Today's schedule is BADC
B Block Human Geography - Today we are back in the learning commons/library for our second day to work on your endangered language poster. Don't forget, your job will be to create an information graphic poster on an endangered language. For your endangered language you’ll need to:
- Show where the endangered language originated and diffused to (yes on a map).
- Show the connection to the family, branch, and group of the endangered language. (Use your best judgment on this).
- Show where the language is spoken today, indicate how many people speak it.
- Show Unique features of this endangered language (What makes it different to and similar than others?)
- Show examples of how the language is written and or spoken
- Show why your endangered language is important to save
- Show how your endangered language is both being threatened (contributing factors) and being saved
- Show how people can find more info (links...sources cited)
A Block Physical Geography - Today we look at stream profiles, deltas, and floodplains. We are focusing on the erosive action of rivers along with the land forms that they create. You will need to copy a meandering stream profile (figure 14.15 on p.460 in the Geosystems text) and a diagram on oxbow lake formation (figure 14.16 on p.461 in the Geosystems text). Your homework is questions 17, 20, 21 & 22 from page 482 in your Geosystems text.

D & C Blocks Environmental and Social Sciences - In D Block with Benton you'll be looking at global images where we will compare the Oceans considering the variety of factors, comparing and contrasting Arctic, Temperate and Tropical. Ocean Primary Productivity will be a lens through which to analyse these variations and compare energy and ecological systems. Next we'll be in the Super Lab doing an examination of multi-cellular algae, (seaweed), samples in salt water through drawing key features and identifying. The extension will be to the depth ranges and habitats of primary producers in the ocean.
Chlorophyll A (predominant plant pigment) - absorbes blue 430nm and red at 662nm, saltwater absorption to blue wavlengths.

Arctic – low angle, algae growth > 45m
In C Block with Young we begin our look at wind driven ocean circulation, geostrophic flow, and gyres. This connects us to the tragedy of the commons and the great pacific garbage patch which we'll look at tomorrow. So today...Wind, tides, and differences in temperature and salinity drive ocean currents. The ocean churns up different types of currents, such as eddies, whirlpools, or deep ocean currents. Larger, sustained currents—the Gulf Stream, for example—go by proper names. Taken together, these larger and more permanent currents make up the systems of currents known as gyres.
A gyre is another name for a swirling vortex. Ocean gyres are large swirling bodies of water that are often on the scale of a whole ocean basin or 1000’s of kilometers across (hundreds to thousands of miles across). Ocean gyres dominate the open ocean and represent the long-term average pattern of ocean surface currents.
Our activity today will be "Predicting the Patterns and Characteristics of Surface Ocean Currents" from the American Meteorological Maury Project.
