Double Block

Page 21: Today’s Agenda

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

 

Page 22: Today’s Agenda

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

Homework:2. In Your Notebook: Use the study guide to begin studying for the Carbon Compounds and Enzymes Quiz that we are having on Friday. Identify the top 5 questions you find most difficult, circle them, and respond to them in as much detail as possible! I will check these on Thursday.

Do Now: Find classmates that have the same McMush section that you

reviewed last night for homework. Today’s Objectives:

Develop a set of criteria for guiding high quality scientific writing assignments

Bio 9C: Thursday, 11.12.09Title: McMush Revision

Page 58: Today’s Agenda

Complete the following steps in your notebook. Clearly label the steps. Step 1: Section Calibration

Find classmates that have the same section as you. Compare your notes for your respective evaluations

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.

When completed write these 5 things on the side white boards

The World Famous McMush LabRevision

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.

You DO NOT need to revise the lab if you received 16/20 or higher for the lab report write-up (but you can)
