Today I substituted for Carson's science class (my student Matthew was absent). There were no sub plans left so Carson helped me clean up from Black History Month. Then, we gathered the supplies he would need to finish up his art piece for the show on Thursday.
Define and discuss global change, global climate change, global warming, and the greenhouse effect.
Use examples to demonstrate the physical, chemical and biological changes which are part of global change. Discuss that global climate change involves changes in the weather over a period of time, and that these changes can be natural or anthropogenic.
Explain that global warming refers to a specific aspect of global climate change.
Outline and discuss in detail the 12 steps which create the greenhouse effect.

Lesson Comments
Joshua was right on target answering the free response questions today
Discuss the specific effects of pesticides and plastics on hormone responses. Concentrate on hormones present during gestation, and on the effect of hormone mimicking chemicals on the development of the fetus
Complete the reading of the paper presented by ABC news which deals with the complex issue of Arctic heating. The long range effects it will have on the economy, shipping, plant and animal life which cannot adapt, and military preparation.
Continuation the discussion on the ABC report which describes the Arctic ice sheet melting, the polar ice caps, and the permafrost. This unit today concentrates on the world wide effect the melting ice caps has on ocean rise, jet stream fluctuations and movement of cold air into regions not prepared.

Lesson Comments
Unfortunately, the desk top computer in the science lab was occupied, both lap tops available in the cabinet could not access teams. Eventually, a desk top in the library was successful, but the ambient noise made it near impossible.
Continue discussion presented by ABC news regarding melting Arctic ice. Review of arctic amplification theory regarding the greater rise in temperature in the Arctic region than elsewhere.
Diagram to show that the Sun's rays are not reflected as much as previous. The exposed land and water absorb more of the energy, which was previously reflected.
The biggest long-term effect of warming in the Arctic will be sea level rise. The level has risen 6 inches since the industrial revolution.
The loss from the Greenland ice sheet will have its greatest impact on places far away from the Arctic. Sea level rises from melting and continued climate change will exacerbate coastal erosion.

Lesson Comments
Ayden diagramed the melting and sea level rise quite accurately.
Read the initial part of a paper presented by Julia Jacobs based on a discussion on ABC News by meteorologist Ginger Zee.
The report discusses how melting ice will have catastrophic effects on the world.
Read and discuss why the ice melting allows for a greater warming due to loss of reflection and increase in dark water absorption of heat energy.

Lesson Comments
Due to a misunderstanding regarding Aydens' earlier classes, he was not on line until 10:30.
Complete viewing the lecture dealing with the measurement of temperature change, greenhouse gases concentration changes over thousands of years, and the charted relationship between the concentration increases and the melting ice caps and ice glaciers.
Discussion of new methods of measurements and the use of drones to photograph the shrinking ice caps-
