Journey of Man Part 1 and Living Cells

Hi All,

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 Monday, January 28th:
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?

Finally, also for Monday, 1/28, please freewrite in as much detail as you can in response to this prompt:
What are living cells?

Last Gasp for Extra Credit

Hey All,

One last chance for extra credit:

In the previous post, I gave the details for the reflection on Sylvia and David's talk on 1/10. Please follow those guidelines, and have your reflection to me by the end of school this Friday, 1/25. The talk is about 1 hour and 20 minutes long, and it is on all six of the computers in the main room in the Save the Bay folder on the desktop. The file is nearly 1 GB in size, so a high capacity flash drive will be needed to take it home with you (feel free to do so). Please be detailed in your reflections.

Reflection on Sylvia McLaughlin and David Lewis

Please respond to the following prompt in a DETAILED PARAGRAPH (1 point):
What are three things that you heard in Sylvia or David's presentations or answers that surprised or impressed you? and why did this information affect you?

Prompt #2 (.5 points):
Based on the information, what is one SIGNIFICANT thing that you can do to protect the Bay? Explain why this action has a significant effect.

Extra Credit anyone?

Hey All,

After so much hard work this past month, I hope that you all have a joyful and restful break.

EXTRA CREDIT BONANZA! In case you get restless, go through homework withdrawal, or just want to explore a few new and expanded avenues of our environmental studies, below are a few extra credit opportunities. They will all count individually, so you can do as many of them as you wish.

Sustainability Game
The half sheet of paper handed out in class is the worksheet to go with this game that challenges you to balance resource extraction with making money. PLEASE EMAIL ME IF YOU DIDN"T GET ONE. Good efforts, reflections, and insights will boost your final semester grade by one point. Go to www.sustainabilityed.org.

Add to the Planetfesto Ribbon
Check out www.planetfesto.org. This is a website created by a couple of current BMS parents to enable people around the world to express their appreciation and stewardship of the planet on which we live. Customize your images and text, and show us all when we get back in the New Year. Creativity and thoughtfulness will result in up to two extra points on your final semester grade.

Dialoguing with Sylvia McLaughlin
We have a very special event on the evening of Thursday, January 10th, and we need various forms of help:

1. Are there students who would like to represent the MS in discussion with Sylvia? This would include compiling the questions that we posed back in September when we read her “Saving the bay, again” piece from the SF Chronicle. There were many thoughtful questions that will really spark some excellent discussions and insights! Three extra points on your final grade for this.
2. Compiling photos of the scientific and artwork that we did in the Strawberry Creek Watershed. It will be great to display the watershed studies that we have been engaged in over the last couple of months. Two extra points on your final grade for helping with this.
3. Helping at the event with tickets, seating, refreshments, etc. One extra point on your final grade for helping with this.
We should have a big presence at this event to show our engagement in the Strawberry Creek and larger SF Bay Watershed.

On a more mandatory note, if you received a missing work slip, please have it signed for Monday, January 7th, and complete all of the work by Friday, January 11th. If there are worksheets you need, or questions that you have, please email me at shurd@bmsonline.org.

Have a wonderful break, and see you in ’08.

Genographic Project Update

Thank you to the 14 students who brought in their forms to participate in the drawing to have DNA extracted, analyzed, and shared with the class. The three students chosen were: Aaron, Nojan, and Ana. Sampling will happen early this week so that we will hopefully have the results by the end of January. I have been learning more about this project, and it is extremely cool!

Moving Ahead with the Lab Report

Hi Everyone,

I hope that you are all working away with the data relevant to your hypotheses and experiments.
To stay on track with this assignment, you should have the first drafts of the Performing the Experiment (Experiment Explanation) and Data Analysis completed on Monday. If you are falling behind, please check in with me on Monday.

As part of the Performing the Experiment section (Experiment Explanation), It was mentioned that you should describe the sites at which the data were collected that you are using. The following are some brief descriptions of the sites. Please feel free to use these descriptions if they help - also add your own observations if you were at the site.

Strawberry Canyon
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).

University of California
After leaving Strawberry Canyon, Strawberry Creek flows underground in a culvert before resurfacing on Cal's campus. On campus, the main branch flows primarily through shaded areas. Near the western edge of campus, in a grove of massive eucalyptus trees, this main branch of Strawberry Creek merges with the smaller north branch, which surfaces as it exits a culvert near the north gate of campus. This north branch runs through more developed areas upstream. On campus, the north branch runs through redwoods and the lawn area near the science building before entering the eucalyptus grove. Below the confluence of the two streams, the creek flows in an exposed shaded creek bed until leaving campus and flowing underground through a culvert. It resurfaces in Strawberry Creek Park.

Strawberry Creek Park
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
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.

National Geographic Genographic Project

Hey Everyone,

Following up on the email that I sent the other day, permission slips for students to participate in the drawing to be one of three students contributing DNA to the Genographic Project are now available. THEY MUST BE RETURNED BY FRIDAY, DECEMBER 14, which is when the drawing will occur.
