You will explain adaptations to environments allows certain individuals to survive in environments. Over time, the most favorable traits are passed on through natural selection.
1. Explore the virtual simulation . . .
- While you were interacting with the simulation activity, explain the relationship between the dominant and recessive genes when adding a mutation. What did you notice?
- Elaborate on what you explored during the activity. Minimum of 3 complete sentences.
2. Watch the video . . .
- What is natural selection?
- Who was Charles Darwin?
- What are some factors that contribute to how species change over time?
- Write a summary of the video. Minimum of 4 complete sentences.
3. Investigate the presentation to learn more about natural selection ! ! !

- In your own words create a definition for natural selection.
- What was Charles Darwin’s theory about why the finches in the Galapagos Islands have different sized beaks?
- The sharp-beaked ground finch and the large ground finch both eat mostly seeds. Predict why they have very different beak shapes.

- You will select a living organism and create your own natural selection example poster. Click on the link to look at some examples. https://www.iroquoiscsd.org/Page/6335
- You will record or provide an image of yourself with the project.
- You will then write a one page reflection on your experience with the project.
Introduce your project.
What did you learn?
Explain your natural selection scenario!
What causes organisms to change over time?
Standard:
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.
Essential Question:
