Hello guys,

So to start things off we turned in the isopod lab that we worked on last week.

We then jumped right into the Starfish dissection lab. First dissection I have ever done that did not smell really bad so if you were not there, you missed out. Hah. Essentially, the idea of the lab was to open up and observe the parts of the starfish and to also improve our dissecting abilities. We even broke open the goggles drawer and popped those on so we knew right away that it was about to get real from there on. The lab was on page 63-66 and was pretty self-explanatory. It listed the parts of the starfish we would observe on the front page of the lab(63) and after reading the descriptions of each piece and their location, finding them was easy. For those of you not there today, I am assuming you will not be given another chance to dissect a starfish so I'll tell you what I got at the very least for each blank.

1. 5 rays

2. rough and hard

3. they have very rough skin

4. hard

5. it has 5 pyloric ceca

6. 5 gonad pairs

7. one

8a. ventral

8b. underneath it

9a. dorsal

9b. on top of it

10a. system for transporting blood

10b. blood

11a. its transportation system for moving water to move and get food as a result

11b. water

12. 5 radial canals

13. one circular canal

14. 5 tube feet

A tip for the first question is the phrase penta radial symmetry. I highly recommend looking this word up as my definition-something that can be divided into 5 sections each with the same internal and external structure-may not do the phrase justice or may not completely make sense to you.

Don't forget to do page 66 (its on the back of the lab)!!!

When we finished the lab we watched a movie about bugs for about ten minutes. To some it up in a sentence: Bugs are everywhere, they are some of the most successful organisms on the planet, and the ones on land are eerily similar to their ancestors in the water.

HW:

Finish the lab (63-66)

Sorry for the two posts. The site only allowed 5 pictures per post so I need to make two.

Monday 11-28-11

In class today we did notes for the new DNA packet on pages 1-10. We also watched a video about DNA crime solving techniques and how much more complex and complicated they are then the tv shows make them appear to be.

The HW for the night was as follows:

1. Read CH 10 p. 171-187

2. TEST on Monday 12/5

3. bring colored pencils / pens

DO NOT do the tribune activity!!

October 19, 2011

Today, we set up our Bacteria Labs in class so that they would ready for us to observe the following day. We split up into groups of two. One of the partners set up "How common are bacteria and how quickly do they reproduce"

They needed to follow the directions on pg 19-20 in UP to do this which included

labeling their dish into 4 separate areas

then using 3 different items to wipe on top of the different areas, one in each, with no object wiped in the fourth section as that is the control

make sure to label which items were wiped in each section

close your petri dish now and give it to your teacher

The other partner followed the procedure on pages 23-24 for Lab "Using Antibiotics to stop bacterial growth"

follow these steps:

label your dish into 4 separate areas

take a cotton swab, dip it in bacteria broth, and then wipe it all of the the petri dish nutrient agar so that each section has the same amount

take three different antibiotics, using the tweezers, and place them in separate sections

take a plain piece of paper and put it in the fourth section as your control

make sure you label which antibiotic is in each section

close your petri dish now and give it to your teacher

We also took an extensive amount of notes, all of which can be found through the Gbs Moodle page if you go to the Bio Metacourse and click on notes for UNIT 3. For an odd reason, my link is not working however so I hope that I am just unlucky and that you will all have no trouble with the link loading. The pages we covered in the notes packet were 1-12.

HW:

Read "Just an Upset Stomache" pg 27-28 and highlight key points

Read pg 29 as well
