I’ll take care of drawing part
It doesn’t have to be drawn it can be a printout
Example Lab – Detailed Instructions for Each SectionAPA Formatting: Set margins at 1“on all four sides. Use Times New Roman font size 12Title:The title of the lab will be provided to you.Purpose: Write the purpose of the lab in your own words – if you aren’t sure, make an educated guess. Think about what’s being testing and why.Hypothesis: Make an educated, intelligent guess about the expected outcomes and choose only one result to give, unless many results are the case. For example, for a gram stain, you could be 1) positive or negative, but you can also have 2) a variety of shapes and 3) arrangements… so you will have 3 answers here instead of one…but don’t pick all options. You may use the book/internet to help you pick a good hypothesis. Also make sure to explain your logic (why you made that guess). Remember, you are predicting what your results will be, so explain why you made the hypothesis you did. Don’t use either/or answers and be specific. Choose one result for each outcome. If you are incorrect, that is fine, simply reject your hypothesis. Example:Good hypothesis: ?I expect my sample to be gram + with a cocci shape and staphylococci arrangement because Staphylococcus species are some of the most common bacteria.” (Note: You may not use this example).Bad hypothesis: ?I believe that I will be able to determine whether my sample is gram + or gram – by the end of the experiment. (too general)?I believe my sample will be gram +. (doesn’t cover all outcomes)?I hypothesize that I will understand the gram staining process by the end of the lab. (doesn’t directly relate to any of the results of the experiment)Introduction: Provide background information and introduce the reader to key aspects of the lab. For example, discuss the history or key features of the procedure. Make sure to answer all of the questions in your intro (please write the answers as part of a flowing paragraph, don’t just give the answers or write as question/answer). You may use any source, other than another student to come up with these answers. Keep in mind, you will be tested over this information so make sure you completely and correctly answer the questions. Please use in-text citations (throughout the paragraph) and a reference list (at the end of the lab) for all information you used to create this section. (use APA format to generate the in-text citation and reference list). ONLY the in-text citations and the reference list need to be in APA format.Methods: Materials list: List all of the equipment you need to complete the lab. This includes the materials list provided in the lab instructions AND any other supplies that you might need to complete the experiment. Be specific. You will see all equipment used when viewing the video… take notes as you go.Procedure: Step-by-step procedure on how to complete the lab. Include ALL steps (even if you think it’s obvious). State exactly what you would do from beginning to end. The goal is for your parents/siblings/children/some random person off the street to be able to complete your entire experiment using only your procedure.
Lab 1: Introduction to the Microscope and Oil ImmersionSLO 1 – Demonstrate skills of microscopyPurpose: You will determine this. Why are you performing this lab?Hypothesis: You will come up with this (you are predicting what your results will be)Introduction Questions:1. What makes a light microscope compound?2. What types of lenses does a compound microscope have?3. Because it contains its own light source in the base, a compound light microscope is also known as a ____ field microscope because specimens are lit from below and viewed from above.4. How do bright field and dark field illumination differ?5. How do you determine the total magnification of an image with a compound microscope? Give an example.6. What is the typical magnification of the eyepiece in a compound microscope?7. What are the typical magnifications of the objective lenses in a compound microscope? 8. What is the difference between magnification and resolution (resolving power)?9. Why do you need good resolution when viewing specimens?10. As resolution increases, does wavelength increase or decrease?11. What is the “working distance”? Does this increase or decrease as magnification increases?12. What are some precautions for working with the oil immersion lens?Methods:Use what you learned in the video to write up the materials and methods for observing a prepared slide. Results:You can simply mention you have successfully learned how to use a microscope and complete the oil immersion technique. Conclusions:RERUN method (see instructions)-Uncertainties:Q.What would you see in the microscope if you forgot to bring the stage all the way up? What is the importance of bringing the stage all the way up?-New:Q. Using Figure 3.12. see below – Draw (to the best of your ability) the compound microscope. Label each structure given and give a brief explanation of that structures function. You can take a pic of your drawing and answers and upload that pic with the assignment.
