This is a unit on the states of matter. The concepts are taught at a very basic level since I developed this unit when teaching a self-contained special education class. There is a pre-test, many ideas and activities for teaching solids, liquids, and gases, and changing states of matter, study guide, two different levels of tests, etc. Also included are a a matter chant (which is provided in two levels for those struggling readers), and several experiment forms. Many of the activities are accompanied by pictures for the emerging readers.
This was a very fun unit to teach and there are multiple ideas that you can pick and choose from. Some of these sheets are also posted separately if you don't want to buy the whole unit.
