AU Biology Microscopes and Micrometers Lab Journal

Microscopes and Micrometers Journal Assignment 20 points possible General Instructions: • All lab journal assignments must be hand-written in your laboratory notebook for this class. Typed journals will receive a grade of zero. • On each page of your journal, you must include your full name and the date in the upper right-hand corner, along with a page number. Journals without this information will receive a grade of zero. • All work submitted must be your own and written in your own words. Journal entries copied from another source will receive a grade of zero. • When you have completed your journal assignment, you will photograph or scan each page and upload those files to the appropriate assignment on Blackboard. All files must be converted to PDF format BEFORE uploading to Blackboard to ensure that the files will be readable on Blackboard (some file types are not accepted by Blackboard). Instructions for how to do this are posted on Blackboard. • Check your uploaded files on Blackboard to make sure that all parts of your assignment are visible and can be easily read. Files that cannot be opened or read easily when viewed will receive a grade of zero. Specific instructions for this journal assignment: For this journal assignment, you will reflect on what you learned in Lab 3, as well as watch a video and answer some questions in preparation for Lab 4. Please turn in the following for this journal assignment: 1. Your lab notebook pages for Lab 3, in which you recorded all notes and observations and made drawings of what you observed under the microscope. 2. Write one or two paragraphs in your lab notebook comparing the different life cycle stages of the fruit fly—egg, larva, pupa, adult. Discuss what you observed about their size differences, morphology (i.e., how each stage looked or appeared), and how best to view each stage using a microscope (i.e., the kind of microscope that worked best for you for each stage, what magnification was best, etc.). This should be based on your own observations and experiences from lab. 3. To prepare for Lab 4, watch this video: https://youtu.be/HXTqaUTGrKg Next, answer the following questions: a. What is an ocular micrometer? b. What does it mean to calibrate the ocular micrometer? c. Why is calibration necessary? d. How do you calibrate the ocular micrometer in a microscope? e. What would be the measurement of a specimen with a length of 2 OU when the calibrated measurement of that ocular reticle is 1 OU = 120 µm?
