In our science class we had a special quest speaker, Detective Brocky (former detective) who spoke to us about crime scenes and what to look for in terms of evidence. The presentation was very informative. I learned there are three types of fingerprints, not the feature, but how fingerprints can occur. There are latent, patent, and plastic fingerprints. Also a person cannot determine the age of a fingerprint unless physically present witnessing. To find a fingerprint using powder is the oldest and least sophisticate method, but still good.
An interesting fact I learned from the Crime scene and Contamination power point was how 99.9% of human DNA is the same for everyone; therefore, only 0.10% makes you unique. WOW! Also I knew we were similar to chimpanzees, but we have 99% of DNA the same as them. Double WOW!
Later in the day, after the presentation, students from Block 3 presented a Project Learning Tree Lesson. It was about keeping our planet clean and the types of pollutants we create. It was a very well done lesson, and I really liked the incorporation of the video, crime scene (wanted) idea.
After that we went to do small activities in the PAC where we did a fingerprint lab and a hair evidence lab using the proscopes. It was really cool seeing your hair with the proscope and comparing it to a classmate whose hair is a different color.

Overall it was a fun, exciting, informative and busy class. :)
