Plants and Pollution - Student Laboratory Kit

Plants need moisture and other key ingredients to grow vigorously and stay healthy. How do environmental pollutants (such as acid rain, fertilizers, street salt, and detergents) affect the vigor and growth of plants? What are pollutants to plants? How concentrated do pollutants have to be to affect plants? Students will experiment with different types of chemicals on radish seeds and discover answers to these questions. Teacher Notes, reproducible student handouts, and all necessary chemicals and specialized equipment are provided.

Complete for 30 students working in pairs.
