Contents:

96 hands-on activities about trees, forestry, and natural resources (land, air, and water). Every activity allows students to investigate environmental issues, make informed, responsible decisions, and most importantly, learn how to think, not what to think.

Minnesota Resource Pages for activities

1. Adopt a Tree

Summary: Students “adopt” a tree, deepening their awareness of individual trees over time and encouraging a greater understanding and appreciation of their local environment.

Objectives: Students will 1) describe a chosen tree using personal observations and investigation and organize information about the tree, and 2) identify relationships between their tree and other organisms.

Subject: Science, math, language arts, visual arts, social studies

Grades: PreK-2 and 3-8

Minnesota Adopt a Tree journal

2. Get in Touch With Trees

Summary: In this activity students will explore their sense of touch and discover why touch is important to animals, including themselves.
Objectives: Students will 1) become aware of how the bark of different trees varies in texture and 2) describe a variety of textures found in leaves and other tree parts.
Subjects: Science, Language Arts, Visual Arts
Grades: PreK-6

3. The Forest of S.T. Shrew

photo: students art workSummary: By taking a "shrew's eye view" of life in the woods, your students will gain an appreciation for the variety of living things that make forests their homes, and for the variety of habitats within forests.
Objectives: Students will 1) identify microhabitats in the forest by drawing pictures or writing a story describing a microhabitat and 2) describe some of the plants and animals that characterize several microhabitats within the forest.
Subjects: Science, Language Arts, Visual Arts
Grades: 1-6

Optional supplemental resources:

4. Web of Life

photo: Girl holding bookletOverview: In this activity, students will take a close look at one particular ecosystem (a forest) and will discover the ways that plants and animals are connected to each other. By substituting the appropriate information, you can also use the activity to study other ecosystems, such as oceans, deserts, marshes, or prairies.

Objectives: Students will 1) collect information about various organisms in an ecosystem, 2) create a mural that depicts the interdependence of various organisms with other components in an ecosystem, and 3) create a simulated web of life using a ball of string.

Subject Areas: Science, Language Arts, Visual Arts

Optional supplemental resources:

  • Minnesota Web of Life information
  • Web of Life pictures This is a PDF file. You will need Adobe Acrobat Reader to download it.
  • Coniferous Biome  PDF
  • Deciduous Biome PDF
  • Prairie Biome      PDF
  • Minnesota Wetland ecosystem  PDF
5. How Big Is Your Tree?

Objectives: Students will 1) measure and compare trees and tree parts, 2) discuss how and why people measure things, including trees, and 3) explain the need for consistency in measuring.

Subject Areas: Science, Math, Social Studies

Grades: 3-8; Variation: PreK–2

Optional supplemental resources:

6. Tree Cookies

photo: tree cookieOverview: One of the best ways to learn about a tree is to look at its annual rings. Tree rings show patterns of change in the tree's life as well as changes in the area where it grows. In this activity, students will trace environmental and historical changes using a cross section of a tree trunk, or "tree cookie."

Objectives: Students will 1) identify heartwood, sapwood, and a tree's annual rings, 2) infer from a tree's rings what damage or stress might have occurred in its life, and 3) make a timeline of human history that coincides with a tree's rings.

Subject Areas: Science, Social Studies, Visual Arts, Language Arts

Grades: 3-8; Variation: 1–3

Optional supplemental resources:

7. Can it Be Real?

Overview: Students discover extraordinary plants and animals, and will gain insight on how they are uniquely adapted to environmental conditions.
Objectives: Students will 1) predict whether unusual plant and animal characteristics are real, and 2) research a plant or animal to understand how organisms are adapted to their particular environments.
Subject Areas: Science, Language Arts
Grades: 4-8

Objectives: Students will understand how leaf shapes, sizes, and other characteristics vary from plant to plant.
Subject Areas: Science, Visual Arts

10. Life on the Edge

Overview: Students will become advocates for endangered species of plants or animals and create “public relations campaigns” on behalf of these species/
Objectives: Students will 1) understand the habitat components that organisms need to survive, and 2) research an endangered, threatened or rare species and give a persuasive media presentation on preserving that organism’s needs.
Subject Areas: Science, Social Studies
Grades: 4—8
