What was you favorite activity/topic this year? Why was it a favorite?What was your least favorite? Why?If you could change one thing (Not the amount of homework) what would it be and how would you change it?

                   My favorite activity in class is doing labs. All the labs that we did were very exiting and interesting. Learning something is fun but when your actually experimenting something u learned before, that is exiting! Any labs that we did taught me many things and they were all very fun and interesting. My least favorite activity is the karoke project. We had to create our own song about biology and sing it in front of the entire class. This was the worst project i ever got because my group and i cant sing at all. Well we can sing but we sing horribly. If I could change one thing i would change the karoke project to something else like a writing project. Instead of singing a song we could write about what we learned in biology. This would be easier for me because writing a few paragraphs is easy compared to singing a song in front of your class. I would tell our teacher Ms.Malonek that a karoke project would be a bad idea because above all most people are better at writing then singing a song.

Blog#13 How has DNA changed how we investigate crimes? What are the two main tests? Describe them

DNA has helped people solved crimes more faster and easier. Such as a strand of hair left behind at a crime scene can be used for DNA testing to find out who the strand of hair belongs to. The two main tests are RFLP and PCR testing. RFLP testing requires larger amount of DNA and the DNA must be undegraded. Crime-scene evidence that is old or that is present in small amounts are often unsuitable for RFLP testing. PCR testing often require less DNA than RFLP testing and the DNA may be partially degraded. PCR tests are also extremely sensitive to contaminating DNA at a crime scene and within the test laboratory. PCR is less direct and somewhat more prone to error than RFLP. However, PCR has tended to replace RFLP in forensic testing primarily because PCR based tests are faster and more sensitive.
