Today’s Objectives: Practice making tables to record data from a lab. Today’s Agenda: Data Tables Pre-Assessment • Review Nucleic Acids • Poster Gallery Walk • Lab Skills Pre-Assessment: Making Data Tables Overview: One important skill in designing and conducting lab experiments is to create a data table that serves as an organized way to collect the data from your experiment. Purpose: To practice making data tables that are both organized and appropriate for a given experiment. This is important preparation for our McMush lab at the end of this week, and will give your biology teachers valuable feedback about how well you are able to accomplish this task on your own. Instructions: Read each experiment description, then draw a data table in the space provided. Today’s Agenda: Data Tables Pre-Assessment • Review Nucleic Acids • Poster Gallery Walk • Nucleic Acids contain C, H, O, N and P Used to store and transmit genetic instructions for making proteins • DNA (stores genetic info) • RNA (carries genetic info to ribosomes) Made of: Nucleotides (monomers) Connected together into long chains (helix) Objectives for Class: 1.

Today’s Objectives: Follow lab safety guidelines and lab procedures Predict which carbon compounds are in a Happy Meal Use chemical indicators to test the compounds in a Happy Meal What are chemical Indicators? 3 Chemical Indicators in this Lab: 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) 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? Note: in Part II you are completing the SAME procedures for Part I, BUT you are using McMush instead of the pure solutions… so for every test, you will test the McMush and the Water 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 McSeating Chart Put on your apron and goggles before starting the lab!
