This lab revolved around the use of a microscope and how it worked. The technique of preparing a wet mount slide was taught and how to label parts of a cell under a microscope. By looking at various substances under the microscope, due to the great magnification, different aspects of the cell were visible
Part A of the lab was merely looking at the letter “e” under the microscope. The next task was to move the “e” left to right then up and down. An interesting observation was that when the “e” was moved left to right, through the microscope lense, it moved right to left and vice versa. This was also true when the “e” was moved up; through the microscope, the “e” moved down and moved up through the microscope when in actuality, it was moved …show more content…
The name for this action taking place was cyclosis or chloroplastic streaming. This happened when the chloroplasts are pushed up against the cell membrane. The reason that they would be pushed was because little things needed to get through and around the cell. Another observation from the lab had to do with stains. The importance of stains were proven in this lab by observing a part of an onion. When looking at the onion through a microscope, initially, only the cell wall, cytoplasm and nucleus was visible. But after staining the onion with iodine, different parts of the onion were visible. Not only was the cell wall, cytoplasm, and nucleus visible, but the starch granules were visible. On top of that the parts of cell were all colored so it was very simple to differentiate. The last observation taken from this lab was the noticeable structural difference between the human red blood cells and the frog red blood cells. The human red blood cells did not contain a nucleus while the frog red blood cells did. From this, it could be inferred that human red blood cells lasted less time compared to the frog red blood

Purpose of the experiment In this experiment, we are assuming an unknown vaporized liquid has ideal gas properties. Based on this we will use the Ideal gas law and stoichiometry to calculate the Molar mass. Based on numeric and qualitative data we might make an assumption as to the identity of the liquid. Materials A special round bottomed flask Aluminum foil Pipette to transfer unknown liquid accurate digital scale A hot water bath setup. Graduated cylinder Ice bath…

heart rate which is measured in beats per minute is the dependent variable. When recording the heart rate, the test subject kept track of their pulse for ten seconds; that number was multiplied by six to calculate the heart rate for 1 minute. This lab will determine how exercise will affect the test subject’s heart rate. Hypothesis: As more seconds are added to the amount of time the test subject needs to perform the exercise, the heart rate will speed up. Materials: - Stopwatch - (3) able…

Molar Mass of Butane Lab Quique Garcia Date of Lab:3/21/14 Introduction The purpose of the lab was to find the molar mass of butane threw an experiment. [1] Butane is a flammable gas found commonly in lighters as an energy source. [2] Molar mass is how much a compound weighs, based on what elements are found in it, and how much of the element is present. If the volume of butane is found then the molar mass becomes possible to find as well. Dimensional analysis will be used in order to…
