Product Details

Looking for a creative way to teach evolution? Study seed evolution by making histograms! Evolution often conjures mental images of monkeys to cavemen to modern humans. In reality, evolution can be studied on a much simpler scale. Measure mass and length of sunflower seeds to see how such traits are selected in nature. Histograms created from the data allow students to analyze the frequency and symmetry of distribution and draw conclusions about the natural selection of seed size.Complete for 30 students working in pairs. Five calipers are included for student groups to share. Additional calipers are available separately.

Performance Expectations

MS-LS4-4. Construct an explanation based on evidence that describes how genetic variations of traits in a population increase some individuals’ probability of surviving and reproducing in a specific environment.
MS-LS4-6. Use mathematical representations to support explanations of how natural selection may lead to increases and decreases of specific traits in populations over time.
HS-LS4-3. Apply concepts of statistics and probability to support explanations that organisms with an advantageous heritable trait tend to increase in proportion to organisms lacking this trait.
HS-LS4-4. Construct an explanation based on evidence for how natural selection leads to adaptation of populations.
