In this online activity, learners find out whether they are smart enough to survive as a plant.

In this outdoor mapping activity, learners explore where plants grow and map plant-distribution patterns.

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 outdoor activity, learners discover how the environment around a building affects the growth of plants.

In this activity, learners help identify native and non-native plant species, learn about invasive species, and determine how native plants provide a healthier habitat.

In this activity, learners will investigate and compare the root systems of plants. Explore how weed and edible plant roots differ, and take a closer look inside with the careful use of a knife!

In this outdoor activity, learners find the swollen bumps known as "galls" on various plants and get a closeup look at the parasitic animals living inside.

In this activity, learners will dissect a pumpkin or winter squash to learn the parts of the plant. This activity gets your learner hands on with every part of the plant and will be messy.

Learners combine different plant solutions -- made from fruits, vegetables, and flowers -- with equal amounts of vinegar (acid), water (neutral), and ammonia (base).

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

In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

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

In this four-part laboratory exercise, learners investigate properties of Tobacco mosaic virus (TMV) including (1) symptoms induced by the virus in susceptible plants at the macroscopic and microscopi

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.

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

This guide outlines how to plant a garden even if you don't have a yard!

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

In this activity, learners will examine a variety of seeds, describe them, and determine how they are dispersed.

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.
