Have your children learn that anything that has weight and takes up space is matter. Examples include buses, tables, people, animals, and more. Use this worksheet to help them identify the objects and circle the soft, red, and small one; the liquid; and the smooth, black, and round one.
Have students look through the pics in the worksheet. Ask them what changes of state are shown, then trace the lines to the right answers. Matter can come in liquid or solid form, and changes between the two when heated or cooled (melting/freezing).
