particles that make up liquid move freely amongst each other but are still attracted to one another.
- Gas does not have a definite shape or volume, the particles that make up gas can move in random paths and do not attract to one another. Gas is also highly compressible.
- The last state of matter is solid. Solid have a definite shape and volume. The particles that make up a solid vibrate around fixed axes.ย

Density Activity
This printable activity is helpful for showing the various particles for each type of matter.
Each page is a jar with a lid. There are three pages that can be used to represent each of the states of matter: gas, liquid and solid. The jars are technically cookie jars, so we used cookies to show how the states of matter are.
States of Matter Activity
The gas has the least amount of cookies, the liquid has slightly more and the solid is filled. We used mini cookies, but you could use cereal, playdough or beads.ย
Kids will easily understand how this process works when they are able to make individual jars for each representation.ย
