Before Watson and Crick

Read the article, "Before Watson and Crick."

Answer the following questions. Use complete sentences, and restate the questions
  1. What type of physics research was advanced by WWII?
  2. What type of biological research was slowed down by WWII?
  3. How many years passed between Mendel's research and the discovery of chromosomes?
  4. What is an important chemical difference between DNA and RNA?
  5. Why did scientists quickly rule out RNA as the primary heredity material?
  6. Why did scientists initially suspect protein was more likely than DNA to be the primary hereditary material?
  7. What was Astbury's contribution to the study of DNA?
  8. Where did Avery eventually publish his research findings?
  9. Why did Schrödinger believe it was important to combine physics, chemistry, and biology?
  10. What was Schrödinger's series of lectures compared to?
  11. Where did Franklin do her DNA research?
Lastly, create a timeline for the events discussed in this article.

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.

meiosis homework

Watch the Bozeman Science video about mitosis and meiosis, and then answer the questions listed below. Write your answers on a paper and bring it to the next class meeting.


Here's the video


Here are the questions:

1. What is the centromere?
2. What do the beads represent in this simulation?
3. What's the goal in mitosis?
4. What two things does a cell do before it divides?
5. What happens during prophase 1 that leads to variability?
6. Why is independent assortment important?
7. What is "a little bit different" about egg formation during meiosis?

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.
