Ecological Interactions Activity Use the background information and the information form our lesson to complete the table in the activity packet. 10 minutes max

Ecological Interactions Activity Follow instructions for activity. Clean up at 9:00. Activity questions are due next class.

Human Impact Experiment Choose a question: How are plants affected by runoff from roads deiced with magnesium chloride in the winter? How does excess fertilizer used on farms affect plants? Air pollution causes rain to become more acidic – how might this affect plants? Are “green” cleaners actually less toxic to plants than traditional cleaners?
