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 make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.

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

In this activity (Page 22 of PDF), learners investigate the evolution of wheat by washing different types of dough with water and comparing the results.

In this activity (Page 30 of PDF), learners investigate the evolution of wheat by conducting sedimentation tests on different flours.

In this activity (Page 25 of PDF), learners investigate the evolution of wheat by creating dough from different flours, observing the samples of dough as they rise, and then baking the dough.

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

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 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 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 environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.

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

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.

In this open-ended multicultural lab activity, learners investigate the effectiveness of herbal remedies.
