Zoom in…
A Single Organelle (chloroplast) in the CellPLANT CELLS
A Single Molecule inside the Organelle (chlorophyll)
Atoms come together to make up molecules
Zoom in a lot more…
What elements do you see in the atoms that make up this molecule?

More versatile than any other element! Can bond with itself and many other elements Forms millions of large molecules
Monomer – a single, building-block molecule based on carbon
Polymer (a.k.a. Macromolecule)– “Many monomers” a long chain of monomers bonded together to form one huge molecule
Objectives for Class: Identify the 6 key elements found in living things Explain how monomers and polymers relate to each other Identify examples of foods that contain carbohydrates Identify two key functions of carbohydrates in food
4 Types of Carbon-Based Compounds:
Carbon combines with Hydrogen, Nitrogen, Oxygen, Phosphorus, and Sulfur to form these 4 Compounds:
Carbohydrates Lipids Proteins Nucleic Acids
Each type is made of monomers that connect to form polymers.
IMPORTANT NOTE: Each type is separate – not made of each other! Lipids are not made of carbs!]Objectives for Class:

Bio 9C: Thursday, 10.22.09Title: The McMush Lab
Double Block
The World Famous McMush Lab… Important Terms and Concepts I
What are chemical Indicators? Chemicals that indicate the presence of a certain substance by changing color when
they are in contact with that substance. A change in color = Positive Result (the substance is there) NO change in color = Negative Result (the substance is NOT there)
3 Chemical Indicators in this Lab: Benedicts Solution: Changes color when it comes in contact with a Monosaccharide
like Glucose Iodine: Changes color when it comes in contact with a Polysaccharide like Starch Buiret Solution: Changes color when it comes in contact with a Protein
Negative Control = Water The variable that is the same for all test trials. It is guaranteed to give a Negative
Result Why use water?
Why must we do Part I BEFORE Part II? What does Part I tell us so that we can do Part II?
Procedural Notes: Each team member should be the leader for 2 of the 4 tests When using the Hot Plate and Boiling the water - NO Messing Around
The World Famous McMush Lab… Important Terms and Concepts II
Using the well plate for the protein and starch tests Use 2 wells for the Protein Test
(one for the pure protein, the other for Water) Use 2 wells for the Protein Test
(one for the Starch, the other for Water)Protein Solution + Biuret Indicator
Water in Protein Test + Biuret Indicator
Starch Solution + Iodine IndicatorWater in Protein Test + Iodine Indicator

Which response is stronger and why? Compare your notes of the 3 qualities that make it stronger –
compile your list and narrow the criteria to less than 5 qualities that make the stronger selection a better choice
Step 2: Lab Report Jigsaw Form groups with classmates who have the three other sections Compare the criteria of good scientific writing your last groups
came up with. Use a table to compare the criteria different groups developed so
that one side shows the similarities and the other shows the differences.
Use this analysis to compile a list of at lease 5 qualities that make scientific writing strong.

Peer Revision:1. Swap your McMush Lab Report with another
student in your group. 2. Use the 5 Criteria we have just developed
to evaluate your neighbor’s paper. Next to each section of the paper (Intro, Methods,
Results, Discussion) write and circle the number of the criteria ( i.e.: 4 ) that is either missing from the section and/or can be improved.
