In this lesson, students explore the impact of environmental changes on an organism's allele frequency.
Step 1 - Inquire: Students watch a video on peppered moths and identify vocabulary related to allele frequency.
Step 2 - Investigate: Students play a game to understand allele frequency changes that can occur in species impacted by changing environments.
Step 3 - Inspire: Students explore how climate change is impacting native Arctic communities and complete a project describing how climate change is impacting animals in the Arctic.
This lesson could be used in an environmental science or biology class.
This lesson could be used to supplement a variety of curricular topics such as genetics, population dynamics, or climate change.
Students should have some prior knowledge of genetics.
To prepare in advance for the game in the Investigate section:
Print and cut out the organisms cards.
Be sure to have on hand one large white sheet of paper or tarp and one large black sheet of paper or tarp.
Teacher can make any of the following adjustments to the game in the Investigate section:
Use the third slide of the Game Cards to add organisms and allele frequencies
Assign different students to be the predator for each round
Add additional camouflage to the sheet such as leaves or other decoy organisms
Add additional student predators to the activity by having the predator have offspring
Higher-level students can investigate further by researching the albedo effect and how albedo is changing as a result of ice melt.
In this lesson, students get to learn about the genetic diversity of species in the Arctic ecosystem and how climate change has upended the region. Additionally, students get to learn about how to compute allele frequencies and percentages and provide explanations on why certain species are less suitable to survive in their habitats taking into account the impact of climate change. This lesson also builds students' capacity to advocate for protecting sensitive ecological hotspots in the Arctic. This lesson has been thoroughly reviewed and is recommended for teaching.
