MS-LS1-5: Environmental and Genetic Growth Factors

Construct a scientific explanation based on evidence for how environmental and genetic factors influence the growth of organisms. (Cause and Effect)

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.


The following assessments were created by science teachers hoping to better understand the NGSS. In most cases teachers went from standard to assessment in around an hour.  These are drafts and should be used accordingly. Feel free to improve these assessments or contribute to the collection. Learn more about assessment design here.




Environmental factors (e.g. food, light, space, and water)
Genetic factors (e.g., specific breeds of plants and animals and their typical sizes)
Growth of organisms
Cause and Effect
