Lesson Title: Research Ecosystem
Unit Title: Save the Rain Forest
Grade: 2/3
Discipline: Science

Overview of Lesson: Students will research the term ecosystem and describe how it applies to the rain forest.

Standards: Domains of Science: Life Sciences PreK-4 5027
Demonstrate an understanding that plants and animals go through predictable life cycles. These cycles differ from species to species, but all include growth, development, reproduction, and death.
Domains of Science: Life Sciences PreK-4 5028
Observe and describe that plants and animals have different structures which serve different functions in growth, survival, and reproduction. These contribute to the well being of the whole organism, and to the success of its offspring.
Domains of Science: Life Sciences PreK-4 5030
Give examples of how different plants and animals have features that help them thrive in different kinds of places. Recognize that these features may be external, or internal, or behavioral.
Domains of Science: Life Sciences PreK-4 5039
Provide examples of living organisms meeting their needs by interacting with living and non-living parts of the environment in which they live. Observe that species are dependent on each other to maintain life. Examine ways in which the different features of each species enable it to live and reproduce in a particular environment (habitat).


Student Outcomes: Students will be able to describe how the rain forest is an ecosystem.

Length of Lesson: two half hour sessions

Instructional Mode: partner, independent activity

Multiple Intelligences: Linguistic, Interpersonal

Essential Questions: Why is it important to maintain the right balance in the rain forest?

Material / Resources Needed: balance scale, small containers, water, soil, sponge, computer

Instructional Strategies: demonstration, research

Activity or Procedure: Use a balance scale to demonstrate what happens when things are balanced and then not balanced. Fill containers with soil. Place the sponge in one container on top of the soil. Slowly pour water over the sponge until it soaks through to the soil. Slowly pour the same amount of water onto the soil in the other container. Have students observe the containers and predict what will happen when they dry out. Set the containers aside to dry out. Have students use the computer to research the term ecosystem. Later, come together to discuss what they have found out and view the dried out containers.

Assessment: Can students describe an ecosystem and relate it to the rain forest?


Evidence that Student Learning Occurred: Students will be able to explain what happens in the rain forest when an important element is removed.

Technology Skills Required or Developed:
Use input devices (e.g., mouse, keyboard, remote control) and output devices (e.g., monitor, printer) to successfully operate computers, VCRs, audiotapes, and other technologies.
Communicate about technology using developmentally appropriate and accurate terminology.
Use developmentally appropriate multimedia resources (e.g., interactive books, educational software, elementary multimedia encyclopedias) to support learning.
Work cooperatively and collaboratively with peers, family members, and others when using technology in the classroom.
Demonstrate positive social and ethical behaviors when using technology.
Practice responsible use of technology systems and software.
