Ecosystems (4 Weeks)
S4L1. Obtain, evaluate, & communicate information about the roles of organisms & the flow of energy within an ecosystem.
a. Develop a model to describe the roles of producers, consumers, & decomposers in a community.
b. Develop simple models to illustrate the flow of energy through a food web/food chain beginning with sunlight & including producers, consumers & decomposers.
c. Design a scenario to demonstrate the effect of a change on an ecosystem.
d. Use printed & digital data to develop a model illustrating & describing changes to the flow of energy in an ecosystem when plants or animals become scarce, extinct, or over-abundant.
Water (4 Weeks)
S4E3. Obtain, evaluate, and communicate information to demonstrate the water cycle.
a. Plan and carry out investigations to observe the flow of energy in water as it changes states from solid (ice) to liquid (water) to gas (water vapor) and changes from gas to liquid to solid.
b. Develop models to illustrate multiple pathways water may take during the water cycle (evaporation, condensation, and precipitation).
