In this pack, you have materials for 2 different “States of Matter Guess Who?” game boards. These work wonderfully in the context of a “States of Matter” science unit as learning or review games. When playing these games, students practice vocabulary and classification as they identify items as solids, liquids, and gases. They also have to break down each category of solid, liquid, and gas more specifically by asking questions about the item’s characteristics/properties. These games are great for a whole class activity, small group work, or partner work.
