Question

name ____________ date ____________ sort it: physical vs. chemical changes cut, sort and glue the changes in matter under the correct column. physical changes in matter chemical changes in matt water freezing burning wood baking a cake exploding fireworks rotting bananas iron rusting breaking glass boiling water ice melting crushing a can digesting food chopping wood photosynthesis cooking an egg mixing sugar and water

Explanation:

Step1: Identify Physical Changes

Physical changes are changes in state or shape without new substances. So: Water Freezing (state change), Ice Melting (state change), Boiling Water (state change), Breaking Glass (shape), Crushing a Can (shape), Chopping Wood (shape), Mixing Sugar and Water (dissolving, no new substance).

Step2: Identify Chemical Changes

Chemical changes form new substances. So: Burning Wood (combustion), Baking a Cake (chemical reactions), Exploding Fireworks (reaction), Rotting Bananas (decomposition), Iron Rusting (oxidation), Digesting Food (enzymatic reactions), Photosynthesis (reaction), Cooking an Egg (protein denaturation).
