Lesson Title: Winter Adaptations
Discipline Focus: Life Science
Grade level: 7th Grade
Length of lesson: One class period

                           Stage 1 – Desired Results
Academic and Content Standard(s):

National Science Education Standards:
Life Science – M.C.4 Populations and ecosystems

Minnesota Academic Standards for Science 2009:
Life Science-Interdependence among Living Systems-Flow of energy and matter
Benchmark Code: 7.4.2.2.2 - Describe the roles and relationships among producers, consumers
and decomposers in changing energy from one form to another in a food web within an
ecosystem.

Life Science-Evolution in Living Systems-Variation
Benchmark Code: 7.4.3.2.3 - Recognize that variation exists in every population and describe
how a variation can help or hinder an organism’s ability to survive.

Understanding (s)/goals:                    Essential Question(s):

Students will understand:                            How is energy transferred between
                                                      organisms?
      Winter adaptations.                           How do organisms adapt to their
      Food webs.                                     environment?
                                                     What special adaptations enable organisms
                                                      to survive winter conditions?

Student objectives (outcomes):

Students will be able to:

      Describe winter adaptations of organisms.
      Create a food web.

                              Stage 2 – Assessment Evidence
Performance Task(s):                       Other Evidence:

      Discuss adaptations and body                 Completion of adaptation table.
       regulation of organisms.
      Design a food web based on
       organism observations.

                                  Stage 3 – Learning Plan
Learning Activities:

   Materials and Resources:

       Student handouts

   Introductory Activities:

       Winter Adaptations
       Ask students how organisms are able to survive and reproduce in constantly changing
       outer environments like Minnesota winters.

       Creating a Food Web
       Have students make outdoor observations about organisms.

   Developmental Activities:

       Winter Adaptations
       Have students think about some Minnesota organisms and complete the table for each
       organism in regards to winter adaptations and body regulation.

       Creating a Food Web Student Directions
          1. Spend some time outside looking for plants, animals, and evidence of animals
              (tracks, browsing, nests, galls, scat, etc.). Note what you see. You will use these
              plants and animals to assemble a food web.
          2. Cut out the rectangles on the next page. On each rectangle, draw a plant or
              animal for which you’ve seen evidence outside. Label the organism with its name.
          3. Arrange the plants and animals into a food chain. You must include and label
              each of the following: a producer, primary consumer, secondary consumer, and
              tertiary consumer. Glue your food web to the colored paper. Draw arrows to
              indicate the direction of energy flow.
          4. Use the remaining two rectangles to add a decomposer and a parasite to your
              food chain, label them, and draw arrows to indicate energy flow. You don’t need
                        Graduate Fellows in K-12 Education

         to have seen evidence of these, which is tough in the winter. Instead, use some
         we talked about in class.
      5. Cut out the arrows on the next page and place them where appropriate on your
         diagram to show relationships between organisms.
      6. Fill out the table below. For each organism, describe the evidence you saw, and
         give its place in your food chain (for example: producer, primary consumer, etc.).
         You will need at least four organisms, but if you see more please add them.

Closing Activities:

   Discuss the activity results.
