Improvements Needed Post “Safety Lab”

Improvements Needed Post “Safety Lab”. Most students lost points from the “General Record-Keeping Procedures” section. Better titles are needed: The title should describe the goal of the experiment. “Safety Lab” does not describe the entire goals of the lab

Presentation Transcript

  1. Improvements Needed Post “Safety Lab” • Most students lost points from the “General Record-Keeping Procedures” section. • Better titles are needed: • The title should describe the goal of the experiment. • “Safety Lab” does not describe the entire goals of the lab • Make sure to read the entire procedure before starting your experiment. • Reminders: • Biotechnology History Presentation is due on Friday • A copy must be e-mailed to myoung@csisd.org • Turn in your homework “Biotech Boom…”

  2. Cheese Production: The Evolution of Cheese-Making Technology

  3. This to change from the manual: • Hypothesis – Come up with your own hypothesis & make sure to include all of the curdling agents in your hypothesis. • Chymosin is currently unavailable, but hopefully will be available tomorrow or Friday. Leave space in your notebook to include this curdling agent • Procedures Step #2: • Each group will be testing all for curdling agents, not a single agent assigned by Mr. Young. • Make sure you label your tube by writing on a piece of tape, not of the tube itself. • Step #3: Use the Vortex instead of shaking the conical tube by hand. • You will stop after Step #5 today & will continue the lab after 24 hours. • Data Analysis: you should generate an excel spread sheet that will be glued into your lab notebook. Hand-drawn graphs will not be accepted • Witnessing will be done by Mr. Young

  4. 09/05/2013 • Chymosin is now available & can be found in a test tube on the labeled test tube racks • Gloves & eye protection (your prescription glasses will work) are required for this lab • Complete your initial 15 minute incubation (checking your samples according to the lab manual), and return them to the conical tube racks for a 24 hour incubation at 37 °C. • Your remaining time will be for you to work on your Biotech History Presentation (due tomorrow!) • We will meet in the lab again tomorrow. • Don’t wait for Mr. Young to tell you to get started, get to work!

  5. 09/06/2013 • Ignore the question posed in Step #8 • Once your completed your data collection, post your results on the white board in the lab. • Take a picture of the class data before you leave today so that you can include a class average for all the data points & generate an additional graph in your Data Analysis Section. • Your excel graphs must be glued or taped into your lab notebook & if you need me to print your graph please e-mail me a copy of it over the weekend (myoung@csisd.org) • Review “Writing an effective experiment conclusion” that was handed out on the first day of class. This will also be available online at consolaquatic.com, under the most recent Biotech post. • Keep my scales CLEAN! • Don’t wait for Mr. Young to tell you to get started, get to work!

  6. Writing and Effective Experiment Conclusion • 3 Parts: REE, PE, PA • REE: results with evidence and explanation • Answer the purpose question • Give data to support your answer • Explain support or refute for the hypothesis • PE: possible errors • Experimental error (do not include things such as measuring wrong or calculation wrong) • Good error: something inherent in the experiment that may not be as efficient as possible • Give recommendations to improve the experiment, ways to fix the error

  7. Writing and Effective Experiment Conclusion • PA: practical application • What is an application of the experiment? • How are the finding valuable?
