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

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

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 (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

Build a fruit fly trap out of a 2-liter plastic bottle and some rotten fruit! Fruit flies are easy to catch in warm weather. Once you catch some, you will be able to see their life cycle up-close.

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

In this activity/demonstration, learners explore pollen and how insects and animals transport pollen. Learners investigate and compare wind and animal pollination.

In this playful activity, learners explore the structure of the cell—the basic unit of every living organism—by creating a model of cell structures using soap bubbles, and by examining a slice of onio

In this group activity, learners will explore the characteristics, functions and uniqueness of the mangrove tree.

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

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