Gchat Review
Hello Biology students!
The Gchat review will be scheduled for 6:00-8:00 p.m. this evening. 5 o'clock proved a little too early to prepare, so we will begin one hour later and end after two hours.
See you then!

Worm Lab Dissection Video
Hello Biology students!
Below is a video from today's identification portion of the Worm Lab, outlining a few of the structures you will be held accountable for on the practical exam. I apologize for the semi-low quality, as we did not have our main camera on hand today.
A big thank you to all of the students involved in today's recordings -- great work!

Let the Dissections Begin!
Hello Biology students!
Today we begin the process of laboratory dissection, which will carry on through the end of the year as we study the kingdom Animalia.
Our first dissection lab will study the common earthworm. Below is a very general image of some of the structures you will be looking for both today and tomorrow. More images will be available to you in-lab and on the blog as well, so keep checking back for updates. Also, there will be a worm dissection video published soon.
Good luck!

Sponge Filtration
Hello Biology students!
Well, here we are -- Kingdom Animalia. Before you know it, you will be elbow-deep in dissections, but first we will start with the common sponge and it's relatives in the phylum Porifera.
Below is a video demonstrating the filtering powers of the sea sponge. Be sure to take a look at Chapter 26, Section 2 in your book after watching this video for a complete look at the anatomy of a sponge, which we will touch upon in class this week.
In the meantime, enjoy the short film, and interesting music too.

A Bit About Tropism
Hello Biology students!
In lab, we have been keeping a close eye on the little seedlings we "planted" in our petri dishes earlier this week. As you observe their growth, keep in mind the variables involved in the growth direction, and also how we tried to limit other variables too.
The video below offers a glimpse into what is actually going on -- take a look, and consider it in the context of the current lab. Enjoy!

"Green Sheet" Reminder
Hello Biology students!
The Chapter 22-25 LE is fast approaching, so it would be a great idea to study your "green" review sheet if you have not done so already, and ask questions about the material asap. Waiting until Thursday to look the sheet over is not a good idea, so plan accordingly!
We will be moving through the in-class portion of the material fairly rapidly, so please keep that in mind as you plan your week's schedule.
If you have any questions, please let me know!

The Paramecium
Hello Biology students!
Today, you became fairly acquainted with the tiny organism called paramecium. This "cute" (your classmate's words, not mine) organism is a great example of a ciliated protozoan that exhibits simple structure and behavior, but is oddly complex at the same time.
Below is a video of the paramecium taking in nutrients in the form of a stained yeast. If you have the option, press the "HQ" button on the menu to view the clip in higher quality.
Pay specific attention to what happens after the food has been in the paramecium's system for a little while. What do you notice? What would explain this change?
Think about it, and I'll ask you for your answer tomorrow in-class. Good luck!
PS - Please excuse the music. =)

Double Helix
Hello Biology students!
This week is definitely going to be an interesting one, as we take a deeper look at the structures we have become familiar with in chapters 10 and 11: chromosomes.
We start the week by finishing the Double Helix movie we started last week--a film by the BBC which gives attention to the climate of the times in which Watson and co. pushed to find a structure for the all-important DNA molecule.
When watching the film, keep close attention to the competitive nature of the individuals involved, as well as their personal presentation, and the director's take on each of their personalities. We'll discuss the accuracy of the work on Tuesday.
Enjoy!
