We are beginning Chapter 12 by starting a study guide, as well as using the microscopes to view stages of mitosis. The book chapter guide will also be handed out (as well as the objectives for Chapter 12). Both handouts should be finished by the beginning of class Wednesday.

Friday, November 20th In class and Homework

Today was a review day - preparing for next weeks test (Mon and Tues) covering the material from Chapters 8, 9 and 10. We went over any questions regarding the formative assessment for chapter 10, as well as any questions connected to the objectives for each chapter. The multiple choice segment of the test will be Monday and the extended response section will be Tuesday.

Thursday, November 19th In class and Homework

We worked on a large concept map today - encompassing terms from Chapters 8, 9 and 10- in order to help prepare for next week's test. A key was given out at the end of the period. The homework is to finish the map and to take the chapter 10 formative assessment that was also handed out at the end of the period. Test on Chapters 8, 9 and 10 will be Monday and Tuesday.

Wednesday 11/18/09 - In Class and Homework

We began the period reviewing photorespiration and fielding questions about the C4 and CAM adaptations. We spent the remainder of the period taking a chapter 10 formative assessment to be finished for homework. The chapters 8-10 Test will be Monday and Tuesday.

Tuesday, November 17th - in class and Homework

We completed a pigment chromatography "mini-lab" using a spinach (or begonia) leaf and a solvent to isolate the different photosynthetic pigments in order to determine their Rf values. We also started to look more closely at photorespiration, as well as some particular adaptations plants which live in arid climates have developed to minimize this. The homework is to continue to learn and write about these adaptations (C4 and CAM mechanisms). The test for chapters 8-10 will be Monday and Tuesday

Monday 11/16/09 - In Class and Homework

First of all, the respiration labs were collected. We used the computers in class today to visit 3-4 web sites dealing with the Calvin (light independent) cycle. We had some guiding statements to help us determine the depth to which we are required to learn this process (this helped with our note taking). The homework is to complete this. The test covering chapters 8 - 10 will be next Monday and Tuesday.

Friday, November 13th In class and Homework

We spent the period going over our 10.1 and 10.2 study guide, paying particular attention to the specifics of the light reaction (how ATP and NADPH is generated). We finished the period by asking/answering questions related to the respiration Lab. Our homework is to complete the lab to be turned in Monday.

Thursday, November 12th In class and Homework

A table showing an average result for our respiration lab for each of the variables (standard condition, acidic, basic, cold (4° C) and nongerminating) was passed out to the students. The students graphed the data, and determined the slope for each line. In addition, 8 analysis questions were included, and the students worked on these. This lab will be due Monday. The homework is to read 10.3.

Wednesday, November 11th - In class and Homework

We turned in our data collected yesterday from the respiration lab (in order for the instructor to compute averages and provide meaningful data to the students tomorrow. We then briefly discussed the difference between a table and a graph, as well as describing what "control conditions" mean in an experimental set up. Chapter 10 objectives were then passed out, as well as a study guide for Sections 10.1 and 10.2. This was worked on the remainder of the period and should be completed for homework

Tuesday, November 10th - in class and Homework

We gathered data for our respiration lab today. We used the lab quests and gas (primarily CO2) sensors to measure the rate of respiration of the wheat seeds we prepared yesterday, both under controlled conditions (room temp, neutral pH) and with one change (in pH and temp). We recorded the slope and set up a table and graph to make comparisons. The homework is to review sections 10.1 and 10.2.

Monday 11/9/09 - In Class and Homework

We began a respiration lab using wheat seeds - in order to investigate the relationship between respiration rates and germination, as well as temperature and pH. Each group of 3 set up a control condition (10 g of wheat seeds, 25 + ml of water, neutral pH and room temp), and chose one variable to investigate. We will collect the data tomorrow. The homework is to finish the 3 "day 1" lab questions, as well as read sections 10.1 and 10.2.

Friday, November 6th In class and Homework

We conducted a respiration candy "lab" tracing the transfer of energy from glucose (1/2 hershey bar) through glycolysis, the citric acid cycle and the ETC - producing NADH and FADH2 (gum drops with marshmallows ) - and finally the conversion to ATP (m & M's). The homework was to review Chapter 9.

Thursday, November 5th In class and Homework

We viewed part 5 of the respiration series of videos - oxidative phosphorylation - and then we completed the powerpoint for chapter 9. During this, we went over 2 animations showing the electron transport chain and how the majority of energy for this process is converted into ATP. We also went over the process of fermentation (anaerobic respiration). The homework is to review the remainder of chapter 9 and to take the chapter 9 formative assessment (handed out in class). Check how you did by checking the correct answers posted above.

Wednesday, November 4th - In class and Homework

We viewed part 4 of the respiration series of videos - dealing with the Citric Acid (Krebs) cycle. We then went through the 1st two thirds of a Chapter 9 power point, focusing specifically on Glycolysis and the Citric Acid cycle (Tomorrow is Oxidative phosphorylation). The homework is to review section 9.4 in the textbook.

Tuesday, November 3rd In class and Homework

(Substitute teacher day) We began the period by reading pgs 174 - 177. We spent the remainder of the period on the computer, checking animations of the citric acid cycle and the electron transport chain and describing these processes. The homework was to complete this if necessary
