Example Of Lab Write Up

Example of Lab Write up Microscope Measuring Purpose: To practice measuring small objects underneath a microscope. Hypothesis: My cheek cell will be 25 µm long. Materials: Cheek cells, microscope, microscope slide, cover slip, water, iodine, ruler. Procedures: 1. Place ruler below the objectives on the microscope and measure the field of view under low power in millimeters. Make a sketch of what you see under the ruler under the microscope. 2. Take a toothpick and rub the inside or your cheek with it. 3. Put a drop of water on a microscope slide and then swish the tip of the toothpick around in the water to deposit check cells on the slide. 4. As one drop of iodine to the water to stain the check cells. 5. Place cover slip on slide and then place slide under the objectives on the microscope to view. 6. Make a sketch of the check cells under low power. 7. Find a check cell under high power and sketch this cell as well. 8. Calculate the field of view under high power and figure out how long your cheek cell is. Data: Your sketches should look like this, well not exactly like this, but a sketch version of this, drawn as accurately as you can of course! Notice how round the circles are, you can use something to Trace such a nice circle! Analysis: This is where you will show your calculations for this lab. In other labs you will discuss what your data is telling you. Conclusion: Restate your hypothesis and say whether it is correct or not. You will then discuss what went wrong and what you could have done better.
