Evolution

ASSIGNMENT:

1. Read the article above on snakes or the one on birds

2. Write a 3-5 sentence summary or reaction to the article.

3. What evidences in the article you read support the theory of evolution?

ASSIGNMENT:

1. Watch the above videos on different scientists and their contributions to evolutionary theory.

3. After the video, see me for a copy of Lamarck v Darwin statement comparison.

ASSIGNMENT:

1) See me for a copy of fill-in notes on natural selection.

2) Watch the video on natural selection and complete the notes.

ASSIGNMENT:

1) See me for a copy of fill-in notes on genetic drift.

2) Watch the video on genetic drift and complete the notes.

ASSIGNMENT:

1) Write a one-sentence explanation of how gene flow contributes to genetic variation in populations.

ASSIGNMENT:

1) See me for a copy of fill-in notes on speciation.

2) Watch the video on speciation and complete the notes.

ASSIGNMENT:

1. Open the link for the Pepper moths simulation above and make observations about the changes in the moth population in each of the environments. You will need to select "Bird's Eye View" from the menu on the bottom of the screen to complete the interactive portion of the activity.

2. Would this be disruptive, stabilizing or directional selection? Tell me your thoughts before moving on by writing a 3-5 sentence summary of your observations. Your explanation should indicate whether the model was showing disruptive, stabilizing or directional selection and why. Also include a sentence about survival of the fittest. Which moths were more fit in which environments and why?

1. Complete the natural selection lab above to determine how evolution causes changes in allele frequencies.

2. See me for a copy of the table you will fill in during the lab.

3. Then, use the instructions on the left side of the screen to complete the virtual lab to fill in your data table.

4. Last, click on the journal icon and answer the journal questions-using complete sentences- on your paper.

ASSIGNMENT:

1. Fold your paper in thirds.

2. Label the top of the sections: "Structural Evidence", "DNA/Biochemical Evidence" and "Direct Observation".

3. Watch the video above and take notes on the different types of evidence that support the theory of evolution.

4. When you are done with your notes, see me for a hands-on activity looking at some structural evidence for evolution.

ASSIGNMENT:

1. Open the link above and complete the online activity.

2. Use 3 index cards. Write: "homologous structures" on one card, "vestigial structures" on another card and "analogous structures" on the last card. The activity will teach you about homologous structures and analogous structures. Use the activity to define and draw an example of each on the index card.

3. Then use the internet to research vestigial structures. Define and draw an example of a vestigial structure. What vestigial structures do you have in your body?

ASSIGNMENT:

1. Click on one of the websites above to go through an Evolution lab. You will complete a series of virtual labs looking at relatedness of organisms and constructing phylogenetic trees based on shared traits such as physical traits, DNA and geographic location.

2. Write down the steps you followed to make your phylogenetic trees in 3-5 complete sentences. If you are short on time, I would select the link on the right. If you have more time, I'd prefer the Nova Evolution Lab. Please also indicate why DNA is a good source of information about relatedness of organisms.

ASSIGNMENT:

1. Go the the link above to complete a virtual lab on the fossil record.

2. To complete the lab, follow the set of steps on the left side of the lab screen.

3. Then watch the video on fossils.

4. Write 4-6 complete sentences about what you can learn from the fossil record. Include relative v. absolute dating in your discussion, as well as stasis vs. abrupt appearance of new fossils.

ASSIGNMENT: (preAP only, you must use the Phylogeny module, the rest are for exploration if time permits)

1. Complete the virtual lab looking at evidences that support the evolution of lizards.

2. Then, write 4-6 sentences summarizing the methods you used in the different modules to classify the lizards and determine their relatedness.

ASSIGNMENT:

1. Watch the video on the RNA origin of life.

2. Write 4-6 sentences about the origin of DNA. (Origin means where it came from) You may do outside research to help with the process.
