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, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

In this food science activity, learners observe different plant-originated foods.

In this plant science activity, learners conduct four experiments to observe how plants respond to sunlight and gravity.

In this "Sid the Science Kid" activity from Episode 107: My Shrinking Shoes, learners observe how plants change as they grow.

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 food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this math lesson, learners record and graph plant growth and interpret data. Learners plant seeds, and once the seeds sprout, record the change in height of the plants for several days.

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

In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.

In this activity, learners explore patterns and sequences as they observe fictional plant growth.

In this lab, learners grow broad bean (also called fava bean) plants in three EarthBoxes for a few weeks before exposing one to wind (using a fan), another to heat (using a lamp), and the third to not

In this outdoor activity/field trip, learners explore the concept of population density.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

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

In this activity learners will plant grass seed and track the growth of the grass over time.

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

Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

This exercise can be used to stimulate the investigative nature of learners as they use forensic plant pathology techniques to prove the learners' innocence in a mock murder investigation.
