MS-LS1-5 Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms.
Clarification Statement: Examples of local environmental conditions could include availability of food, light, space, and water. Examples of genetic factors could include large breed cattle and species of grass affecting growth of organisms. Examples of evidence could include drought decreasing plant growth, fertilizer increasing plant growth, different varieties of plant seeds growing at different rates in different conditions, and fish growing larger in large ponds than they do in small ponds.
Assessment Boundary: Assessment does not include genetic mechanisms, gene regulation, or biochemical processes.
This resource appears to be designed to build towards this performance expectation, though the resource developer has not explicitly stated so.
Comments about Including the Performance Expectation
Students will evaluate the effect of different environmental conditions on plant growth and compare that to the control group. Students will also discuss the impact of the environment on food production.
The educator should add to the environmental factors with genetic factors. This can be accomplished by incorporating readings on genetic engineering and comparing how each influences plants; and the food that gets to market.
