Curated OER
Tropism
Students conduct various experiments on tropism. In this biology lesson, students explain how gravity affects the growth of plant roots. They identify the different types of tropisms.

The Importance of Tropisms
Students investigate plant tropisms using the scientific method. In this life science lesson, students learn about tropisms and test the response of corn seedlings to gravity. Response questions, extensions, and an adaptation for older...
Curated OER
Which Way to Grow?
Learners diagram and discuss the effect of gravity on the growth of plant roots. Designed to demonstrate the role that the growth hormone auxin plays in the direction of root growth. They set up the experiment to test their hypothesis...
