Cells Unit Test

Please REMEMBER there is a CELLS UNIT TEST on Wed, Feb. 10.

Topics:

  • Types of cells (eukaryotic vs. prokaryotic; animal vs. plant)
  • Structure and function of cell parts (cell wall, cell membrane, cytoplasm, nucleus, chloroplast, mitochondria, vacuole)
  • Compare and contrast plant and animal cells
  • Describe the observable components and functions of certain organelles of the cell
  • Make connections between organelles and the basic life processes (photosynthesis, respiration, fermentation, diffusion, osmosis)
  • Justify that the cell is the basic unit of life and carries out life functions
  • Make sense of how cells form tissues, tissues form organs, and organs form organisms
  • Describe/predict the movement of particles in and out of cells (osmosis and diffusion)
  • Describe the processes of photosynthesis and cellular respiration/fermentation and justify their importance to life
  • Compare and contrast breathing and respiration
  • Compare and contrast respiration and fermentation

You should be studying from the following resources:

-All column notes from discussions

-Labs (Microscope, Plant & Animal Cells, Diffusion, Respiration/Fermentation)

-Book (Chap. 1 Sec. 1, 2 (only those structures we have studied), 4   Chap. 2, Sec. 1,2)

SAM Animation Directions!

Your SAM Animation is due on Monday or Tuesday if you are in Science BLUE. You must have the following completed BEFORE you walk into Science class. If you have questions, please ask Ms. DeCardy.

1. Export your SAM as an MPEG4 or QuickTime movie
2. Put your movie on the portal
3. Embed your movie into your blog

Watch this video for directions on how to do each step above!

Enrollment Survey Reminder

Letter from the Admission Office

Dear Parents,

Each semester, we send to you a survey that asks if your child(ren) plan to return to SAS the following semester. In the past, the Office of Admission has sent this paper survey home with your youngest child. With the launch of the Parent Portal, we will “go green” and conduct the survey via PowerSchool. Please click on the survey for each child and tell us whether or not your child(ren) will return to SAS for the fall semester of the 2010-2011 school year.

You will need to complete a survey for each child and it is very important to complete the survey no later than Friday, February 12th.  As this is essential information that we use when planning for the next school year, if you do not respond to this request, we will contact you by phone or e-mail after the due date.

If you have any questions, please contact the Office of Admission at tel.: 6221.1445, ext.2525 Daniel Dong, Puxi campus or ext.3305 Eileen Shen, Pudong campus.

Best regard,

T.K. Ostrom

Director of Admission

IMPORTANT PowerSchool Update:

1.Enrollment Survey. All enrollment surveys will be done online in PowerSchool through the Parent Portal. This enrollment survey is for next school year – 2010-2011. We will not be sending the enrollment survey form through your youngest child anymore. You will receive an email from PowerSchool regarding the details.

2.Emergency Contacts – You can now update your emergency contacts in PowerSchool. Just click the Demographics Update and scroll down to see the emergency contacts and where you need to enter the information. It is important for you to provide two emergency contacts.

Photosynthesis/Respiration Animation

2213996356_4224acc609

Today I assigned the Animation project for Photosynthesis and Respiration.  You will participate in a tutorial session with Ms. DeCardy on Tuesday during ELO and have some part of Thursday’s ELO to work on it.

The project will be due to the dropbox on M, Feb. 8 and T, Feb. 9.

Please see the attached assignment sheet and rubric.

Animation Project Assignment/Rubric

The Lab Report

gummi

So, we have been doing lots of microscope work looking at cell structure and function and similarities between plant and animal cells. You have studied the processes of diffusion and osmosis and can apply it to a cell (and a gummy bear!).  The experiments you have designed with those gummy bears were really interesting, but had such varying results.  And, you have now practiced how to develop a well-written lab report so that your experiment is viewed legitimately.

Now its time to design and document some well-controlled experiments.  Over the next week, we will isolate one variable that might affect diffusion of water into a gummy bear.   Just you case you need them, here are some helpful resources:

gummy experiment extension

The copy of the lab report packet is too big of a file too put on the blog.  You can access a copy of it on the apple server in the MS shared files.  You can also use the The Lab Report Tab at the top of my blog.

Start of Quarter 3

cheek-cells

Welcome back from the winter break!  We will now be moving into a study of cells.  We will spend about 4-5 weeks understanding cells and their processes like diffusion, osmosis, photosynthesis, and respiration.  We will be doing a lot of work with our digital microscopes and you will get to design and conduct your own experiments this quarter.  I look forward to helping you explore the microscopic world of cells.

Links to use for Pompeii Day

These You tube videos have footage of an eruption of Mt. Etna.  While it is not Mt. Vesuvius, it is a similar volcano type with similar eruptions.  You can use it has backdrops for your videos.

Etna –  pyroclastic flow

Etna – good explosion and smoke/ash

Etna – close-ups

Science Essential Questions

For science essential questions:

Answer the following essential questions as 2 separate posts on your own blog.  Answers should be thoughtful, reflective, and supported.  Use details from our unit and science vocabulary as much as possible.  Title each post as Science Essential Question #1 and #2.

1)  How would you feel if your home were destroyed by an earthquake or volcano?

2)  Why is it important that the dynamic nature (plate tectonics and what it causes) of Earth be respected?

Pompeii Day Webquest

In order to get ready for Pompeii Day, you will need to complete a webquest (see link below) and find out more information about the eruption of Mt. Vesuvius in 79 A.D.  Answer the questions directly on the webquest document and turn it into the MS dropboxes next class.

…and get ready to put on a toga and pretend that you are a Roman citizen right there when Mt. Vesuvius erupts…Pompeii Day coming Dec. 16 & 17!!!

Class Discussion Survey

Please take a minute to help me become a better teacher by taking the embedded survey. All of the questions have to do with our discussions in science.  Please answer the questions honestly.  Be sure to hit “submit” when finished.
