2nd Grade Science Unit 9

Big Idea:

Understand how animals and plants depend on each other and their environments.

Student Expectations:

Priority TEKS

2.9(C) compare and give examples of the ways living plants and animals depend on each other and on their environments such as food chains

Focus TEKS

2.9(A) [Readiness] identify the basic needs of plants and animals

2.9(B) [Supporting] identify factors in the environment, including temperature and precipitation, that affect growth and behavior such as migration, hibernation, and dormancy of plants and animals

2.3(A) [Ways to Show] identify and explain a problem in his/her own words and propose a task and solution for the problem such as lack of water in a habitat

2.2(C) [Ways to Show] collect data from observations using scientific tools;

Ongoing TEKS

2.4(A) [Tools to Know] Collect, record, and compare information using tools, including computers, hand lenses, rulers, collecting nets, notebooks, and materials to support observations of habitats of animals and plants such as terrariums and aquariums.

2.1(A) [Tools to Know] Identify and demonstrate safe practices as described in the Texas Safety Standards during classroom and outdoor investigations, including wearing safety goggles, washing hands, and using materials appropriately.

2.2(D) [Ways to Show] Record and organize data using pictures, numbers, and words;

2.2(E) [Ways to Show] communicate observations and justify explanations using student-generated data from simple descriptive investigations; and

2.2(F) [Ways to Show] compare results of investigations with what students and scientists know about the world.

Student Learning Targets:

• I will create a food chain to show how plants and animals depend on each other.
• I will identify how the environment affects plant and animal behavior.
• I will write a solution to a challenge a plant or animal might encounter in their environment.

Essential Questions:

• How do plants and animals need one another?
• How are living things adapted to their environment?
• Can plants survive in different environments?
• How do organisms use their physical characteristics to meet their needs?
