Recognize that plants survive through adaptations, such as stem growth towards light and root growth downward in response to gravity.
Recognize that many plants and animals can survive harsh environments because of seasonal behaviors (e.g. hibernation, migration, trees shedding leaves).
Explain how biological diversity relates to the viability of ecosystems.
- Compare and contrast monoculture with diverse ecosystems.
- Explain how biological diversity relates to the ability of an ecosystem to adapt to change.
- Explain how an adaptation is an inherited, structure, function, or behavior that helps an organism survive and reproduce.
Adaptation: A specific feature that allows a plant or animal to live in a particular environment
Behavioral Adaptation: Actions animals take to survive in their environments. Examples are hibernation, migration, and instincts.
Camouflage: A way of blending into the surroundings so that an organism cannot be seen. Also called “protective coloration.”
Characteristics: Features that make plants and animal different from each other. Examples are beak size, coloration, how animals move.
Ecosystem: a community of living orgasnisms and their interrelated physical and chemical environment.
Environment:The living and nonliving things that surround an organism.
Hibernation:When organisms become inactive for a period of time for survival, such as during cold winter months.
Migration:When organisms move from one environment to another to find food or a mate.
Mimicry: When an organism resembles the appearance, actions, or sounds of another organism.
Physical Adaptation: A characteristic in a plant or in an animal’s body that helps it to survive in its environment. Examples are protective coloration (camouflage) and the ability to retain water.
In this lesson, students will learn that evolution allows animals to develop specific adaptations to survive in their environment. They will be able to differentiate between physical and behavioral characteristics. Students will learn the importance of adaptations, and how these many adaptations enable the survival of a species.
Identify adaptations that help animals survive in various environments.
Describe plant and animal adaptations that are important to survival.
Describe the difference between pysical and behavioral characteristics.
Identify physical and behavioral characteristics.

Suggested Instructional Strategies
|W:||Explain to students that in this unit they will be engaged in several activities where they will be expected to match animals to their environments and explain why these animals are best suited for these environments. They will conduct a bird beak experiment where they will pretend to be birds using their body structures to help them adapt to their environments, and they will research other animals and how their characteristics help them survive in their environments. Finally students will design their own animal that will be adapted to a selected environment.|
|H:||Students will be engaged in a "Bird Beak Activity" where they will pretend to be using their beaks to gather food in their environment. They will also be engaged in real life examples to help them design their own animal to survive in a selected environment.|
|E:||Students will explore adaptations of multiple real life animals to identify how these adaptations help the animals survive in their environments.|
|R:||Students will answer open ended questions based on their explorations in the "Bird Beak Activity." They will be expected to apply all of their acquired knowledge to their final project of designing an animal adapted to survive in a selected environment.|
|E:||Students will express their understanding through a group presentation for a gallery walk. They will also express their understanding through thorough explanation to the open ended questions in the "Bird Beak Activity" and appropriate design of an animal in the final project.|
|T:||I will group students based on differing ability levels. I will monitor student progress throughout the activities and use questioning techniques to promote effective discourse. I will also use formative assessment to guide my instruction.|
|O:||The lesson progresses from activities where students use their prior knowledge to answer familiar questions. It then moves to hands-on and real life activities where students work in groups to develop their learning. Finally students will work independently on their final project to apply their knowledge.|
Introducing the Activity
The students will be instructed to match the animals with the environments in which the animals live using pictures from Animal Adaptations Picture Word Sort. The students will use their prior knowledge of living and nonliving things in an environment to match the animals to their environments. Although they may already know where the animals live, this activity will get them thinking about why they live there. The teacher will state, these animals need to find a habitat that allows them to survive in this environment and explain why it is best. In groups the students will match the animals to their environment. Then, together discuss why they are in this environment. Using the Animal Adaptations Word Sort PowerPoint, students will share their reasoning with a whole class discussion. The class will use their discussion to formulate a definition of adaptation.
Bird Beak Adaptation Lab
The teacher will guide a Bird Adaptation experiment, setting the purpose that animals' body structures help them adapt to their environment. This experiment will be taught by using cooperative groups in a heterogeneous setting. Before beginning the experiment, the teacher will brainstorm with the class different shapes of birds’ beaks, drawing these on the overhead or board. The teacher will then pose the question, “Why are there different shapes of beaks?” She will then draw students' attention to the Bird Beak Adaptation Lab report. The teacher will clarify any questions about the table at this time. The teacher will give each group the supplies listed in the Bird Adaptation Materials List. She will then instruct the students to use each tool to gather the various foods and record their observations on their table. Once the groups have been given ample time to complete their table, the teacher will discuss their findings as a whole class. She will then ask the students to independently answer the open-ended questions listed at the bottom of the lab report. Teacher will guide the class in a discussion of the open ended questions, leading students to see that the shape of a bird's beak (the tools) is directly related to the environment that it lives in and the food it is able to acquire. The expectation is that the students will discover which tools (beaks) work best to gather food for survival and understand that this is an adaptation for birds to survive in their environment.
Physical and Behavioral Adaptations Chart
Teacher will use the Animal Adaptations PowerPoint to introduce other animal adaptations. Through class discussion, teacher will draw student attention to the difference between physical and behavioral adaptations. Students will again be placed into their heterogeneous cooperative learning groups where they will be assigned one of the animals from the Physical and Behavioral Adaptations chart to research using the Animal Adaptations Facts. Groups will be required to create a presentation on chart paper illustrating their animal's adaptations. Upon completing presentations on chart paper, groups will take a gallery walk where they will walk around the room and review other groups' presentations to learn about other animals' adaptations. The class will then come back together to complete the Physical and Behavioral Adaptations Chart.
Students will design an animal that could survive in the environment they selected from the environment cards. The animal design must include at least 2 physical adaptations that enable the animal to survive in its environment, at least 1 behavioral adaptation that enables the animal to survive in its environment, and a description of how each adaptation enables the animal to survive. Students will also be required to draw and name their designed animal. Teacher can check student understanding by using the Animal Adaptations Final Project Rubric.
Throughout the lesson, use entrance and exit slips to check for understanding. Encourage students to explain the concept they learned that day. Use a Gots and Needs chart where students post what they got from the lesson, and what they still need to further their understanding.
Observe student performance on the Tundra Probe Activity. Collect and assess the probe. The information each student presents will show you whether the student understands the concept of adaptations.
Use the teacher created quizzes (adapted and regular version) to gauge student understanding. If you find students are repetitively missing a certain question, go back reteach that concept.
