Major                 Plants are an important natural resource providing food, oxygen, and useful
Understanding         products that benefit humans and nature. Plants go through an orderly cycle of
                      growth. An inquiry into the usefulness of plant products and the life cycle of
                      bamboo will heighten students’ awareness of the need for responsible use of
                      natural resources.

Grade/Subject         Grade 2; Biology & Environmental Science

Objectives                  Distinguish between natural and man-made resources and understand
                            that natural resources are limited.
                            Demonstrate understanding that plants produce oxygen, food, are a
                            source of useful products, and provide benefits in nature.
                            Identify important plant products (fiber, cotton, oil, spices, lumber,
                            rubber, medicines, and paper).
                            Identify and describe changes in a plant life cycle from seed to seedling
                            to flower (blossom) to fruit.
                            Identify plants as a food source for humans and animals and provide
                            examples.
                            Count by fives and compare two whole numbers.

Instructional         1. Anticipatory Set: The Giving Tree
Strategies
                          1.1. Read the excerpt from The Giving Tree by Shel Silverstein. Discuss
                               things the boy received from the tree (shelter, food, oxygen,
                               entertainment). Explain that trees are a natural resource. Natural
                               resources are plants, animals, water, air, land, minerals, forests, and
                               soil. Tell students we can protect our environment by not wasting our
                               natural resources. Today’s lesson will investigate plants as a natural
                               resource.

                      2. Activity: What Comes from Plants?

                          2.1. Have students complete the Plant Products Worksheet. Remind
                               students that many products we use every day come from plants (see
                               worksheet answer key). Discuss students’ responses after completing
                               the following activity. As you review students’ answers, note that all
                               the products are natural resources and name the source of the product.

                          2.2. Pass out Giving Tree Leaves to students. Place the giving tree model on
                               the board. Have students place leaves on the tree branches if the
                               product listed comes from a plant. Review student choices and make
                               changes, if needed. Plants provide important products: fiber, cotton, oil,
                               spices, lumber, rubber, medicines, and paper. These are natural
                               resources that need to be used responsibly because they are limited.

                      3. Activity: How Does Your Plant Grow?

                          3.1. Review the basic parts of a plant using the plant model. Briefly
                               describe the basic function of each part of the plant.

                          3.2. Provide each group of students with a Life_Cycle Cards set. Instruct
                               students to order the life cycle of the plant. Discuss the life cycles of
                               the various plants.

                      4. Activity: What is Bamboo?

                          4.1. Show students bamboo model and discuss basic structure. Allow
                               students to investigate the hollow stem and unique strength of bamboo
                               specimen. Tell students that bamboo is a grass.

                          4.2. Use the Bamboo Life Cycle card set to discuss bamboo’s rapid life
                               cycle. Most bamboo can be harvested in less than a year. Compare the
                               bamboo life cycle to the life cycle of the loblolly pine. A loblolly pine
                               needs fifteen years to grow large enough to harvest. Show the two-inch
                               model of the pine tree that represents one month of growth. Discuss
                               why a rapid life cycle supports a sustainable resource.

                          4.3. Provide each group of students with bamboo specimen, measuring tape,
                               and a Bamboo Growth Chart worksheet. Students will measure the
                               specimen and determine the age of the bamboo. Students may need to
                               estimate the growing period. Growing environment and species affect
                               growth rate. Growth chart is based on Phyllostahcys Moso bamboo.

                          4.4. Allow students to observe and investigate the products made from
                               bamboo. Discuss unique traits of bamboo as it pertains to the different
                               products. See background information for detail.

Practice              1. The day in the life of a flower: View the film on plant growth at
                         www.brainpop.com. Students will create a life cycle chart of a flower by
                         correctly ordering the stages from seed to blossom.

                      2. My Giving Tree: Students will create their own tree out of brown paper.
                         Students should write products derived from plants on leaves. Pictures of
                         products may be pasted on leaves.

Closure               Review with students the importance of plants as a natural resource. Review
                      the orderly stages of the plant life cycle. Remind students that both living and
                      nonliving resources must be used responsibly to ensure an ample supply.

Extensions            1. Natural Resources Scavenger Hunt: Have students search for natural
                         resources products at home. Compare the students’ results as a class.
                         Classify the findings as plant or animal resources.

                      2. Can you eat bamboo? Review plants’ role in providing survival needs for
                         animals (food, oxygen, shelter). Let students know that in Asian countries
                         bamboo is abundant and used as a food source for animals and humans.
                         Allow students to sample bamboo shoots. Panda bears’ primary diet is
                         bamboo. Have students name other animals whose diet is primarily grass.
                         Students will create a pictorial report on an animal that is a herbivore.

                      3. Paper Table Challenge: Modeling the structure of bamboo, challenge

                         students to create sturdy tables out of paper and tape. Limit the constraints
                         on design. Place students in groups and provide each group with ample
                         paper and tape.

                         Challenge: Table must support one book and stay an inch from the floor.
                         Additional books may be added to test the strength of the table. See further

Teaching Tips         Bamboo products can be purchased at most stores that sell home goods and
                      clothing. Bamboo invasively grows in several locations in the Richmond area.
                      www.WillisOrchards.com and www.bamboogarden.com are online nursery
                      resources that sell bamboo varieties.

                      The Giving Tree by Shel Silverstein can be purchased at local bookstores.
