Digital Agenda February 24: Speciation Cornell Notes

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.

Objectives 

1. Students will describe how a species of organism can split off into a separate species by completing the Speciation Cornell Notes with a 3 or better.

Genetic Drift

Answer the following Questions from the video:
1. Why are all domesticated dog breeds considered the same species, even though they look very different?
2. Can two different species mate and have offspring? Give an example.
3. When does speciation happen?
4. When does Allopatric Speciation occur? Give an example.
5. Why can populations that become separated form different species?
6. How many generations do YOU think it takes for a species that becomes separated to become two separate species? (not in the video, estimate and explain why)
7. How can behavioral isolation separate organisms in the same area in Sympatric Speciation? Give an example.
8. Why are the Eastern Meadowlark and the Western Meadowlark considered different species even though they look the same?
9. Explain how habitat isolation can result in an organism becoming a different species.
10. What are the three things that the video reminds you of at 5:45?
11. Explain why isolation is not the mechanism that causes organisms to change over time.
12. Explain what DOES cause populations to change over time.

Summary
Today I learned... (can be bullet points, sentences, or drawings)



Cornell Notes Criteria for success:
- Notes are set up in Cornell Note format
- All vocabulary is defined in student friendly language (not copied from google)
- 11 or more of the questions are answered fully AND correctly, using information and examples from the video
- A summary of what was learned is at the bottom, using 2-3 complete sentences.

4= All success criteria is met
3= 3/4 success criteria is met
2= 2/4 success criteria is met
NP = none of the success criteria is met

When you are finished YOU MAY...

1. Watch THIS PLANET EARTH 2 Episode about Jungles, and try to spot the different adaptive traits that you see 

4. YOU MAY ALSO:

-watch THIS DOCUMENTARY about human evolution

- watch THIS DOCUMENTARY about how the theory of evolution has changed through time to become more accurate.

-  Play the first level of the evolution game 

- Play the fossil sorting game
