Integrated Science- Year 3 Sample Flowchart for Concept Instructional Sequence
Some solar radiation is absorbed by the Earth’s atmosphere and clouds. Some of the energy reaches the surface and is reflected. Some of the energy is absorbed by abiotic materials. Some of the energy is captured and used by living things.
How is solar radiation captured by and stored in photosynthetic producers?
Students know usable energy is captured from sunlight by chloroplasts and is stored through the synthesis of sugar from carbon dioxide. (B1f)
The universal laws of composition, motion, and energy can be applied to specific natural phenomena, i.e., the Greenhouse effect, the ozone layer, and the photosynthetic-respiratory cycles.
Instruction will include a discussion of producers and consumers, flow of matter and energy in ecosystems, and a revisit of Year 1 Biology 6e and 6f.
Students know the role of the mitochondria in making stored chemical-bond energy available to cells by completing the breakdown of glucose to carbon dioxide. (B1g)
What is the mechanism by which consumers transform glucose from plant cells into usable energy?
Students know how chemiosmotic gradients in the mitochondria and chloroplasts store energy for ATP production. (B1i)
Why are chemiosmotic gradients in mitochondria and chloroplasts important in producing ATP?
Students know how to identify reactions that involve oxidation and reduction and how to balance oxidation-reduction reactions. (C3g*)
