Leaves and Air Pollution
In this activity, students investigate the effects of automobile pollution on plant growth by making measurements on two populations of leaves, one from within 10 meters of a busy road and a population of the same species situated more than 20 meters away. They will choose a method for measuring the leaves, create a table for their data, and test their hypotheses by performing a t-test.
