Curated OER
Tropism
Learners 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.
Curated OER
Plant Hormones
Students identify different plant hormones and explain their function in plant development. In this biology lesson, students investigate how IAA affect root growth. They study the history of auxin discovery.
Curated OER
Plants In Space
In this biology worksheet, students grow corn plants in growth pouches as the control group in an experiment on plant growth in microgravity. Then they analyze any differences that occur between Earth-grown and space-grown corn plants.

Science Buddies: How Do Roots Grow When the Direction of Gravity Changes?
You might not know it, but plants are able to sense their environment and actually respond appropriately. One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of...

Kenyon College: Thigmotropism in Tendrils
What is thigmotropism? Do plants have a sense of touch? What causes plants to curve toward the stimulus? Animated illustrations help to provide these answers and more. Hint: highlighting the text makes it easier to read.
