Week 9 macromolecules – carbohydrates and proteins


10/13/14
Qfd: Making one person smile can change the world – maybe not the whole world, but their world.
Essential Question of the day: compare and contrast mono and polysaccharide molecules by proving 3 written examples
Todays learning objective: <strong>Students should know and be able to demonstrate comprehension on multiple levels concerning: Amino Acids, protein structure and function, transcription and translation of proteins, and cellular respiration by responding to others using Google classroom , asking pertinent high level questions, and answering using higher level processing skills

1) finish carbohydrates worksheet turn in using google classroom by tomorrow

Qfd: Saying someone is ugly doesn’t make you any prettier.

Todays learning objective: <strong>Students should know and be able to demonstrate comprehension on multiple levels concerning: Amino Acids, protein structure and function, transcription and translation of proteins, and cellular respiration by responding to others using Google classroom , asking pertinent high level questions, and answering using higher level processing skills
1) carbohydrate testing and discussion of handout
2) lab
Lab Objective:
To build a model of the cell membrane.
To investigate how the cell membrane regulates what moves into and out of cells.
Research Questions:
What molecules of the cell membrane do the cotton swabs represent?
If a molecule needs to enter or exit the cell and it cannot fit between the phospholipids how can it cross the membrane?
The cell membrane is a barrier that separates a cell from the external environment. It controls the passage of materials into and out of the cell. The membrane is made up of a double layer of phospholipids, called the lipid bilayer. Scattered between these phospholipids are various other molecules such as protein channels, pumps, cholesterol, and carbohydrate chains. With the cooperation of the phospholipids and other embedded molecules the passage of molecules into and out of the cell is controlled. Think of the cell membrane as the exterior walls and roof of your home. It’s scattered with a number of windows, doors and vents. Just like the cell, these items help to control what enters and exits your home.

Materials:
3 pipe cleaners of different colors
1 regular-sized drinking straw
Thick, medium-size rubber band
Approximately 50 cotton swabs
Scissors
1 marble
1 BB
Experimental Procedure: what does a cell membrane look like by building a model of it
Gather the cotton swabs into a bundle and place the rubber band around the middle to keep them in a bundle.
Place a receptor molecule into the cell membrane.
Take one of the pipe cleaners and place it through the bundle of cotton swabs.
Bend one end of it into a circular shape. This shape represents how signal molecules bind to specific molecules. Only a circular-shaped molecule can bind with this receptor.
Use the second pipe cleaner as a carbohydrate chain. Place it in the bundle of cotton swabs, just as in step 2. Don’t bend this pipe cleaner.
Cut your drinking straw in half. Place each half into different locations in the bundle of cotton swabs. These represent the protein channels and pumps.
Holding the cotton swabs vertically, place the marble on top of the swabs. Does it pass between the swabs? Why or why not?
Place the marble on top of the straw. Does it pass through the straw? Why or why not?
Still holding the cotton swabs vertically, place the BB on top of the swabs. Does it pass between the swabs? Why or why not?
Place the BB on top of the straw. Does it pass through the straw? Why or why not?
Place your mouth on the cotton end of the swabs and blow. Can you feel air on the other side of the swabs? Why or why not?
Explain how the swabs and straws actually represent the components of the a real cell membrane.
Roll the bundle of cotton swabs between your hands. Do the individual swabs move? Without pulling the straw out can you move it between the swabs? How does this represent the fluid mosaic model?
Terms/Concepts:Cell; Cell membrane; Phospholipid; Receptor and signal molecule; Selective permeability; Protein channels; and pumps; Carbohydrate chain; Fluid mosaic model
Build a cell membrane in 15 minutes using all the materials on your desk
1) which part represents the hydrophillic part?
2) which part represents the hydrophobic part?
3) Name an ion that passes through the cell membrane?
4) Which part represents an ion passing through the channel?
5) which part cannot pass through the cell membrane?

Qfd: Life is 10% of what happens to you and 90% of how you react to it.
Essential Question of the day:
Todays learning objective: <strong>Students should know and be able to demonstrate comprehension on multiple levels concerning: Amino Acids, protein structure and function, transcription and translation of proteins, and cellular respiration by responding to others using Google classroom , asking pertinent high level questions, and answering using higher level processing skills
1) quiz

complete lesson 2.1 only tonight as hw or after quiz

10/16/14
Qfd: Never do something permanently foolish just because you are temporarily upset.
Essential Question of the day:
Todays learning objective: <strong>Students should know and be able to demonstrate comprehension on multiple levels concerning: Amino Acids, protein structure and function, transcription and translation of proteins, and cellular respiration by responding to others using Google classroom , asking pertinent high level questions, and answering using higher level processing skills


1) I will demonstrate the goals of today’s objective
2) we will watch a video on proteins while taking notes for a summary and objective
3) you will write a summary 3-5 sentences of what you learned from these videos concerning protein synthesis and then ask another student in the classroom a question and answer the one given to you as well using google classroom

10/17/14
Qfd: If you really want to do something, you’ll find a way. If you don’t, you’ll find an excuse.
Essential Question of the day:
Todays learning objective: <strong>Students should know and be able to demonstrate comprehension on multiple levels concerning: Amino Acids, protein structure and function, transcription and translation of proteins, and cellular respiration by responding to others using Google classroom , asking pertinent high level questions, and answering using higher level processing skills

1) due article on flu google classroom , due protein discussion
2) lipids

  1. Mr.Borden i was wandering if i get full credit or not because my chrome book wasn’t working and i didnt have time to share my homework with you. My question is would i get full credit still or not?

    • No you will lose 20 points for it being late , it should been sent in before yesterday.

  2. Mr.borden for homework tonight do we have to do the questions on the back of the work sheet you gave us or just the foldable?

    • Yes that would be great and save you time over the weekend
