Tie together the importance of the major factors in weather formation, latitude, temperature, wind, rainfall, and oceanic currents. A government video is specifically designed for this purpose. Discussion of the major factors as pointed out will follow the viewing.

Ayden was online today, but there was a problem initially contacting him. The desktop in the lab was unable to get on line with him, no internet connection. Moved to the library, where eventually a connection was made. After repeated attempts, Ayden was reached by e mail. Repeated attempts at reaching him on line were unsuccessful.
Discuss the effect of latitude on climate.
Using a map of air current circulation discuss the movement of cold and warm air and its affect on wind production and rainfall.
The affect of subtropical gyres and associated ocean currents is used to explain the redistribution of warm and cool masses of water and the affect on climate.
The El Nino pattern is discussed and how it causes warm water eastward.
Finally, how topography influences the climate. MT. Kilimanjaro is used, along with pictures, to explain how height shows the effect of climate on temperature.
List and briefly discuss the objectives of the chapter.
Using examples, discuss and list the factors which are involved in weather determination.
Use examples to differentiate between weather and climate.
Define weather as a short term phenomena which involves temperature, wind, rainfall, and humidity at a particular spot in a defined time.
Discuss climate as a long term atmospheric change. Use weather in Seattle and Phoenix on the same day as possibly being the same, but that climate in Seattle is cold, humid and rainy, while Phoenix climate is hot, dry

Lesson Comments
On line lesson- all notes were written on blank whiteboard and screen shot by Ayden
Continue reading and analyzing the chapter in Silent Spring which was begun on Wednesday. This chapter deals with aspects of the accumulation of toxins within cells and tissues, and the slow release of them into the blood stream over many years.
Read and discuss paragraphs from the chapter titled "The Human Price." This deals with the tide of chemicals born of the industrial age.
Discussion was centered around the environmental health problems which were prevalent at the time, and extrapolated into those which are most prevalent today.

Ayden was on line. Paragraphs were read and Ayden was very involved in the discussion
Tie together the unit just completed dealing with air pollution.
EPA video on the history of air pollution and the steps taken by the EPA to curb the effects.
How ozone is produced in the atmosphere, and the effects on the health of the population from ozone close to the ground.

Lesson Comments
Ayden was on line today. The only computer available at his class time was a desk top in the library.
Ice is placed in the bottom of a basin, and a glass watch glass placed on top of the ice. The temperature of the air in the room is determined and the air temperature just above the glass watch plate determined. A piece of string or rope is burned, the flame blown out and the smoking string placed on the glass. The smoke only rises until it hits the warmer air above the ice, then it stops. Normally, warmer air is closer to the surface than cooler air and the smoke would rise through it. This demonstrates now smog is produced in cities.

Lesson Comments
Different materials were burned, and the smoke rise noted.This was done outside, as some of the burning materials produced sulfur dioxide gas.
Discuss what category of humans are primarily affected by air pollution. In the elderly, death certificates are issued listing emphysema, heart disease, and lung cancer, but nothing listed as being linked to air pollution.
Discuss the short term and long term effects of air pollution.
Introduce both light and sound as pollutants, and use examples.
List the factors involved in "Sick Building Syndrome"

Lesson Comments
This was to be a lab investigating temperature inversions, but Ayden was on line.
Discuss how the industrial revolution has contributed to the increase in air pollution. Examine the fuels used and the waste gases produced.
Outline how a temperature inversion will lead to smog.
Prepare for a lab on Thursday which will examine smog and a temperature inversion

Lesson Comments
Ayden was stuck in traffic this morning, late be about 30 minutes. We did outline the lab to be done on Thursday
Discuss primary and secondary air pollution.
Define primary and elicit sources from Ayden.
Define secondary and also elicit sources of secondary pollution.
Outline the history of air pollution beginning with the Romans 2000 years ago through the outlawing of burning certain types of coal in London 800 years ago.
List the sources of most air pollution, with auto emissions being the number one source. Show how the burning of gasoline releases energy but the waste is converted to carbon dioxide, carbon monoxide and sulfur dioxide.
Initiate a discussion regarding how to cut down on the emissions.
Discuss why electric cars were the first ones, but were replaced by the internal combustion engine in the early 20th century.
Talk about the EPA, the Clean Air Act, and the use of catalytic converters to clean exhaust gases before they are emitted.
