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

In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

Dig a hole, line it, fill it with fresh water, and you have a water hole: a good place to study colonization.

In this activity, learners explore how to protect their skin while applying pesticides to plants.

In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

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

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

In this activity, learners create a garden in a disposable glove. They learn about the conditions necessary to make the seeds sprout and actively participate in caring for their plants.

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 biology activity (page 3 of the PDF), learners will explore how plants turn sunlight into food through a process called photosynthesis.

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

In this hands-on botany activity, learners sprout vegetables in film canisters.

Millions of organisms can live in and around a body of water.

This laboratory exercise is designed to show learners how DNA can easily be extracted from onion cells. It includes an optional test for the presence of DNA.

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 fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.
