Since Criminal Minds and Law Order compose about 70% of my DVR recording list, you can imagine my excitement when I heard that we were going to have a guest Lieutenant speak to us about Crime Scene Investigation and Forensic Sciences in regards to Fingerprinting. The Lieutenant taught us how fingerprints are the oldest accurate form of identification and different characteristics and types of fingerprints:
Types of Fingerprints
Patent- readily visible (liquid)
Plastic- to mold or to form (putty, clay, wax, soap)
Latent- hidden or concealed (must be developed or enhanced)
Fingerprint Patterns
Circular
Loop
Arch
Characteristics
Enclosure, Dot, Ridge Ending, Bifarcation
We also learned about DNA (simple DNA kit includes distilled water and cotton swabs!) and the CODIS system (COmbined DNA Index System). I am very excited to incorporate some type of Crime Scene Investigation theme into my classroom with this new information! Block 3 even gave a great presentation that modeled one creative way to incorporate CSI and civic responsibility into the classroom with a pollution investigation.
After the presentation, we split up into our Blocks again and were able to participate in different experiments ranging from honing in on our investigation skills with clay to utilizing ProScope technology to investigate our clothing and hair particles. We had a great time investigating and experimenting with salt, sugar, baking powder, and iodine while surrounded by our RainForest Mural we created, along with multiple other blocks. My contribution to the mural was a leaf cutter ant.
