Seasonality of Seawater Chemistry

Using M1 and M2 mooring data, ready-made graphs for interpretation: density, salinity, temperature, etc.  Why are they like are they related?  Compare M1 and M2.

Problems: the graphs are difficult to print as is...need to be formatted for user-friendly printing! Temperature scale on coordinated graphs is different...makes comparisons difficult.

Can be used as a wrap-up after a unit on temp/sal/dens unit, uses analytical approach.

Extensions: revisit web site throughout year to track changes and make comparisons, couple with upwelling and light data to find relationships, compare with wind data to determine effects.

Primary Productivity

Compare upwelling and temperature data using satellite and observatory information.

Determine how abiotic factors affect biotic.

There is lots of data and it's hard to sort through, need to be able to find what is needed for the activity from a variey of different sources.

Compare 2 areas in the same region and determine what the differences are (wind, currents, etc.)

Students develop hypothesis and explore data to come up with an explanation, graph and compare dta and confirm findings.

Earth Observatory site is a useful tool for this activity.

Storms or other episodic events can spark student interest to revisit and compare data.

Building an Observatory

Develop stand alone lesson or doorway to other inquiry lessons? (Initial problem)

All scientific disciplines are interconnected.

Science and Technology should be shared but often aren't; S&T are pursued for different reasons. "Need to Know" driven.

Started with questions, a way to "hook" students.  How can we tie all the different S&T pieces into one lesson?

Virtual observatory?  Build an observatory that hooks into existing data to 'collect' data.  (ex. AOSN modelling component).

Build an aquarium:given guidelines but no instructions, must use data from the Web to determine parameters.
