Today’s Agenda Science Starter Organic Compounds Lab Lab Discussion Quiz Return Exit Quiz/Homework

Egbert's Stomach Today we will be finishing our discussions of organic molecules and chemistry The goal of this lab will be to identify the contents of Egbert’s stomach using various solutions Important to consider positive vs. negative results Consider why these reactions are taking place

Materials At your Station: Egbert’s stomach contents 4 test tubes Test tube rack Gloves Goggles Brown Paper Beakers Glass Dropper At Front: Biuret Solution Benedict’s Solution Iodine Paper Towels

Want to check your work?? OR you can google “occc biology labs organic compounds” and click on first link

CARBOHYDRATES TEST FOR SUGARS = BENEDICT’S REAGENT POSITIVE TEST RESULT: BROWN SOLUTION

CARBOHYDRATES TEST FOR STARCHES (CARBOHYDRATES) = IODINE POSITIVE TEST RESULT: PURPLE/BLACK SOLUTION

LIPIDS TEST FOR LIPIDS = SUDAN IV OR BROWN PAPER BAG POSITIVE TEST RESULT: RED SOLUTION

PROTEINS TEST FOR PROTEINS = BIURET’S REAGENT POSITIVE TEST RESULT: PURPLE SOLUTION

Egbert Lab Discussion How do we know if a certain organic molecule was present? What are the contents of Egbert’s stomach? What is the point of this lab?

Organic Molecules Quiz Quiz score should be at top right Look at the questions you missed with your notes, make sure you understand these basic concepts!! If you are struggling with this content, please stay after school this week (tomorrow or Thursday) Remember that quiz grades are now informal, so do your homework!!

Exit Quiz & Homework For homework complete your lab report and turn in tomorrow (white sheet and separate sheet with answers) For exit quiz take out a piece of paper, pencil, and put everything else away!!

Exit Quiz What organic molecule are starches/sugars? What is the role of protein in the body? What is the role of fat in the body?
