Guiding Questions What is the Sun’s role in the process of photosynthesis? What type of energy conversion occurs during the process of photosynthesis? What are the products and reactants in the process of photosynthesis? Why is photosynthesis necessary for life on Earth? Why is photosynthesis necessary to sustain life? Vertical Alignment Expectations *TEKS one level below* 6.2C collect and record data using the International System of Units (SI) and qualitative means such as labeled drawings, writing, and graphic organizers 5.9B describe how the flow of energy, used by producers to create their own food, is transferred through a food chain and food web to consumers and decomposers *TEKS one level above* 8.2C ​collect and record data using the International System of Units (SI) and qualitative means such as labeled drawings, writing, and graphic organizers BIO B.9B compare the reactants and products of photosynthesis and cellular respiration in terms of energy and matter. Sample Assessment Question Which molecule in the photosynthesis equation represents food energy made by plants? A Carbon dioxide B Water C Glucose D Oxygen Plants undergo photosynthesis, which helps them grow. How does sunlight affect the process of photosynthesis? A. It encourages rain, which provides the water needed for growth. B. It warms the leaves of plants, which allows the reaction to occur quickly. C. It provides solar energy, which plants use to drive the reaction. D. It increases the air temperature, which creates energy. The resources included here provide teaching examples and/or meaningful learning experiences to address the District Curriculum. In order to address the TEKS to the proper depth and complexity, teachers are encouraged to use resources to the degree that they are congruent with the TEKS and research­based best practices. Teaching using only the suggested resources does not guarantee student mastery of all standards. Teachers must use professional judgment to select among these and/or other resources to teach the district curriculum. Some resources are protected by copyright.

Ongoing TEKS 7.4A Knowledge and Skills with Student Expectations District Specificity/ Examples Vocabulary Suggested Resources Resources listed and categorized to indicate suggested uses. Any additional resources must be aligned with the TEKS. Process Skills: 7.2 Scientific investigation and reasoning.​ The student uses scientific inquiry methods during laboratory and field The student will learn how to gather and record data during investigations in their science notebook. STEMscopes Process Skills investigations. The student is expected to: (C)​ collect and record data using the International System of Units (SI) and qualitative means such as labeled drawings, writing, and graphic organizers Subtopic: Photosynthesis 7.5 Matter and energy. The student knows that interactions occur between matter and energy. The student is expected to: *CISD Safety Net* (A)​ recognize that radiant energy from the Sun is transformed into chemical energy through the process of photosynthesis *Links to Readiness Standard *Bloom’s Level­ Analyze The student will learn that a plant needs H2O, CO2, and light from the sun to make glucose as food and produce oxygen. Questions and Stems: ● Why does photosynthesis need light energy from the Sun to complete the process? ● What happens when light (energy) from the Sun is used for the process of photosynthesis? ● Why is photosynthesis necessary to sustain life on Earth? Teacher Notes: ● Students learned about photosynthesis in fifth grade. Sixth grade does not cover photosynthesis. ● Make sure students understand the flow and transformation of energy. ● Elodea can be purchased at a pet store that has aquariums and green potato vine is great to see stomata Chemical Energy Photosynthesis Radiant Energy Children’s Literature: Activities: PPT Photosynthesis PPT Notes Stomata and Chloroplast Notes Student Stomata and Chloroplast Notes Teacher Plant exploration lab Websites: Photosynthesis song Illuminating photosynthesis BrainPOP photosynthesis and respiration BrainPOP photosynthesis E­learning for photosynthesis Chloroplasts Elodea and chloroplasts Stomata Lessons: Textbook: Photosynthesis pgs 42­45 Photosynthesis Textbook worksheet STEMscopes 7.5A ● Photosynthesis is a good base to refer back to all year in the 7th grade curriculum. Idea being that the sun's energy creates the process of photosynthesis which produces the sugar glucose that all life depends on for energy. Additional Vocabulary Needed for Understanding: glucose, transform, transpiration, chlorophyll, chloroplast, respiration, xylem, phloem Background/Extra Information:
