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.

Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).

In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.

In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.

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.

This three-part lab helps learners understand the essential principles governing diffusion and osmosis.

An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.

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

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

In this activity, learners stain fabrics--on purpose!

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.

In this experiment related to plant biotechnology, learners discover how to prepare and load an electrophoresis gel.

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.

In this fun and in depth hands-on experiment, learners test various liquid samples (distilled water, lemon juice, vinegar, and baking soda mixed with water) to determine their pH levels and identify e
