6th - 8th Grade Module 9 Concept 1

Cycle 2

How can individuals of the same species and even siblings have similar yet different characteristics? How can we compare the different ways that traits get passed?
Cycle Summary

In this cycle, students observe the phenomenon of different traits within the same family, and use several simulations and model examples to figure out what causes the similarities and differences seen among members of the same family.

Session 6
Elicit

Students complete a probe on the passing of traits from parent to offspring.

Engage

Students observe and compare characteristics of families.

Session 7
Explore

Students toss pennies to simulate probability in connection to sexual reproduction, analyze a historical fiction text, and attempt to develop a model for inheritance in sexual reproduction.

Session 8
Explore

Students toss pennies to simulate probability in connection to sexual reproduction, analyze a historical fiction text, and attempt to develop a model for inheritance in sexual reproduction.

Session 9
Explain

Students read an informational text and watch a video to compare and contrast sexual and asexual reproduction in a Venn diagram.

Students construct Punnett squares.

Session 10
Explain

Students read an informational text and watch a video to compare and contrast sexual and asexual reproduction in a Venn diagram.

Students construct Punnett squares.

Session 11
Elaborate

Students analyze the results of a dihybrid cross model as a data set.

Students simulate the predictions and limitations of Punnett square models using bingo chips.

Session 12
Elaborate

Students analyze the results of a dihybrid cross model as a data set.

Students simulate the predictions and limitations of Punnett square models using bingo chips.

Session 13
Evaluate

Students create a paper model to describe the process of sexual reproduction, use their models from Cycle 1 and 2 to compare asexual/sexual reproduction, revisit the probe and phenomenon, and complete a formative assessment for the cycle.
