The activity that the student could perform to model the physical weathering of rock is to place drops of acid on chalk and then observe the chemical reaction.
Explanation:
Physical weathering refers to the process of breaking down rocks into smaller pieces without changing their chemical composition. To model this process, the student can take a piece of chalk (which is similar in composition to some types of rocks) and apply drops of acid onto it. The acid will react with the components of the chalk, causing it to break down and crumble. By observing this chemical reaction, the student can gain a better understanding of how rocks can be physically weathered through chemical processes.
