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.

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.
