Evidence - What did you observe? Use the sentence stems below to answer the question with one or more complete sentences for full credit.
Looking at the pictures, I observed that there is a transformation in the appearance and composition of the forest during the fire (from a green, intact landscape to a raging, destructive blaze), which suggests a chemical change. Additionally, the presence of smoke, ash, and charred remains after the fire indicates the release of gases and the alteration of the organic matter, further supporting the occurrence of a chemical change.

The evidence of the transformation in the appearance and composition of the forest during the fire indicates that a chemical change is taking place. Chemical changes involve the rearrangement of atoms and the formation of new substances, which is evident in the visual changes observed in the forest. The release of smoke, ash, and charred remains also suggests the breakdown and transformation of organic matter through chemical reactions. These observations support the claim that a forest fire involves a chemical change.
