Lesson Title: Basic Needs Credit: Teacher’s Domain: http://72.32.11.171/resources/tdc02/sci/life/colt/lp_stayalive/index.html Overview In this lesson, students watch video clips of animals and plants in their natural environment, to gather evidence that all living things have basic needs that must be met in order to survive. Then, to illustrate their understanding of this concept, students draw pictures of real or imaginary pets eating, drinking, breathing, and taking shelter (from the elements or from other animals). Objectives
TEKS: 6.8 Science concepts. The student knows that complex interactions occur between matter and energy. The student is expected to: (C) Science concepts. The student knows that complex interactions occur between matter and energy. The student is expected to: 6.12 Science concepts. The student knows that the responses of organisms are caused by internal or external stimuli. The student is expected to: (A) identify responses in organisms to internal stimuli such as hunger or thirst; (B) identify responses in organisms to external stimuli such as the presence or absence of heat or light 7.8 Science concepts. The student knows that complex interactions occur between matter and energy. The student is expected to: (B) identify that radiant energy from the Sun is transferred into chemical energy through the process of photosynthesis. 7.9 Science concepts. The student knows the relationship between structure and function in living systems. The student is expected to: (B) describe how organisms maintain stable internal conditions while living in changing external environments 8.11 Science concepts. The student knows that traits of species can change through generations and that the instructions for traits are contained in the genetic material of the organisms. The student is expected to: (A) identify that change in environmental conditions can affect the survival of individuals and of species Suggested Time

Background Information In order to survive, animals need air, water, food, and shelter (protection from predators and the environment); plants need air, water, nutrients, and light. Every organism has its own way of making sure its basic needs are met. It is important that young children be given the opportunity to recognize these needs by observing and then describing the natural world. The Lesson Part I 1. Have students brainstorm answers to the following questions: · What do living things need to stay alive? · What do you need? What do your pets need? · What do plants need? Record students' answers on easel paper or on the chalkboard. 2. Show students the What Do Animals Eat? video. Ask: · Why do animals need to eat? · What kinds of things do they eat? · Do all living things eat? · Do plants eat? Explain that animals need to eat for energy; plants don't eat but they still need energy. Ask: · Where do plants get energy? 3. Distribute the handout. Have students watch the Beavers video. Have students record the needs of the beavers as they watch the clip. 4. Discuss the following questions: · What do beavers need to stay alive? · Where do they get what they need? · What changes do beavers make to their environment? · How do the beaver's activities help other organisms living in the same environment? Part II 5. Have students watch the Biome in a Baggie video. Tell them to look for things that plants need to stay alive. Have students watch the Photosynthesis video. Then have them answer the two related questions on the handout. Encourage them to watch the video multiple times. 6. Discuss the following questions: · What do plants need to stay alive? · Where does their food (energy source) come from? · How do plants absorb water? · What things do plants need that animals don't? · What things do animals need that plants don't? · How do you know plants are living things? 7. End this part of the lesson by asking students whether they want to make any changes to the list of basic needs compiled at the start of the lesson (in Step 1). 8. Both plants and animals need air. To help students understand that plants need carbon dioxide (a gas that animals exhale) and that animals need oxygen (a gas that plants produce), have students explore "The Cycle" feature within the Illuminating Photosynthesis Web activity. Focus on the gases plants and animals need, not on understanding the process of photosynthesis. Have students explore the Web activity with a partner and work together to complete the handout. 9. Distribute white paper and markers to students. 10. Review the needs of living things. 11. Have students draw a picture of a real or imaginary pet. Tell students to show their pet enjoying food, water, air, and shelter -- having all its needs met. Label the "needs" represented in the drawing. |
