5

The three lake pH's are accurate, and the two most acidic lakes are identified correctly.

5

Three to five sentences are used to describe acids found in the home and their common attributes.

5

Three to five sentences are used to describe bases found in the home and their common attributes.

5

Three to five sentences are used to explain what acid rain is. Data from Part 1 is used to discuss how each lake's location causes varying impacts of acid rain.
