I am teaching Biology 100 again... an introduction to biology and a reminder of how biology shows up in our daily lives. I lectured yesterday on "The Scientific Method" ...or in other words, "How To Think Like A Scientist". After class, I set up for a lab activity that I was going to run today. I created a fake crime scene for the students to observe, take notes, and then develop hypotheses on what they think happened in the lab across the hall.
There was an outline of a dead body (which I drew around myself laying weird on the floor):
There was a bloody lab coat draped across a chair (I used ketchup) ...
The nearby desk looked like Chemistry gone bad (don't worry, more ketchup):
There was a mysterious black glove pinned underneath an overturned chair (a la OJ Simpson-style):
There was a white powder-substance in a baggy (not cocaine, baking soda!), fake money, a map with a destination on it and a lighter:
There were shoeprints on the floor, running through spilled white powder:
But wait! There's more!! There was a bloody knife (more ketchup):
And a mysterious girl, hiding in the corner (cardboard cutout from an old Hallmark campaign):
All behind police crime scene tape:
The room was locked and untouched by janitors until this afternoon. I took groups of my students to the crime scene room for 5-minute sessions of quiet observation. Some students missed the girl in the corner. Some students missed the bullet casings on the floor (I added those today). Some students were analysing the splatter pattern of blood (a.k.a. ketchup) which was not only on the lab coat and the floor, but I had accidentally squirted on the wall too (oops!). Some students went back a second time to examine the evidence; they were allowed to talk to each other this time.
They compared notes:
These three were FASCINATED by my fake crime scene, running scenario after scenario by each other to explain how the VIC (that's slang for "victim") died. They wanted to know why the silent girl was still in the corner.... I said she was waiting for her lawyer to arrive before she answered any questions:
Krista wanted to know why so many chairs were overturned, was there a fight? Elizabeth wished she had a fingerprint kit and wanted to interrogate the mystery girl. And Trevor was the most curious of them all. He even laid down on the floor to figure out whether the dead body outline was face-down or face up and why were the arms & legs so crazy?
We all agreed that dead bodies slump over in funny ways when falling on the floor...
Long story short... Seriously! Science CAN be FUN!!!
[Note: It took me about 1/2 an hour to pick all of that yellow tape off of the floor, clean up the desks, and scrub dried ketchup off the wall, table and floor. As for the lab coat, I just shoved it in a bag to bleach later. heh heh heh]
