Hi All,
Thanks for the Chromosomes and DNA short presentations today - please see the year through to the end. Too many people did not complete this assignment.
I will have your lab reports graded to hand back in the morning, along with a one-page DNA and chromosomes paper. You may want to use these to complete your self-assessment.
YOUR SELF-ASSESSMENT IS DUE FRIDAY, MAY 29TH.

Lab Reports Completed - now onto Cells
Hi All,
Lab reports were due Tuesday, and most of you have completed them. Thanks for all of your efforts to draft and refine your work!
Yesterday, you were to complete the prompt related to the plant and animal cells handout. The prompt: In our notebook, please identify differences between plant and animal cells.
Next week, we will look at plant and animal cells under a microscope, focus on the organelles of animal cells, and zoom in on the chromosomes and DNA.

Lab Report Dates
Today, your Conclusion is due.
I will be handing back your Hypothesis, Experiment Methodology, Performing the Experiment, and Data Analysis sections.
Your completed lab report, including Introduction is due on Tuesday, May 12th.
Please see the previous blog entry if you are in need of more site details for your Performing the Experiment section.

Site Descriptions for Lab Report
Strawberry Canyon (wild)
This site is in the upper part of the watershed, just below the University of California Botanical Garden. This stretch of Strawberry Creek is in a narrow forested valley without development upstream. There is a narrow, rocky creek bed, and the banks range from about 10 feet to 30 feet in height. An unpaved recreation trail runs alongside the creek. This trail is primarily used for runners, walkers, and dog walkers (lots of canine evidence left behind).
Strawberry Creek Park (urban)
This is a short daylighted stretch of Strawberry Creek, which extends for about 150 yards before again flowing under the city. The creek bed is mostly shaded, and consists of smashed pieces of the culvert that formerly contained the creek in this area. This area of Berkeley is urban with a mix of residences, businesses, streets, sidewalks, and the park, which does provide some protection for the water. After leaving the park, the creek again goes underground, and doesn't surface again it exits the culvert into San Francisco Bay at the bottom of the watershed.
Where Strawberry Creek Meets the Bay (industrial)
The last stretch of the creek is underground as it passes through the industrial area with warehouses, manufacturers, railroad tracks, the freeway, and traffic congestion. This bottom area of the watershed - where the Amtrak station and Truitt&White are now located - was the site of a large Huichin (Ohlone) shellmound. This mound was built over the 3,700 years that these people inhabited Strawberry Creek before European settlers took over the area. The actual spot where the creek hits the Bay can only be sampled when the tide is low. Otherwise, the tidal influence mixes salt water in with the creek's freshwater, and results are not accurate.

Lots of things coming up...
Hey All,
We are off to Mendocino County for our field work tomorrow.
Please do not forget that the next two sections of your lab reports (including the edited previous sections) are due next Tuesday, May 5. So, you will have your edited hypothesis and experiment methodology AND the first drafts of your Performing the Experiment and Data Analysis sections. Don't forget to have a nice, well-labeled graph that your data analysis text refers to.

As we continue with water.....
Hi All,
As we continue our water studies, I will be getting you a complete data set to begin working with next Tuesday. While you await that, I want you to begin viewing a very interesting film that is the starting point for our next unit on cells and DNA - The Journey of Man. Please complete the following work for Thursday's class.
At the halfway point of The Journey of Man, I hope that you are enjoying the scientific and cultural intensity of this film. Spencer Wells sums up the common difficulty of bridging science and culture when he asks, "What do you do when everything you believe in flies in the face of everything you know?" As a good scientist, he sets out with a set of hypotheses to gather data and test those hypotheses. Please answer the following two questions in your science notebooks for Thursday, March 26th:
1. For you, what was the most profound or useful scientific information or phenomenon addressed in the film so far? How and why did it affect you?
2. What was the most interesting or profound cultural element addressed in the film so far ? How and why did it affect you?
