unit 3

The class textbooks had to be turned in for inventory, so you don't need to worry about the textbook assignments for unit 3. You just need to study the learning standards and be ready to pass the test. To help you all out with the limited amount of time left in the year, I have made a written test for unit 3, as well. So, if you haven't taken the unit 3 oral test already, you can take a written test on whatever day is your period's last day of biology. And whatever grade you earn on that multiple-choice and matching test will be entered into the gradebook.

Some of the information for the unit can still be read from the two chapters of the textbook, chapters 33 and 34 available online. But you can also find lots of great info just by searching Google or YouTube for the standards and vocabulary.

So, what you need to know can be found on the Unit 3 handout, which is available at this link.

Alternative 2.12-2.14 assignments

If you have not yet started assignments 2.12, 2.13, and 2.14, you can choose to watch those videos or to instead complete some book work. The videos are what I had planned, and you may still use those for the class, but since we will no longer have the laptops in class, I am making book-work available for those who cannot watch the videos.

When you take the unit test, I will ask questions based on whichever assignments you completed for the unit.

Here are the alternative assignments:
2.12 -- Read pages 510-528, and answer questions #1-2 on p. 515, #1-3 on p. 522, and #1-3 on p. 528. Here's a link to the chapter PDF.
2.13 -- Read pages 538-552 , and answer questions #1-4 on page 544, and #1-4 on page 552
2.14 -- Read the article, "Less jaw, big brain: Evolution milestone laid to gene flaw" from the NYTimes. Write a summary explanation of how a gene flaw helped lead to human evolution. Then read the article, "How language may have evolved to help our ancestors make tools," from Science. Write a summary of the evidence connecting language development and tool-making.

Becoming Human videos

Here are some ideas on what you need to know from the Becoming Human videos.

Episode 1
Where is Afar? Why is it important?
Who was Selam? Why is Selam important?
What is important about Selam's teeth, skull, spine, shoulder blades, feet, kneecaps, and tibia?

Poster design extra credit

Here's the extra credit opportunity for the 3rd 9-weeks.

You can design an educational poster. The poster is worth up to 30 assignment points. Plus, within each category and topic I will select a 1st place winner to receive an additional 20 test points.

There will be two categories for posters: 1) mixed media, and 2) traditional poster
The traditional poster category will include posters with only 2-dimensional graphics. The mixed media category can include 3-dimensional art and other techniques beyond colors and pictures.

For the topic, you can choose any one of the following:
scientific thinking/scientific method (ch 1)
biochemistry (ch 2)
the biosphere (ch 3)
ecosystems and communities (ch 4)
populations (ch 5)
humans in the biosphere (ch 6)
cells (ch 7)
photosynthesis (ch 8)
cell division (ch 10)
heredity (ch 11)
DNA (ch 12)

There are 11 topics multiplies by 2 categories, so there could be 22 1st-place winners. You can enter up to three posters.

Do not simply steal a design off the internet. If you are found to have stolen a design from someone else, you will receive no points.

Put your name and the topic on the back of each poster. The posters are due by April 1.

2nd 9-weeks grade recovery


This post explains the requirements for the grade recovery process. If you would like to improve your 3rd 9-weeks grade to the next letter grade, here's your opportunity. There are three parts to the process: 1) the textbook, 2) the videos, and 3) the test.

Part 1: The textbook

Read chapters 4-6 and answer the questions listed below. You must bring this work to turn in when you're ready for part 3.

Chapter 4: Ecosystems and Communities
Page 127 #1-10


Chapter 5: Populations
Page 151 #1-10


Chapter 6: Humans in the Biosphere
Page 185 #1-10

Part 2: The videos

Watch each of the 8 videos embedded below, and take notes on the videos. You will need to turn in the notes, along with the work for part 1, when you come in to take the test.


Ecology: Rules for Living on Earth

Population Ecology: The Texas Mosquito Mystery

Human Population Growth

Ecological Succession: Change is Good

Human Impacts on the Environment

Food Webs and Energy Pyramids

Ecological Succession: Nature's Great Grit

Biomagnification and the Infamous DDT



Part 3: The test

Once you have completed parts 1 and 2, you can take the final test. The test will be 45 multiple-choice questions, and you must score a 70% or better on the test to earn the higher grade. The test will NOT be open-book, so you need to know the material pretty well. If you do not score a 70% the first time you take the test, you may try it one more time. You must schedule a time with me to take the test.

All three parts of the grade recovery process must be completed by April 6, which is the last day of the 3rd 9-weeks.
