Pig Heart Dissection- Wednesday May 1st

Please take some time and look over the Pig Heart Dissection powerpoint below.

Pig Heart Dissection Powerpoint

This will be just like the one we will complete on Wednesday.  Be familiar with the names and parts.

Monday April 29th - Wrapping up the Circulatory System

Hi All,

Today we are finishing up our work on the circulatory system.

Here is a review video to watch on the blood flow.



After you are done watching this you can go to this link and complete the interactive quiz.
Label the Heart

Here is one more link from Nova on the Human Heart.

Here is the image of the hear that you will use to trace the blood flow.  Remember you will have a word ban kto help you out, but you need to identify the parts and how the blood moves.

Wednesday April 24th - Heart and Blood Flow

Today we reviewed the structure and function of the circulatory system.

We also introduced the heart.  Specifically we looked at the parts of the heart and how the blood flows through it.

Here are some pictures from the work we did today.

Monday and Tuesday , April 8 and April 9th 2013




Hi Everyone,

As we thunder towards April Vacation I must stress how impressed I am with how productive you have been over these past few weeks.  Great work on your labs too, I look forward to reading them all this week!

Some reminders of things to be working on:

1. Photosynthesis and Respiration Comics (due Tuesday)

2. Review Cell Processes Study Sheet (Quiz on Thursday)

3. Also think of some arguments you might make as to which cell process is ore important to human existence--Photosynthesis or Respiration?  Hmmmm......

Keep up the good work and know that your teachers appreciate your efforts!

Yeast Fermentation Lab!

Scientists,


Well done today with the lab despite the fact that we did not see the results as quickly as we might have thought.  Some of your labs actually came out quite well!  Unfortunately you were all out the door and starting your weekend fun before you could see it!!

Good science means that we are always "tinkering and experimenting" for ways to get results with our labs.  Why do you thi nk we saw faster results when we added heat and more yeast to the beakers?  We can explore this more on Monday!


For those of you who would like to get a head start on the Post Lab Analysis here is an image of what your beakers looked like before the fermentation took place and what they looked like after:

AFTER:

Click on the images to enlarge them, but from left to right it is the water, the Powerade, the fruit punch, and the Hi-C.

Enjoy the weekend and be sure to email Mr. Greg with any questions you might have about the lab or the comics!

Friday April 5, 2013 - Study Guide

Here is the study guide for the Assessment on Cell Processes.

Be sure to fill this out over the next few days and check in with your teachers on any questions prior to Thursday April 11th.

Yeast Fermentation Lab

Greetings Scientists,

On Friday you will be conducting an experiment to observe the evidence of yeast activity.  Before performing the lab, you must take the time to answer the Pre-Lab Questions from the handout given to you today in class.  The link to the reading "Chapter 15-Investigating Fungi II--Yeast" will help you answer these questions.  Be sure to read pg. 180-182 and the Lab Instructions!

Chapter 15-Investigating Fungi II--Yeast

The Pre-Lab Questions must be completed by the start of class on Friday for you to do the lab.

Good Luck!

We had some excellent discussions today about the relationship between photosynthesis and respiration.  It is always great to see that a lot of critical thinking is taking place!

During class, we talked about fermentation including alcoholic fermentation in yeast and lactic acid fermentation in the muscles of humans.

Also, we kicked off class with a gallery walk for students to share their illustrations and poems depicting photosynthesis and respiration.  Here is a lovely example of student work:

Greetings Everyone,

Today, we took an interactive trip into an animal cell (via iCell) and took a closer look at the mitochondria of the cell.  We learned back when we first started working with cells that the mitochondria are known as the "powerhouses" of the cell.  Today, we were able to connect that analogy with the fact that mitochondria are essential to respiration.

We also took the time to compare and contrast respiration and photosynthesis.  The students used their Venn Diagram's from Monday night and helped me make a Double Bubble as seen below....

Tomorrow, I look forward to seeing the creative drawings and writing pieces that students put together to demonstrate the relationship between photosynthesis and respiration!

MAJOR EXAM TOMORROW WORTH 95% OF GRADE!












....April Fools!
(Mr. Greg is so lame...)


What's no joke is how well both classes worked today as we started to shift our focus from one cell process to another and are now looking at respiration.

Now that we know cellular respiration is a series of chemical reactions by which energy is released from sugars with the use of oxygen; heat is a waste product of the thousands of respirations taking place in the mitochondria of your cells.

The following link includes what we read in class today (it is always a good idea to refresh!) as well as some extra reading that will help you with your Photosynthesis vs. Respiration Venn Diagrams you are making tonight!


Looking forward to another great day tomorrow.  Keep up the good work!
