Overview
Hello!! There are two parts to this assignment! Please complete and fill out everything in the attached document lab experiment worksheet. The second part is to complete a lab notebook entry which i included all the directions for it under step 4! For the worksheet please fill it out on the worksheet not on a separate piece of paper, for the notebook entry that can be in a different word document. Thank you!
Complete the Periodic Trend lab experiment worksheet. Submit the completed lab worksheet here. Also, record your overall results in the lab notebook and submit to the notebook to the associated assignment
Step 1: Download the Periodic Trends lab worksheet
Step 2: Follow the instructions provided to complete the lab worksheet and answer all questions.
Step 3: Submit completed worksheets.
Step 4: Submit lab notebook for Module 4B: Lab Notebook Entry.
-Instructions for Lab Notebook Entry:
Introduction/goals – should be what we’re doing and WHY?
- Why are we doing this exercise?
- What does doing this exercise tell us about the organisms, the water sample, the environment, etc.?
- Example: Bacitracin Susceptibility Test (this is ONLY an EXAMPLE)
“The purpose of the bacitracin susceptibility test is to presumptively identify β-hemolytic group A Streptococci from other β-hemolytic Streptococci. It also can differentiate between Staphylococci and Micrococcus and/or Stomatococcus. The test relies on the use of the antibiotic bacitracin, which inhibits cell wall synthesis in growing cells. Therefore the antibiotic would inhibit the growth of susceptible cells. We will swab plates with different organisms and place a disk infused with the antibiotic bacitracin on top. We are looking for inhibition of growth around the disk. A zone around the disk of 10 mm or greater would be interpreted as susceptible.
