Toxicology Lab

10/29

The shrimp are hatching! Bring substances tomorrow!!!


Here's the format for the risk assessment for five household test substances you are bringing to school. "Description of risk" should include product information. "Consequences" should be possible health effects.

All of this is part of your lab report for the toxicology lab. Make sure your Introduction and Procedures are written before you start testing on Friday! 

The final lab report is due on Wednesday,  November 4th.

Offrenda projects must go up Monday. 
You can write this on the back of your prelab LD50 calculation sheet.

Offrenda project!






Dia De Los Muertos: Due Monday, November 2

Create an offrenda for the Environmental Scientist of your choice. Groups of four, no two environmentalists alike. Sign up on the window in the hall. 

Here's some information about ofrenda's:


Ofrenda y Dia de los muertos Rubric

Las ofrendas del día de los muertos

As a class project, we will be creating ofrendas (or special remembrance tables) to venerate environmentalists, naturalists, and environmental scientist. This list includes KEY policy makers, and citizen scientists.
The Mexican tradition of creating ofrendas during the Day of the Dead is an ancient tradition of honoring, remembering, and celebrating the lives of those who have passed away. The creators customarily use a variety of objects and their own creativity to create a display that would attract and please the spirit of the loved one and bring back fond, pleasant memories for those that are celebrating. In Mexico, as in the Unites States, death is a painful, stressful time. The Day of the Dead, which is celebrated October 31st –November 2nd, is a way to temporarily put away the sadness that comes with death and truly rejoice in the memory of the deceased.
In creating our ofrendas, it is our purpose to create something that reflects the positive attributes of this traditional celebration and the people we choose to honor for the enrichment of our cultural understanding of the Mexican community. It is our goal to learn about the traditional elements of these ofrendas and to recreate the celebration as a way of experiencing authentic Mexican culture. It is not our purpose to define or celebrate any individual religion or belief, nor is it a means to glorify death.

Students may and/or should use the following in addition to traditional items:

  • 3 different levels
  •  cloth, lace
·
Remember to consult your notes over the traditional elements when planning!food, drinks
· flowers or plants (live or fake - especially marigolds)
· herbs (especially sage) and salt
· “papel picado”
· skeleton artwork, papier-machés, etc. (we will make calaberas)
· handmade signs, crafts, cards, etc.
· artwork (drawings, paintings, sculptures - original or famous)
· stories, poems, or letters
· photographs
· personal items (such as albums, clothing, books, etc.)
· music
· candles, incense and or lights

Día de los muertos will take place at the school, and the table or boxes used should be covered with cloth. Self-contained ofrendas will be easiest for clean up.


Set up times for your ofrenda:
Wednesday October 30th during class.
Ofrendas must be on display by 4:16 on Wednesday Oct.30th.
All ofrendas must be broken down and/or collected 6:00 pm Wednesday, Oct. 30th. Any left after six will be discarded.
Ofrenda rubric

In order to get a perfect score you must follow all directions. The ofrenda must be creative, original and neat. It should reflect the tastes of the person who it is honoring and show an understanding of this Mexican tradition by including at least ten traditional items.
The ofrenda contains:



1. At least ten cultural items (List to be attached to your ofrenda)
2. At least 5 personal items unique to the individual being honored (List to be attached)
3. At least three levels
4. An arch
5. Two paragraphs telling visitors why you choose to honor this person. Includes major contributions to Environmental Science.

6. Papel Picado
7. Dead Bread (pan de muerto)

An additional 20 points for: 
Set up and clean up: 5 points
Professional tours:15 points

Master=4 points
Apprentice=3 points

ISHMAEL RESPONSE PROJECT DUE NOVEMBER 6


 
 
 

 
AP Environmental Science


 
Use the rubric to guide your response project. Your project must be approved to go forward. If I have not approved a project, you must see me in tutoring immediately to get that approval. Please don't try to catch me about this in class. I gave you class time to work on this, gave you comments, now you must take initiative and get this done. 

If I have not approved a project by this Friday, then you cannot do it this six weeks, but may see me in tutoring to try again next.

This project is worth two project grades. You can produce just about anything you wish, as long as you have approval. Feel free to Google, "literature response projects," for examples and ideas. There are lots of Ishmael response projects on the internet.

This project must be viewed by at least five people with comments from at least two in order to meet minimum requirements for audience.

GOOD LUCK!!!

Socratic Wrap 10/5-10/9

10/9/2015

Email me CHAPTER 6 QUIZ some of you still need daily grades this week.


Today's seminar should be 15 minutes! Time it so you can use the remaining time to wrap.

This week we had four seminars, and your wrap should consist of:

4 debriefs
4 self-evaluations
2 partner evaluations

Instead of writing a summary, create a flow chart/concept map tracking Ishmael's explanation of Taker and Leaver cultures.

Include on your map: Adam&Eve, Cain&Abel, The ABC's, Semites, Ishmael, The Narrator, the gods, tree of life, tree of knowledge, indigenous peoples, the early aeronauts, law of natural selection, law of man, population control, unregulated growth.

And anything else that you can recall. Use arrows to show how one idea relates to the others.

This is a project grade. Some of you still need a project grade.


Finally, look back over your evaluations from previous weeks. Answer the following: 

What changes do you see?
Has your interest and participation gone up or down? 
What are your goals for the last week?


Thanks again for embarking on this journey with me. I sincerely hope our exploration of this book will help us dig deeper into the topic of Environmental Science. I may or may not agree with everything in Ishmael, but I do believe that turning on our brains is the key. We have to past the trite messages, "Save the whales!" etc., and delve deeper, really get our hands on (who said this, Esmerelda?), and find sustainable ways to live.   

Priscilla asked me one day, "Do you think that this book is really about activating those parts of our brain that we don't use?"

And the best I could say is, "Quite possibly."


All I know, is that yesterday, when I thought fourth period hadn't read, and wasn't really processing, your writing showed me that you were. Keep going. I can't wait to see what get said tomorrow when I'm not there. Someone record that seminar (if you can convince the sub that it's all right by me).  

I refuse to read the Cliff Notes, and I sincerely hope you will stay away from them and think for yourself. Speak your own mind, regardless of the grammar and spelling.

 CHAPTER 6 POPULATION BIOLOGY powerpoint
Chapter Overview

The AP student needs to be competent in exponential and logistic growth curves
and the implications of each including the concept of carrying capacity. Type I, II
and III survivorship curves, characteristics of r and K -selected species, and
examples of each should be learned. Students need to know biotic and abiotic
factors in the environment and their role in determining population size.
Applications of conservation biology should be understood.

Key Concepts

6.1 Explain exponential growth and logistic growth.

6.2 Compare and contrast the factors that regulate population growth.

6.3 Summarize the characteristics of r-selected species and K-selected species.
Applications of Type I, II, and III survivorship curves

6.4. Understand the difference between density dependent and densityindependent
factors.

6.4 Identify some applications of population dynamics in conservation biology.
Use the Rule of 70 to calculate doubling time and growth rate.
