Amatuzzi CP BIO MOLECULESOF LIFE PROJECT 100 points

THIS PROJECT IS OPTIONAL, but will still be graded. (IT IS NOT “EXTRA” CREDIT)

Only do it if you want an extra grade. Do NOT do a poor job, or it will lower your average.

May work individually or in teams of two, but understand that BOTH partners get the same grade, regardless of division of labor.

A major focus of biology today is understanding how individual molecules function in living things. This project highlights some of these molecules and provides you an opportunity to use creativity and personal choice to demonstrate your learning.

There are THREE parts to this project: a model of the molecule, a typed report with specific information, and an oral presentation. A copy of your report must be submitted toTurn It In.

Choose ONE of the molecules listed.

Show STRUCTURE, INDIVIDUAL ATOMS or, for larger molecules, COMPONENT PARTS.

LABEL (on the model) components or atoms.

You must clear your choice with me because each student/team will do a different molecule.

1.Glucose or Fructose – show all atoms

2.Sucrose or Lactose – show all atoms

3.A portion of a polysaccharide

a. starch – show branching chains of glucose

b. glycogen – show branching chains of glucose

c. cellulose – show hydrogen bonding between parallel chains

4. A specific amino acid with a complex side group– all atoms

5. A specific saturated fatty acid – all atoms

6. A specific unsaturated fatty acid – all atoms

7. Triglyceride – show monomers and functional groups involved in bonding

8. A section of a phospholipid bilayer

9. A steroid - show four carbon rings and atoms or groups attached to it

a. cholesterolc. testosterone

b. estrogend. cortisone or prednisone

  1. DNA – at least 10 base pairs in a double helix

11. RNA – at least 10 nucleotides in the chain

12. ATP – all parts of the molecule

13. A protein – show polypeptide,3-dimensional shape

a. hemoglobinc. an antibody

b. insulind. lactase enzyme

**Show me the structure/picture of your molecule before you start your model.

MOLECULES OF LIFE PROJECT – CRITERIA PROJECT DUE DATE:______

Date assigned ______PREP WORK* DUE: ______

PART 1: Choose ONE way to present your molecule. (30 points)

A.Three-dimensional model

  • Must be large enough scale to show components or atoms clearly
  • Components or atoms must be labeled on the model (NOT a key somewhere else)
  • Must be constructed securely (I may use it in class as visual aid or demo)
  • Must be permanent (no perishable parts)
  • An index card with name and picture of molecule(model, not structural formula), and sourcemust be attached to your model
  • Be creative – Styrofoam balls are not the only option!

B.Multi-media poster

  • Draw, cut & paste, attach craft materials and/or in some other creative way show the structure of your molecule (an enlarged photo is not acceptable)
  • Label all partson the molecule (NOT a key somewhere else on the poster)
  • Include the picture of the molecule you used to make your creation
  • Include additional information about your molecule, especially how it is important to humans. DO NOT attach the written report - it is a separate part of your grade
  • Use front of poster only. Any work on the back will be discounted.
  • Include additional pictures, if appropriate and helpful

PART 2: SummaryReport of your Molecule and its role (30 points)

Must be typed and in your own words. Include:

  • Name of molecule
  • Type of molecule (carb, lipid, protein, nucleic acid)
  • Basic structure; monomers or polymers, if applicable
  • Picture of molecule and a structural formula, if applicable (see #11-13)
  • Describe or explain biologic functions
  • Foods which contain this molecule (If none, explain where we get it)
  • Importance to humans; find information beyond class notes or text
  • Bibliography in MLA format (TYPE it; do not cut-and-paste from a website)
  • Give me a printout of your written report. Also send a file to Turn it in.
  • Class ID: Period 4 - 7288468 Period 5 - 7288470 Password: biology

PART 3: Oral Presentation (10 points)

Briefly describe your project to the class, showing what you used to represent parts of the molecule. Summarize its significance in living things and especially in humans. DO NOT read the poster/paper or note cards to us. Show that you understand your work.

* PREP WORK: due one week before project, to show that you can manage your time wisely. Includes planning, research, list of sources, the picture you plan to use, a rough outline

May work individually or in teams of two, but understand that BOTH partners get the same grade, regardless of division of labor.
