Honolulu Zoo Society : Biomes

Life- Deal with It (Adapting within a Biome)

Topic Overview

Begin the Lesson

The world's biomes each have a different geography and climate. Biomes also have plants and animals. Each animal and plant has special adaptations to help them live within their home environment. Adaptations help animals eat certain foods, find water in dry conditions, stay warm in cold conditions, hide when hunting during the day, and see better when hunting during the night. Adaptations help plants find sunlight and water, and help ensure their seeds will spread and germinate.

During this WebLesson, we are going to travel the globe and visit different places to see different animals and plants in their home environments and how their individual adaptations help them survive.

Whole Class Introduction to the Lesson

You will need at least one computer with Internet connectivity and a projection device, a classroom with more than one computer, or access to a computer lab.  This introduction will take approximately 10 minutes to complete.

Show students the first segment of this episode about adaptations from  New Hampshire Public television's Natureworks, : http://video.nhptv.org/video/1492015101/

Afterwards, conduct the following class activity:

  • Ask students: What are an animal's basic needs? (food water air and shelter)
  • Ask pairs of students to select an animal (or assign animals). Have students answer: How does this animal's behavior or physical traits help it to fill these needs?
  • What would happen if your animals were moved to another biome? Choose two new biomes and explain the challenges this animal would face and physical or behavior changes that would help it survive in this new environment.
  • Use Dirtmeister's recording forms to collect and share answers. http://teacher.scholastic.com/dirtrep/animal/index.htm

As part of the introduction, you may want to review some of the glossary terms in advance of students going online. At this point you can launch the WebLesson as whole-class activity using a projection device, or you can assign students to work individually or in teams in a computer lab.

Introduction
Each biome has a certain type of geography and weather. Plants and animals cannot live just anywhere. Can you imagine a cuttlefish living on land? What about a kangaroo bounding through a rainforest? Or a cheetah racing across Antartica's frozen tundra?

Plants and animals have special adaptations (characteristics) that help them to survive and to thrive in certain biomes. In this WebLesson , you will discover how different plants and animals survive where they live.
Project
The local zoo is creating a coloring book to give to students who visit. They would like the coloring book to include a wide range of different plants and animals that live on land and in water. The coloring book must also include each of the worlds major biomes. Unfortunately, the coloring book can only have 10 pictures in it and they are having a difficult time deciding which plants and animals to include in the book and which plants and animals should go together.

Conclusion & Project
Conclusion
Earth hosts a range of environments, from dry and cold to hot and moist. The animals and plants that live in each biome have characteristics and habits that allow them to survive in that place.
Project
You are on the committee that is choosing what plants and animals to include in the Adaptation Coloring Book.

Which five plants and animals do you nominate for the book? Be sure to include land and water life, plants and animals. Briefly explain what adaptations each has and why their adaptation(s) make them remarkable.
