Fingerprinting Virus DNA

First, we had to centrifuge the DNA for a better concentration. Then, we injected each virus into the gel casting tray after we put it in the solution. The point of the experiment is to determine what virus the unknown is. So far 3 viruses have affected Pennsylvania. Alabama, and Missouri.

DNA Extraction

We are using sterile water and protease to extract DNA. We scraped our cheeks with our teeth for 1 minute, then used the sterile water to swish it in our mouth for another minute. We inverted the tube, and saw chunks of something in the tube when the solution was added. Next we added protease and added it to the water bath for 10 minutes. This is my DNA.

Reproductive Organs Lab

We got a lesson in this lab of how cells become babies. Pretty interesting.

Photosynthesis and Chromatography Lab

In this lab, we tested leaves for photosynthesis. We also used the chromatography paper to show beta-carotene, xanthophylls, chlorophyll a, and chlorophyll b. it also revealed that plants repeal green light and grow better in white light.

Human Genetics

Today, we learned about recessive and dominant genes. We determined what traits we have, such as straight hairline, bent little finger etc.

Osmosis/Diffussion Lab

Cells Lab

In this lab, we traced and colored different types of cells, including animal cells, bacteria, mitochondrion, and plant cells. The purpose of this lab was to recognize what things where what and its function.

Microscope Lab

This lab was really fun. We learned how to use a microscope the proper way. We learned how to adjust the lighting, zoom in and put and other various things about the microscope. The picture with the purple slide was tested for cheek cells. We used a toothpick to swab the inside of our mouth, an used purple due. We put it under the microscope and saw cells. Some people we about to see stuff swimming (sadly I was one of those people.) the second picture is a single hair strand. I used my arm hair. The picture isn't a good one, but I was about to see some muscle that was pulled from my arm.

Graphs Lab

In this lab, we learned the correct procedures for how to make an accurate graph. The first graph (bar graph) is the length of fingers graph. The second graph is how we determine the unknown. The third graph shows how to have the best fit when you have multiple points. It helps to show a relationship between the points.
