In this outdoor activity and game, learners collect and sort leaf samples to determine how many types of plants grow in the activity site.

Geothermal Power Plant Model
Source Institutions
In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.

Tree-mendous Plots
Source Institutions
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.

Mighty Seeds
Source Institutions
In this biology experiment, learners plant soybean seeds in plaster of Paris, witnessing firsthand the mighty power and ability of plants to grow in adverse conditions.

Glove Gardens
Source Institutions
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.

Swell Homes
Source Institutions
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.

Leaf Me Alone
Source Institutions
In this activity, learners explore the structure of plant leaves. Learners find out what happens when they coat either the top or bottom sides of leaves with petroleum jelly.

Source Institutions
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.

CD Greenhouse
Source Institutions
In this activity, learners plant seeds and watch them sprout and grow inside a CD case.

Partners in Pollination
Source Institutions
In this activity, learners identify the reproductive parts of plants and the animal (bee) structures involved in pollination.

Food Grab
Source Institutions
In this outdoor activity, learners design devices that will catch prey or gather plants.

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

Growing Food From Scraps
Source Institutions
In this activity, learners will explore vegetative propagation while preparing food scraps to grow into plants.

Attention!
Source Institutions
In this outdoor art/environmental activity, learners create designs that will attract attention to animals and plants in particular habitats, and then test whether their designs attracted the "right"

TerrAqua Investigation Column: What is the Land-Water Connection?
Source Institutions
In this investigation, learners plant seeds in a 2-liter bottle filled with soil that is connected to a water source below. Over the next few weeks, learners observe how the plants grow.

Drawing From Nature
Source Institutions
In this activity, learners draw natural objects to explore the details, differences, and similarities of natural objects.
