Summary Students hunt for different states of matter on the school grounds Science content Chemistry: States of Matter, Properties of Materials (K-7) Lessons activity is in States of Matter and State Changes Materials Worksheet for each student: column headings are object/solid/liquid/gas Clipboard for each student Pencil for each student Procedure Discuss what a solid, liquid and gas are. A solid is hard. The particles are packed together so tightly that we cannot push through it and we can see it. A liquid we can see but the particles are further apart, so it can flow and we can move it around with our hand. A gas we cannot see as the particles are so far apart. But we can feel the particles hitting our hand (wave hand through the air). Students are given a clipboard holding their scavenger hunt worksheet, and a pencil. Students hunt around the classroom or school grounds looking for solids, liquids and gases. They write down each item and check off whether it is a solid, liquid or gas. They should try and find at least one of each state. Gather to review and discuss. Could be used as a review for older students - ask them to look around from where they are sitting and find a solid, liquid then gas. Grades taught Gr 1 Gr 2
