Wednes-Day 2
Bio- we can begin Regents Review starting tomorrow! I'll hand out our schedule in class tomorrow but, if you would like to come to extra help tomorrow morning, I'll focus on Section 7: Evolution in our red/Glencoe review book; I will try to cover the questions from page 103 to page 110. You may want to preview that section so that we can immediately cover the questions that are more difficult for you.
We did a worksheet on the Carbon Cycle (see Blackboard); we'll get to the Nitrogen Cycle worksheet tomorrow. We saw that the TWO major sources of CO2 on Earth are the atmospheric carbon dioxide and also the dissolved carbon dioxide in the oceans. The CO2 balance is maintained via the "opposite" processes of respiration (produces CO2) and photosynthesis (consumes CO2).
We then discussed ECOLOGICAL SUCCESSION which shows the various stages of development of an ecological community of plants from simple grasses to, over time, shrubs and eventually to a final, stable CLIMAX COMMMUNITY of trees. The types of plants in a climax community depends on the level and types of abiotic factors and climate of its ecosystem.
Chem 7/8- we prepped/reviewed for tomorrow's Acids/Bases/Salts exam. The rest of the problems, including an extra question on indicators is posted on Blackboard. Later, I should have the annotated review packet posted.
We finished discussing the salt hydrolysis lab.
Chem 9- we prepped/reviewed for tomorrow's Acids/Bases/Salts exam. The rest of the problems, including an extra question on indicators is posted on Blackboard. Later, I should have the annotated review packet posted.
