Friday 9.16 Today I collected the Review Sheet that was h.w. last night and we took the Unit One Test. If you were absent, you will need to make that up in the Testing Center when you get back. There is no h.w. over the weekend!
Thursday 9.15 Today I collected "The Effect of pH and Temperature on Enzyme Activity" graphs and Analysis Questions that you did last night for h.w. We went over the Liver Lab Analysis questions as a class (key below). Tonight you need to complete the Unit One Review Sheet (attached below) for h.w. I also have a couple of things you can complete in case you want some extra practice. Good luck studying! TEST TOMORROW!

Wednesday 9.14 Today I performed the two demos for the Liver Lab. The results are below:
Demonstration # 1 – Manganese Dioxide (MnO2), a inorganic compound, did react with the Hydrogen Peroxide.
Demonstration # 2 – I placed two pieces of liver in two different environments. Dilute HCl acid (pH = 2) There was no visible reaction when I added Hydrogen Peroxide to the liver in the acidic solution. Sodium Hydroxide (NaOH) (pH = 13) There was a moderate reaction when I added Hydrogen Peroxide to the liver in the basic solution.
For h.w. tonight you need to finish the Liver Lab Analysis Questions (1–9). They do NOT need to be typed. You also need to complete the Enzyme Lab Graphing Activity (attached below). You will be making two separate graphs; one on Temperature and one on pH. Each graph should have three lines. Make sure to include a key and all the other elements of a great graph. After you finish the graphs, make sure to answer the analysis questions! Our test over this unit is on Friday.
Tuesday 9.13 Today we did the Liver Lab in class. For h.w. you need to download my PowerPoint on Enzymes and fill in the guided notes below. I have copied my notes below just in case you can not open my PowerPoint. Plus, if you did not complete the Section 2.4 Review Questions on page 42 in the book (1–6) last night you need to do those as well. Our test over Unit One is this Friday 9.16.
They speed up chemical reactions that would otherwise take a long time
This is called catalyzing the reaction
How do enzymes get named?
Enzyme names usually end in -ase
The name usually includes the name of the substrate
The substrate is the substance that the enzyme works on.
Example) The enzyme that catalyzes the break down of lactose is called “lactase”
How do enzymes work?
They are only required in small amounts because they are not used up by the reaction
At the end, you will have as much enzyme as you started with
They work by the lock and key method
Are enzymes specific?
The shape of the enzyme perfectly fits the shape of its substrate
Like a lock and a key!
Therefore, enzymes will only work on one substrate
Monday 9.12 Today I collected the Radish Lab Write Up. We went over the Organic Compounds Chart and w.s. that you completed on Friday (keys attached below). We also went over the Textbook Section 2.3 Review Questions (key below). Then we discussed the Liver Lab that you will be completing in class tomorrow. For h.w. you need to complete the Liver Pre–Lab questions (1–8) and also read Textbook Section 2.4 and answer the Review Questions on page 42 in the book (1–6). Our test over Unit One will be this Friday 9.16.

If you were absent you will need to make that up in the Testing Center when you return. After the quiz we worked on the Chart attached below on the four Organic Compounds. Whatever you did not finish in class is h.w. You also need to work on the Radish Lab Write Up. The Radish Lab Write Up is Due on Monday 9.12. Good luck!
Wednesday 9.7 Today I checked the Section 2.2 Review Questions that were h.w. last night and we went over them as a class (key attached below). Then we took notes on Section 2.3 the Chemistry of Cells. Tonight you need to answer the Section 2.3 Review Questions. They must be typed.

Tuesday 9.6 Today was the last day to collect data for the Radish Lab. Groups calculated averages for the experimental and control groups and then cleaned up. The Radish Lab Write Up is due on Monday 9.12. Be sure to follow the proper format discussed in class (see the Lab Write Up handout attached on my homepage). Then we took notes on The Nature of Matter (PowerPoint and handout attached below). For h.w. you need to read section 2.2 in the textbook and take notes. You may use either the Cornell or the SQRRR method for your notes. You also need to answer the Section 2.2. Review Questions (#'s 1–5). These must be typed! Our quiz over the Scientific Method and The Characteristics of Life (Textbook sections 1.1 and 1.3) is this Thursday 9.8.
Friday 9.2 Today I checked the graphs from Experiment One and Two that was h.w. last night. Then groups met to collect data on our Radish Lab Experiment. You should have also added an additional 10 mL of liquid to each bag. Don't forget to add this step to your procedure. We went over the Section 1.1. Review from the book (key attached below). Tonight for h.w. you need to complete experiments 3 and 4 on the Analysis of Scientific Experiments w.s. You will need to make a data table for experiment 4. Remember to use a ruler!

Tonight for h.w. you need to complete experiments 1 and 2 on the Analysis of Scientific Experiments w.s. (attached below) You will need to make a graph for each experiment as well. Remember to use a ruler!
Today I collected the Section 1.3 Review Questions that were h.w. last night. We watched a video clip from the Graig Ferguson show. Dan Riskin, the Host of "Monsters Inside Me" was his guest and proposed setting up an experiment where 30 high school students are infected with a parasite! We watched the clip and then completed a w.s. (attached below). For the rest of class time, students met with their groups to collect data on the Radish Lab and to write a procedure. If your group did not finish this in class you should do that tonight for h.w. You also need to complete The effect of Coat Color on a Mouse's Heart Rate Data Table and Graph (w.s. attached below) and Investigating the Scientific Method w.s. (attached below).

We then set up the Radish Lab. For h.w. you need to take notes on section 1.3 in the book on the Scientific Process using the SQRRR method of taking notes. There is a pdf attached to my homepage that outlines the SQRRR method. Then, answer the section review questions (# 1–5) on page 20. These must be typed!
Monday 8.29
Today we had our first warm up activity. Everyone completed a quick w.s. to review the seven characteristics that all living organisms share (attached below). I checked to make sure everyone had a three ring binder for class. I also checked in the background research for the Radish Lab. You needed to research germination and growth of radish seeds and the effect your independent variable might have on those two factors. We also discussed the proper format for creating Data Tables. Your h.w. tonight is to make 2 data tables that you will use to record your data in this lab. You need one data table for germination and another for growth rate. You can reference the Lab Write Up handout I have attached on my home page. Be prepared to set up your experiment tomorrow in class!
Today I collected the Section 1.1. Review Questions and we took our first quiz over Lab Safety. If you were absent, you will need to make up the quiz in the Testing Center when you return.

We then got to know each other a little better by participating in a human scavenger hunt. Students had to walk around the classroom and find someone who shared a particular trait/activity/fact with them. Thank you having so much fun with this! I also get to know each of you a little better. Finally, we went over the Class Policies. You need to have a parent sign the bottom portion for h.w. and bring it back tomorrow. I have attached a copy of it below for you. Remember to purchase a 3 ring binder and index cards if you have not already done so. I will do a binder check on Monday, 8.29.

Welcome to Biology! Today was the Freshman mini–schedule, so we only had 10 minutes of class. We arranged ourselves alphabetically into seats without talking. Congratulations to my first period class who did it in one minute and fifty seconds! Very impressive! The only h.w. was to join my wikispace and to purchase a 3 ring binder that you will use JUST for Biology. I will do a binder check on Monday, 8.29, so you have until then to buy one. You will also need to purchase some index cards. You will not need those until the end of Unit One; in about three weeks. Please remember to bring your goggles to class tomorrow.
