Lab 1: Measurement and Microscopy Essay

1. Fill the graduated cylinder nearly to the top with water, with a tall glass tube open at both ends (the water level with act as the closed end).

Preparing specimen for electron microscope hard, light microscope still very useful as a window on living cells.

1) Apply the stain to your first unknown slide and examine it under the microscope.

This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.

The illuminating parts of a microscope enable us to see the detail of the subject placed under the microscope. The three main parts that enable us to do this are: the condenser which illuminates the object that is placed under the microscope, the objectives which forms the magnified image, and the eyepiece which enables us to see the magnified

5 Remaining in the darkroom move print to tray of running water, do 30-45 second rinse. Squeegee print, place on flat tray.

Again, after ten seconds, the slide was rinsed with distilled water to wash off the decolorizer. The slide was placed back on the staining rack. Approximately ten drops of safranin were covered on the slide allowing resting for one minute. After one minute, the slide was rinsed one final time on the small sink followed by blotting the stained slide with Bibulous paper. The slide was placed between pages of Bibulous paper to help

3.Secure the other end of the tube into the hole located on the rubber stopper

The investigator will examine duct tape piece “A” against duct tape pieces “B”, “C”, and “D” to determine similarities and differences between them utilizing increasingly strong microscopy methods—beginning with the unaided eye, then utilizing a magnifying glass, and ultimately a stereomicroscope. While using each of the above methods, the investigator will carefully note observations made with each in his or her lab notebook. These observations will come in the

Dispense .5 mL water into the already weighed conical vial, replace cap and face insert on its down side.

Submerge the graduated cylinder in the plastic tub so that it is completely filled with water. Hold the open end of the graduated cylinder and move it vertically upside-down where the open end of the graduated cylinder is still submerged in the plastic tub. Clamp the graduated cylinder the ring stand of the lab table to keep it in place. perforate a hole in the top of the rubber cork for the solution container. Cut a straw the length of about four inches. place the straw inside of the rubber cork hole. Set up your timer for two minutes.

5. Wet the paper with distilled water to hold it in place in the funnel. Transfer all the solution and the precipitate from the beaker using a rubber policeman. Wash the precipitate with two or three 5-mL portions of distilled water. Do this by adding each portion to the beaker in which you did the precipitation to transfer any remaining

The materials used for the first part of the experiment comprised of the following: a microscope, 4 slides, 4 slide covers, blood samples, lancet, a sheet of paper towel, 3 test tube droppers, Solutions A, Solutions B, and Solution C.

Purpose: Being able to learn how to correctly use a microscope and the oil immersion lens to be able to see the prepared slides. Also to learn how to prepare my own yogurt and blood slides.

Some are so large that they are housed in silos several stories high while others are small enough to fit in the palm of a hand. These instruments have given scientists a new look at the world around us.
