GPS -SB1: Cells- Students will analyze the structure and functions of cells.

Objectives:

EQ: How do the cells in living organisms control or affect homeostasis (the internal environment)?

·       Key question – How can I identify the parts of the cell?

·       Key question – How does each cell function “what role do they play in maintaining homeostasis?”

EQ2: How does cancer cause cells to die?

·       Key question -What factors control cell growth?

·       Key question- What kinds of factors may lead to a cell becoming cancerous?

Introduction to Cells

Welcome to the fascinating study of cells. Cytology and Histo-cytology - are the study of cells.

 Cyt- means cell                                 Hist -  means past patterns

 

Background:

Scientist use histo-cytology or histology to study the patterns and conditions that affect the growth of cells such as:

• *cell structure
• *homeostasis
• *virus, bacteria and fungus attacks (pathogens)  path- means process to a disease
• *genetics
• *evolution

Instruction: Today you are going to become cell biologists and study the parts of the cell and the functions that each “organelle” (small helper) in the cell.

Cell theory proposed  Schwann heard Schleiden as they described plant cells with nuclei, Schwann was struck by the similarity of these plant cells to cells he had observed in animal tissues. Schwann was mostly right.

·        1)  The cell is the unit of structure, physiology, and organization in living things. (right)

·        2)  The cell retains a dual existence as a distinct entity and a building block in the construction of organisms (right)

·        3)  Cells form by free-cell formation, similar to the formation of crystals (spontaneous generation). (wrong)

Rudolph Virchow's powerful dictum, "Omnis cellula e cellula"...  "All cells only arise from pre-existing cells".

Today’s Cell theory states:          
   1. all known living things are made up of cells.
   2. the cell is structural & functional unit of all living things.
   3. all cells come from pre-existing cells by division.
            (Spontaneous Generation does not occur).
   4. cells contains hereditary information which is passed from
              cell to cell during cell division.
   5. All cells are basically the same in chemical composition.
   6. all energy flow (metabolism & biochemistry) of life occurs
              within cells.    [GPS- SB1 & SB2}]

GPS:  SB1.c & d: Structure and function of living cells. 

These key concept questions will help the student to understand the basis make-up and function of living things:  What is/are__________________________?

                            *Biochemical Processes

                            * macromolecules

                            *matter

Furthermore, these key topics will help you to answer the fundamental/ essential question of how do living things maintain an internal balance called homeostasis that allows us to succeed in our environment. 

Instruction:

 SB2:Today we will begin to look back at what we have accomplished thus far:

        What is Biology? What are the Characteristics of Science Thinking, Reasoning and Writing (Scientific Method - where's your abstract for your nutrients lab!!!) What are the foundations of biochemcial principles like parts of the atom, periodic table, chemical bonds, macromolecules (Protein, carbohydrates, Lipids and Nucleic Acids) and other organic molecules. EQ: How do all these processes fit into regulating Homeostasis?

                    * Dehydrogenation Synthesis

             * Hydrolysis

            * Metabolism = catabolic and anabolic processes (equals Homeostasis)

            * Valence Electrons determine how a chemical is going to react (Ionic, Covalent and hydrogen-hydrogen bonds, Van der Wall forces)

Instruction:

* Warm-up (Centers)

* Review Student Check /Review of Powerpoint.

SEV 1-2- The Cycling of Matter through the Environment; The Interconnected World

SEV4 -continued.  Alternative Energy sources to reduce the demand for non-renewable resources and to increase sustainable living.

ENSCI- Here's where we have been, where we are and where we are headed:[Unit Plan]

Covered- EQ's:

What is Environmental Science? We addressed key concepts such as questions such as the definition, how other sciences incorporate affect environmental aspects, and global issues affecting the GNP such as the needs for industrialized and high developed countries vs. the needs of low developed countries.

Why is Environmental Science important to your future? What kinds of jobs, technology and life style changes will I need to prepare for in the years to come?  You are already preparing for your future and you are learning ways to: be eco-friendly, reduce your carbon footprint, educate other people including family and friends on environmental issues/impact; including how to refuse, reduce, reuse, and recycle. You are designing projects that will positively impact your home, the school or community. You are researching alternative energy sources such as solar energy and recycling. Finally, you are and actively participating in sustainable living concepts like building and monitoring your organic hydroponic gardens.

Present and Future Unit Plan Standards

SEV5. Students will recognize that human beings are part of the global ecosystem and will evaluate the effects of human activities and technology on ecosystems.

SCSh 1-9: Information Literacy (reading, writing and academic vocabulary)

For the next three weeks  we will explore "human beings are part of the global ecosystem." To better understand the essential question of "how do we as human interact and impact our ecosystem," we must first address key concepts such as the cycles in nature, changes in nature, population shifts, our interconnection to the environment. These topics will help you to evaluate the effects of human impact like...is it necessary to intervene in the processes of nature? If we do, how do we proceed to maximize the beneficial outcomes and minimize the negative environmental impact? At what cost and sacrifice to nature are we willing to risk? Will the overall greater good outweigh the immediate financial expenses or short term "cost"? What is meant by cost?

Instruction:

1) I must stress upon you importance of meeting deadlines in a business environment. We have a concrete deadline of Friday, October 2nd for proposals to be submitted to Dr. Miletto.  (Ms. A to elaborate) You will be asked to complete outside work (just like in any business situation and at your time expense). We will lose clients and our reputation is at stake if we do not produce quality product.

2) Today we will be infusing new information on the Cycling of Matter in the environment (centers) with continuing monitoring our plants and working on our summary page. Step 3 in the proposal is Creating an Itemized Budget. The budget draft will and edited summary page are due Friday.
