Lesson 3: Graphic Organizer
Introduction
In this lesson you will read pre-selected articles and compile what you learn into a digital graphic organizer. The goal is to relate what you have learned thus far to genetic variation. You may work on this project with a partner, but each person must submit their own original work. Groups of three or more need to be cleared by me. Refer to the "Student Resources" page of my teacher site for examples of graphic organizers. You organizer, however, will not be on paper but rather in digital form. Poplet is a popular online application you can use for your organizer. Many other online tools are also available. |
Content Standard and Learning Objective
California content standard:
HS-LS3-2. Make and defend a claim based on evidence that inheritable genetic variations may result from: (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.
Learning objective:
Cite evidence that genetic variation results from various processes including cellular division, DNA replication, and environmental factors.

Lesson Sequence
1. Review what you already know about meiosis and relate it to genetic variability:
2. Review what you already know about mutations and relate it to genetic variability:
3. Study a resource on variable errors during replication:
4. Study resources on environmental factors:
5. Learn about classic experiments that provide evidence for meiosis, replication, and environmental factors as sources of genetic variability:

Make Your Graphic Organizer
You have now learned about three major contributors to genetic variability: (1) replication errors, (2) environmental factors, and (3) meiosis. You have also learned about experiments that demonstrate these three mechanisms. Now put all this information together in a graphic organizer in a way that helps you visualize and remember what you have read. You may use Popplet or another online tool and you may work with a partner on this assignment, but each student needs to submit his/her own work.
Before beginning work on your assignment, go to this Stormboard link (ID = 98089, Key = world266) and make one comment in each of the three categories. Review others' comments for ideas of what to include in your organizer. If only a few people have made posts, make your contribution and check the board at a later time.
Your organizer must contain the following information:

Your organizer must contain the following information:
- The three categories mentioned above
- At least two pieces of evidence (from what you already know and from what you learned in this lesson) for how each of the three can lead to genetic variability.
- At least three examples or causes for each category.
- A total of at least three ways that scientists, breeders, geneticists, doctors, etc. have applied this knowledge to real-life issues.
- At least 5 images/pictures/graphics that will help you visualize and remember what you have learned.
Here is a completed example of the graphic organizer. This one was made using LucidChart, but you can use any software you choose. The grading criteria for the assignment and a timeline for its completion are listed in the following document for your reference.

After completing the assignment, refer to the content standard and learning objective above and see if you can meet them both.
