CSI Workshop Set Up
Mystery Powder StationMystery powder station had the following set up. The kids were given a “mystery powder” from the crime scene, and 6 other labeled white powders – baking soda, salt, flour, cornstarch, sugar, and, I think, crushed chalk. They were also told that each suspect had access to different combinations of two out of six powders, and they were listed in their printout. The station had water and vinegar available, and the kids had to identify a mystery powder by observing its reaction to water and vinegar in comparison to known substances. Of course, the mystery powder turned out to be baking soda, and Smarty zeroed in on this possibility right away, since we did a similar “mystery substance” experiment once at home.
Thread Burning StationSmarty thought that thread burning station was the coolest, since she does not get to burn stuff at home often enough. Sadly, I didn’t take pictures from this station because it was so crowded. It was also the most difficult station, because the kids were given again labeled threads (wood, acrylic, cotton, and silk) and were asked to observe how they burn and how their ash looks like in comparison to a mystery thread. Of course, they were given tongs to hold their threads over alcohol lab burners and protective eye gear for all stations.
DIY CSI WorkshopMy friend Phyllis at All Things Beautiful has a detailed plan for a thorough multi-week DIY Criminal Science workshop that she ran for her homeschool co-op:
- Setting Up a Forensic Science Class Crime Scene
- Breaking Down the Crime Scene
- Ink Chromatography and Fingerprints
- Iodine and Baking Soda Labs
- Solving the Mystery
