Do work pages 9-12 due on Thursday
PowerPoint Presentations on Thursday (Breige and Evie went today and they were very good!)
Basil Seed growing - bring a half page write up on what you have observed or done.

Portfolio, New Bio Color Pages on the Environment - 15 minutes
Bill Nye Labs on Chemistry DVD - 15 minutes

Chemistry Experiment Lab - 50 minutes
- Tools of the Lab
- Experiment 1 with Water
- Experiment 2 with Vinegar
- Reflection on what transpired
Vinegar is composed of about 5% acetic acid. This is the major chemical component of vinegar.
The systematic or proper chemical name of acetic acid is ethanoic acid.
Vinegar is a weak acid produced by the oxidation of alcohol (ethanol) from wines and ciders by bacteria. It has a pleasant sour taste and is used in cooking or as a condiment. It is commercially sold as white vinegar, brown vinegar, cider vinegar and balsamic vinegar.
The complete structural formula of acetic acid is as follows.

The condensed structural formula for acetic acid (the main component in vinegar) is CH3COOH.This formula is a shorthand way of representing the complete structural formula (see above picture).The first carbon atom is surrounded by three hydrogen atoms. The second carbon atom is surrounded by one oxygen atom and a OH group. Hence it's formula is CH3COOHThe molecular mass or molar mass of acetic acid is 60.05 g/mol
The Experiment today:
Question: What do vinegar and baking soda mixed together yield? What is the balanced equation of this reaction?

Replies: Vinegar is acetic acid: CH3COOH
Baking soda is sodium bicarbonate: NaHCO3
Mixing the two is simply and acid base reaction.
CH3COOH + NaHCO3 ---> CH3COONa + H2CO3
That last product is carbonic acid which quickly decomposes into carbon dioxide and water:
H2CO3 ---> H2O + CO2
The CO2 is what you see foaming and bubbling in this reaction.

Power Point Presentation on your research report are due next week (only 10 slides....easy).
Basil Seed assignment: Growing chamber 20 points, 10 points write up on what

Video notes on Blue Gold, Water Wars Documentary

Assignment collection and review of the syllabus
Bio color on the Carbon Cycle
Basil Seed Growing Chamber Demo of student who used a cereal box and aluminum foil.
Discussed the PowerPoint Presentation and James did a tutorial on how to make a powerpoint.
You can download an Open Office program called Impress that is like Microsoft PowerPoint by going to this link

Activity Pages Chapter 2 done in class on Chemistry, Video on Chemistry
continue to work on syllabus assignments.
Thursday James will do mini lesson on PowerPoint.

Seeds in Space Program from NASA click here
Your Seeds flew on Space Shuttle Mission STS 118!
You are to build a growing chamber for your basil seeds with simple recycling materials. Design and construct two chambers so you can plant seeds by next Tuesday. Keep a journal of what you do and what happens with your Space Seeds and the Regular Seeds. The seeds that went into space were exposed to full radiation from the sun. What will happen? Can you predict?

Biology Syllabus was handed out in class today and Due Dates were discussed. Date assigned and dates due are listed on the syllabus.

Biology Lab on Water and Polymer Beads - Environmental Entrepreneurialism!
Student wore Lab Coats, developed lab teams with roles. Conducted  Water Lab with Hydro Beads. Expansion of a Hydro Polymer with H2O.
Lab Notes, Lab Partner
Blue Gold Video Documentary - the story on water!

Student reading of Science Research Reports - Reading what other students wrote on is always interesting.
Seeds from Space! You have been given seeds that flew on STS- Space Shuttle Mission 118.
Please create a way to grow both packets at home and document what you do to design, build and observe the growth of these Basil Seeds that were flown 300 miles above earth surface and exposed to solar radiation. The documentation is a fun long term project and a connection to a select few groups that have access to these seeds.

Bio - Color on the Energy Pyramid, goes in portfolio

Nova Series - So Where Did We Come From? Tyson Neil DeGrasse

A revised schedule will come out on Thursday with handouts, worksheets and due dates.

Thanks, MR. Ewart

We reviewed individual student progress reports for Learning Period 1 and 2. There are 5 learning periods in a semester and = 5 units. Fall and Spring = 10 units. What do you need to graduate from H.S.???

What is due? see assignment packet
Watch Six Degrees of Separation. A National Geographic program on our connections on a global perspective in the area of Physics, Biology and Psychology.

Portfolio - Bio Color on the Water Cycle
Discussion on Lessons Due and Report's Due today or latest Thursday.
Read model reports and had discussion on Six Degrees of Separation, six degrees from Kevin Bacon.

► 47:14► 47:14

Six degrees of separation on Vimeo vimeo.comAug 16, 2010 - 47 min Documentary unfolding the science behind the idea of six degrees of separation.

We modeled this idea of human connectivity using post it notes for students and two other people they knew. We noticed patterns like a flower, honeycomb, ripples, Google Circles!!! Social Media...it was a profound class with lots of great input. I look forward to the rest of the reports on Thursday.
