Blood spatter

The girls just finished a really fun forensics class. Here are some pics from their lessons on blood spatter anbd a pic of the shoe mold they took. If you want to learn more, there are good pictures and tutorial information at: http://www.bloodspatter.com/BPATutorial.htm .

Forensics

This week we sorted through this trash with some friends to figure out who a crime suspect was. It was messy, but fun!

Fun Science

We just participated in a seed germination experiment entitled Tomatosphere. We planted two sets of seeds and recorded germination data for both. One set had been in space conditions and the other was the control set. We were not told which was which. At the end, we turned in our data to the Tomatosphere website and found out what results other classrooms had and which seeds had been in simjulated space conditions. Our experiment found that 100% of the seeds in spacelike conditions germinated and only 75% of the control seeds germinated.

We also just participated in a Forensic Science class. We learned how to differentiate between cat, dog and animal hair. We learned how to get fingerprints from surfaces and how to use traditional fingerprinting. We learned how to identify human blood. We learned how to use a mold to save a footprint marking. Finally, we learned how to analyze handwriting samples.
