Who Done Dun It? By:LeeAnn Brager,Bailey Morgan,Jason Nardozza,Kevin Howard,Aaron McDougal.
Fingerprint Comparisons Rubbed lead on a piece of paper. Smeared each finger onto the paper. Then placed each finger to make a print under the right space. After that, we labeled each a loop, arch, or whirl. Then recorded them into the computer.
Powdery Substance We observed different powders such as baking soda, cornstarch, sugar, and salt. Then tested each powder in water. Then in vinegar. Then in iodine.
Teeth Impressions To make our teeth impressions, we each bit into two layers of Styrofoam. Then we compared the bite marks of a piece of chocolate, that someone bit out of, to the Styrofoam. After that we figured out who bit the chocolate.
Foot-To-Height Measured each foot in our group. We wrote it on the paper. We did the math to figure out how tall the person is without measureing.
The Crime When Mrs. King, a science teacher, walked in her room, she found her fish tank broken, and saw her two fish in her sink. Someone had broke into her room! There were footprints of blue paint on the floor. Also, there were samples of powder and fingerprints collected at the scene.
The Criminal It turns out that Dan The Man was the criminal because of all the evidence that was found at the crime scene. The foot print was linked to him because the size of the print matched his height by using our math skills. He always took baking soda with him to get rid of the mothball smell that came from his clothes.(It was also found at the scene.) His teeth matched the imprints from the chocolate found too.
