Bacteria Madness

This week's homework: What a List!-
If you don't have a notebook, shame on you!

-Text: Bacteria, Chapter 19 section 1; answer questions in study guide

-30 minuteVideo: http://www.learner.org/vod/vod_window.html?pid=1370
  Here's the trick: click the button "VOD" for episode 8-Microbial Ecology, which will send you to the exact same page; then click that same button, and you should get the pop-up to watch.  I don't know why it works that way, O well.

-Start the new experiment with your petri dishes and ecocolumns.

-Limiting Nutrient experiment write-up: if you've lost your worksheet, go to page 81.  Describe the Problem, state your hypothesis and answer questions 1-4 from Analyze and Conclude.

-Turn in your cinquain or other type poetry about the pond trip. If you have not done so yet, work on those worksheets handed out when we started the ecocolumns.  Bring your folders to class on Thursday; we will "workshop" these a little.

-Extra Credit:  find a current event about bacteria (ideas-- bacteria generating hydroden for fuel cars, bacteria cleaning up oil spills, or just google "news bacteria technology", for example.)  Or find a youtube video on bacteria that you think will be helpful  or interesting for your classmates.  Extra credit is good for your grade and will also result in a donation to buy a goat for a family in Africa.

Current Events Plus +++++ Homework

First of all for homework there is the current event, which must be about a topic in biology; find an article online using one of the sites in the side bar, and be prepared to summarize it for the class and answer any questions from the class about it--you may use a 3x5 card for notes, but not read directly from the article.  Try for a 3-minute presentation.

From the Textbook/Study Guide:
Chapter 4.3 and 4.4  Land & Aquatic Biomes (2 sections) to complete by next Monday--No extra homework on Friday other than to change the water according to last Friday's directions, and to make observations.  Be on the lookout for :  different niches in your ecosystem, any ecological succession (when a new species starts to become more dominant), food chain & web, biotic & abiotic factors, everything we discussed in class, actually.  Keep notes.  Write that poem/cinquain about the pond observations.   Also observe your vials containing the limiting nutrient.

Keep up with the vocabulary for chapter 4: http://quizlet.com/4992488/prentice-hall-biology-chapter-4-flash-cards/

Click the Aquarium

Friday is Fish Day! Remember to change the water--use a kitchen baster to remove 1/4th of the water and replace it with settled tap water.  Make observation.

Sorry that none of the lab work yesterday was very decisive--sometimes it's like that.  I cannot vouch for the pH paper or the nitrate/phosphate testing kit; it was passed on to me by a friend and I'm not sure if those things go bad???  But perhaps, contrary to expectation, the water is good?!?

Remember to put your vials in a cool place which receives sunlight (not your backpack) and to take observations.  I saw a number of science worksheets in the room yesterday; if you lost your paper then look up the experiment in chapter 3, and the questions are the same.  This is to turn in after you've finished the observations.  Please re-read the directions and questions to be sure of the main point, which sometimes gets lost in the bustle of the lab.
Reading homework is Chapter 4.2, answering questions from the study guide.  Quizlet can help you with the vocabulary practice.  Also, The Cartoon Guide: read chapters 1-2. 


Did you click the aquarium?

Mystery of the Floating Fish?

For your ecosystem notebooks, answer these questions:
How does the ecosystem model  the water cycle? How is it different?
How does it model the carbon cycle? How is it different?
How does it model the nitrogen cycle? How is it different?
How does it model food webs and food chains?
http://www.learner.org/courses/essential/life/bottlebio/ecocol/pdf/foodweb.pdf


The study chapter 4.1, answering study guide questions & vocabulary.
http://quizlet.com/2433336/ch-4-ecosystems-and-communities-flash-cards/(optional)

For your ecosystems notebook, answer:

How does the ecosystem model greenhouse gases? How is it different?

Comment today: Why did they die?  Comment on why your fish did or didn't make it, and any new signs of change you are observing.  (Please sign your name.)

ALSO THIS: Please bring a water sample from your ecocolumns to Thursday's class, about 120 mL or 1/2 cup.

Are Your Bottles in the Car!?!

 Today is THE DAY to finish setting up your ecosystems (all three levels), and your system of observation-taking.  First of all, WHERE are you going to keep it where it will be remembered, where it will get indirect light but not in the direct sunlight, and where it will NOT get knocked over?  And WHEN will you make your daily observations?  WHAT is it that you will be looking for?   This is what you will write a comment on below.
However, that is not enough.  Now is the time to read your Handouts and begin to fill in the first pages.  Set aside a good portion of time today to do so, so that we can get off on the right foot.

PRINT THIS OUT NOW  - THE DIRECTIONS ARE HERE:
http://www.learner.org/courses/essential/life/bottlebio/ecocol/takinginventory.html


If you have lost the handouts, here is a link:
http://www.learner.org/courses/essential/life/bottlebio/ecocol/pdf/takinginventorydata.pdf
http://www.learner.org/courses/essential/life/bottlebio/ecocol/pdf/ponderingchangedata.pdf

THIS IS OUR STARTING POINT, SO GET THIS READ AND DONE RIGHT AWAY.  I think you should find a folder to put all your papers in for this project, as it will last for 4-6 weeks.

ALSO: Now is a good time to take a photo. (Part of the assignment, not a suggestion.   :)

So Here's the Test...

The moment you've all been waiting for... first science test of the year!!  So, after you have reviewed adequately, you may proceed to page 57, the Chapter 2 Assessment, and answer these questions in sentence form.  By that I mean, the answer to #1 is not "d" , but rather "The positively charged particle in an atom is the electron."  All answers should be in complete sentences and should reflect the question asked.  ( For example:
Describe the parts of the nucleotide. ||  "Nucleotides consist of a 5-carbon sugar, a phosphate group and a nitrogenous base."  Therefore it is not necessary to copy the question.)

These are the questions to answer: This is an Open book test.
1-19, 22-25, 28,31,35
 
On Thursday we will complete the test (not open book) on the vocabulary of chapters 1 & 2, plus some multiple choice questions.  For help studying vocabulary, go to quizlet.com : http://quizlet.com/1229738/biology-chapter-2-prentice-hall-2008-flash-cards/

Please read and re-read these instructions so that you understand completely the directions.
