The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.

In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.

This modeling activity allows learners to discover for themselves what Mendel uncovered in his famous pea experiments.

This exercise can be used to stimulate the investigative nature of learners as they use forensic plant pathology techniques to prove the learners' innocence in a mock murder investigation.

In this activity, learners examine the different materials gardeners add to their soil, and discuss how these materials are important for plant growth.

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.

In this activity, learners make slides of onion cells and their own cheek cells. Use this lab to teach learners how to prepare microscope slides and use a microscope.

In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.

In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.

In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this activity related to microbes, learners make slides of cells from an onion skin and Elodea (American or Canadian waterweed) to observe under a microscope.
