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 activity related to plant biotechnology, learners use the tissue culture process to rapidly produce clones (genetic copies) of a particular plant (cauliflower, rose cuttings, African violet le

In this activity, learners will make seed orbs to grow new trees and plants. Learners will explore ecology and life cycles as well as stewardship through this activity.

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

In this online game, learners must purchase power plants for their city.

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

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

In this activity, learners explore how engineers work to solve the challenges of a society, such as efficient planting and harvesting.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

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

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

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

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

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, learners try to revive wilted celery. Learners discover that plants wilt when their cells lose water through evaporation. Use this activity to introduce capillary action.

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

In this biology/ecology activity, learners construct a terrarium out of a tennis ball container. This terrarium is unique because it never has to be watered.

In this two-day activity (on pages 16-22), learners use a process like that of the Yoruba people of Nigeria to create an African symbol on cloth.

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

In this lesson plan, learners examine some of the of greenhouse gas emissions sources in their community.
