We brainstormed about what we already knew about forensic science, and we learned more about what forensic scientists do. Older students began to understand the relationship of chemistry, physics and biology in forensic science, and we discussed physical evidence used, such as fingerprints, hair samples, and blood.
In week #2, we used our iPads to really do some investigating. Younger students had a blast on an app called "Cupcake Detective". They had to follow clues closely to create a cupcake (batter type, frosting, fillings, etc.) to solve a mystery. It was difficult for some because the clues weren't all that easy. All squealed with delight when the mystery was solved!
Older students attempted to sketch the STEM Lab from memory--showing them the importance of good record keeping and photographs when investigating. Most remembered about 15 - 20 items in the lab. When faced with the challenge of finding some missing items from the lab, all agreed our memory is not the best source for recording important evidence. Grades 3 - 6 used the technology of the iPad to solve "The Case of the Barefoot Burgular". Lab groups used clues and forensic techniques to determine which suspect broke into and vandalized a school classroom. Students had to compare physical evidence, such as fingerprints, to determine that indeed it was "Dan the Man," who committed the crime.
It was a great study of a part of science that few students really knew much about! The "Cupcake Detective" app is available on iPhone, iPad, and iPod. The link to "The Case of the Barefoot Burgular" can be found at:
