It was only three days into 1956 when three boys from Montana, out for a hike on a normal January day, made a gruesome discovery they were unlikely to ever forget. Six students take the roles of the suspects: Alex, Eric, Lisa, Olivia, Melinda and Dave. Understand that random sampling tends to produce representative samples and support valid inferences. How certain are their results? Based on the test, match the skin and blood samples. (Grades 6 - 8), Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Give each of the students the statement card and DNA profile card for their character. See https://genographic.nationalgeographic.com/genographic/index.html, Basic Biology of DNA.
