This lesson provides two Claim-Evidence-Reasoning (CER) prompts that were developed through a collaboration between teachers at the Escobedo Middle School and the Boston Public Schools Science Department. The two prompts support student thinking as they explore the influence of environmental and genetic factors on the growth of organisms. The first prompt uses dog breeds to demonstrate the influence of genetic factors, whereas the second prompt discusses the effect of sunlight on different species of grasses to demonstrate the influence of environmental factors.
The original lesson includes possible student responses, background information, real data for prompt two, and links for additional information. A second link is provided in the performance expectation tips that includes scaffolding organizers, teacher information, and rubrics.
