Rhode Island World-Class Standards
RI.LS1. Life Science: All living organisms have identifiable structures and characteristics that allow for survival (organisms, populations, & species).
LS1 (K-4) FAF-4. Identify and explain how the physical structures of an organism (plants or animals) allow it to survive in its habitat/environment (e.g., roots for water; nose to smell fire).
LS1 (3-4)-4. Students demonstrate understanding of structure and function-survival requirements by...
4a. Identifying and explaining how the physical structure/characteristic of an organism allows it to survive and defend itself (e.g. of a characteristic-the coloring of a fiddler crab allows it to camouflage itself in the sand and grasses of its environment so that it will be protected from predators).
4b. Analyzing the structures needed for survival of populations of plants and animals in a particular habitat/environment (e.g. populations of desert plants and animals require structures that enable them to obtain/conserve/ retain water).
RI.LS3. Life Science: Groups of organisms show evidence of change over time (structures, behaviors, and biochemistry).
LS3 (K-4) SAE-7. Using information (data or scenario), explain how changes in the environment can cause organisms to respond (e.g., survive there and reproduce, move away, die).
LS3 (3-4)-7. Students demonstrate an understanding of equilibrium in an ecosystem by...
7a. Explaining what plants or animals might do if their environment changes (e.g., changing food supply or habitat due to fire, human impact, sudden weather-related changes).
