Mrs. Stein started off the class by showing us an amazing demonstration of enzymes reacting to other substances. In this demonstration she had hydrogen peroxide, potassium iodine (our enzyme), and a huge cylinder. She poured only a little bit of the hydrogen peroxide in the cylinder and then she sped up the diffusion by adding potassium iodine and in a matter of one second, the hydrogen peroxide foamed like crazy and shot out of the cylinder. Of course, before this experiment, Mrs. Stein had put on her goggles and reminded everyone that they should be worn in the lab we we're about to do. This was a fun demonstration that got every ones attention the second the substance started foaming up. Now every single person was astonished and awake.

Then later on we started our Enzyme Lab and we were assigned to find out how the catalase reacted in our group’s different temperatures. In the lab we used hydrogen peroxide, sucrose solution, catalase, and water. We were to do three experiments in all, and in almost all of them, the substance started to bubble.

Then towards the end of class we were supposed to have experiments with the substances in our specific temperatures. We did as many experiments as we could until class was over.

Halfway There!

Our homework assignments for tonight are, pages 33-37 in our unit packets which are due tomorrow. We have to keep working on our lab write ups for the Rip-O-Meter lab, which must be TYPED. This assignment will be due on September 8th. If you are struggling with the write up, some useful tips are on pages 31 and 32. Also our first quiz in biology will be tomorrow so make sure you study! If you aren't sure what will be on the quiz, a good resource would be on the first page of our unit packet. Be sure to visit Mrs. Stein before September 4 for you homework pass.

Today in biology class after we were done with our daily routine, writing down the homework assignments and talking about the new blog post. We went straight into our Microscope lab that we had started yesterday. In class we mostly finished up looking at the different specimens, like the pond water, where everyone got to observe with their microscopes living things moving around. At the end of class we discussed more about the lab.

Also, don't forget to bring in your lab books and goggles to class this week! Which we will be needing for next week. And if you are looking for a club to join, Mrs. Steins leads the Cure club for cancer awareness, their next meeting is on Wednesday September 15 at 7:30 in the SAO.

Microscope Tuesdays!

Last night, the only homework we had was to work on our lab write-ups for the rip-o-meter lab. Mrs. Stein changed the due date from September 10th, to September 8th. The write up must be typed. If it is not typed then you will receive a zero for the assignment. If you need help the write up, there is a format page in our unit packet, pages 31 and 32. Other reminders that where on the board where: Our first quiz is Thursday the, 2nd. The unit packet, pages 33-37 are also due on Thursday. Don’t forget to visit Mrs. Stein for your homework pass!


Once we went over the reminders, we went over the homework. Mrs. Stein said that we must use our own words when doing our homework. The reason for this is that she wants us to prove to her that we are learning something from the lesson and not just copying what the book says.


When we where done with that, she assigned a new lab for when we where done with the rip-o-meter lab. The lab is to examine different materials under a compound microscope. The purpose of this lab is to become more familiar with this particular microscope. Mrs. Stein taught us how to properly hold it, which is always by the top handle. She also explained that when you first look at something through the microscope you start on the lowest power, which in this case is 4x. If you have any questions about the lab, pages 33-37 in our unit packet explain the lab.

Don’t forget to bring in your goggles and your workbook to class this week!

Monday,FUN-DAYY!!

Today in class we turned in our 6 questions for section 1.1. This was the homework assigned last Friday.


For tonight, our homework is to read the appendix on pages A-14 and A-15 and look at the virtual microscope. Also, a write up for the Rip-O-Meter lab that we are currently working on is due on September 10th. Pages 31 and 32 are good sources to help you get started with your lab write up.

During class we first finished up our pre lab questions and turned those in. After completing the pre lab, we then went on to start the Rip-O-Meter lab. My group decided that we were going to test out what would happen if we used different size leaves. We pierced our leaves at the point where all the veins came together because we agreed that would be the strongest part of the leaf. We also talked about making sure we place the pennies in slowly every time because the experiment wouldn't be controlled if we were throwing pennies in one trial and gently placing them in the next. Most groups just finished the testing part of the lab when class ended.

Also, bring in your lab books and goggles to class this week. We will be using the lab books in class next week.

First Friday of Bio!

Today in biology, we showed Mrs. Stein our homework, and got a second stamp for completion. After that, we went over the homework, which were Simpsons themed worksheets. During that, we reviewed what independent and dependent variables, and control groups are. Mrs. Stein told us a secret on how to remember what the independent and dependent variables were. She said that the independent variables were the data that you are trying to figure out, (independent, I am trying to figure out), and the dependent variables are the data that you’re collecting. (Dependent, Data). After that, we started a lab with leaves. We wrote our own hypotheses and questions to the lab. It was a great way to end the week in Bio.

2nd Day Over!-8/26/10

Today in class we got computers and we learned our username and password for our Glenbrook South account. We also learned how to get onto Moodle, a website where students can find the homework and projects due for their classes. Then we went on blogspot, to learn about how to post and comment on our period 3 class blog. Afterwards our class listened to the drug and alcohol policy and our class policies. Then to conclude our class, we watched three videos on cyberbullying and how important it is to make it stop. Overall today was a good introduction to our upcoming science year.

Scribe-8/25/2010

Today in class we learned that Moodle is a blog for your teachers and your classes. It is a very strategic resource to use. Also we learned what science is and gave some examples of it on the board. We also did a lab that involved milk, food coloring, toothpicks and soap. We put food coloring into the milk then added soap and watched some pretty cool things happen. It was a fun day overall and a good first day of Biology.
