Every Drop Counts
It’s easy to waste water and even easier to take water for granted. Water pours out of our faucets as though it were endlessly available. But the truth is that the supply of good quality, fresh water is limited. Fortunately, we can all conserve water instead of wasting it. This activity will help your group cut back on water waste.

Every Tree For Itself
This fun and active modeling simulation reviews the conditions that trees need to live and grow, while also demonstrating that trees must compete to meet their needs.
Educator Lesson Plan

Fallen Log
It’s amazing how many things live in and on rotting logs. In this activity, your students will become familiar with some of those organisms by observing fallen logs or other decomposing pieces of wood. They’ll gain an understanding of how decomposition takes place and a better appreciation for microhabitats and communities.

Get Outside!
Regular and frequent time outdoors is beneficial for emotional, mental, and physical health, as well as for creativity, learning, and child development. In this activity, students will examine the physical and emotional effects of a task done outdoors versus indoors. They will design, plan, and carry out an investigation comparing the two settings, and analyze their results.

Peek at Packaging
Nearly everything we buy comes in some sort of package. Students examine the pros and cons of different packaging and design an “ideal” package.
Student Page
Poet-tree
Writing and sharing poems gives students an opportunity to express their thoughts, feelings, and beliefs in creative and artistic ways. You can do this activity in combination with Adopt a Tree, to allow students to explore their adopted tree through poetry. You may also adapt the activity to explore parts of the environment other than trees and forests, such as art or architecture.
Student Page
Signs of Fall
Students will look for signs of autumn and conduct an investigation to discover why the leaves of deciduous trees change color in the fall.
Student Page
Soil Builders
Students explore differences in soil types and what those differences mean to people and to plants. They also investigate the role soil organisms play, both in building soil and in decomposition.
Student Pages
Supplemental Materials
Tree Cookies
One way to learn about tree growth is to look at annual rings. Tree rings show patterns of change in the tree’s life, as well as changes in the area where it grows. Students will trace environmental and historical changes using a cross-section of a tree, or “tree cookie.”
Educator Lesson Plan
Student Pages
Tree Factory
By modeling the parts of a tree and creating a “tree factory,” students will learn about the structure of a tree.
Educator Lesson Plan
Supplemental Materials
Tree ID
Tree species can be identified by looking at several different features: leaves, bark, twigs, flowers, fruit, and seeds. Even the overall shape of a tree can give clues to the tree’s identity. Students learn more about trees through these identifying features. Afterward, they can play an active game that tests their knowledge of different types of trees.

Trees in Trouble
Students examine trees for signs of damage or poor health and investigate conditions that may cause trees and other plants to become unhealthy.
Student Pages
Water Wonders
The water cycle is the system by which Earth’s water is collected, purified, and distributed from the environment to living things and then returned to the environment. Through modeling and an experiment, students explore the various steps of the water cycle and make connections between the water cycle and all living things.

Web of Life
By conducting research and modeling a food web, students take a close look at a forest ecosystem and discover ways that plants and animals are connected to one another. Although this activity focuses on forests, you can also use it to study other ecosystems, such as oceans, deserts, marshes, or prairies, by substituting the appropriate information.

Decisions, Decisions
Decisions about community land use are complex and often involve many people in many ways. In this simulation, students use trees as a backdrop to develop a land-use plan.

Environmental Justice for All
Everyone has an equal right to a healthy environment—but does everyone have a healthy environment? In this activity, students propose actions to resolve various scenarios and then research issues related to environmental justice in their own state.

Exploration Energy!
The energy we use at home, school, or work enhances our lives, but it also often contributes to air and water pollution, wildlife and habitat loss, and climate change. When we reduce the amount of electricity we use—or use electricity from sources that are less polluting—we help to protect the environment and human health. Students learn about different sources of energy, conduct an audit of the electricity they use in their own homes, and create an action plan to use energy wisely.
Educator Lesson Plan
Student Page
Field, Forest, and Stream
Students conduct a field study of three different environments as they focus on sunlight, soil moisture, temperature, wind, water flow, plants, and animals in each environment. By comparing different environments, students will learn how nonliving elements influence living elements in an ecosystem.
Student Page
Forest In The City
The trees in our communities provide many benefits: they improve air quality, store carbon, and conserve energy. Trees also enhance human health by reducing blood pressure, decreasing stress, and elevating attentiveness. Students conduct a survey to investigate the social and psychological effects of the urban forest.
Student Page
Global Goods
Students gain an appreciation for how many natural resources they depend on in their day-to-day lives. By tracing the resources that go into making one item, students learn how its manufacturing can have an impact on the environment.

Improve Your Place
Every living thing has a habitat—a place that meets its needs. Human beings’ habitat is the community in which they live. Students plan and, if possible, carry out a service-learning project that focuses on making positive environmental changes in their community.
Student Page
Invasive Species
Throughout history, people have intentionally and unintentionally moved plant and animal species to new environments. Some of these species have proved beneficial, but others invade natural habitats, causing environmental and sometimes economic harm. Students research invasive species to determine how these species got to their new locations and what characteristics make their control so challenging.
Educator Lesson Plan
Student Page
Life on the Edge
Students model processes that can lead to species becoming rare or endangered. Then, they become advocates for rare or at-risk species of plants or animals and create “public relations campaigns” on behalf of these species.

Plant a Tree
Never underestimate the power of a tree! In addition to giving us an amazing array of paper and wood products, trees provide a host of other benefits—from shading our backyards to reducing air pollution to helping stabilize the global climate. Students can express their appreciation of trees by planning and carrying out their own tree-planting project.
