Forensics: Mock Crime Scene II
Forensics students at Fontbonne Hall Academy test their investigative skills to solve a crime scene at Cannonball Park.
Blood Lab
Students simulate blood spatter patterns during a Forensic Lab.  Because blood behaves according to certain scientific principles, bloodstain patterns can determine how the blood may have been shed. From what may appear to be a random distribution of bloodstains at a crime scene, students  can categorize the stains by gathering information from spatter patterns, transfers, voids and other marks that assist them in recreating the sequence of events that occurred after bloodshed. This form of physical evidence requires students to recognize and interpret patterns to determine how those patterns were created.
Let It Snow!
9th grade students make artificial snow in their Practical Engineering and Advanced Physical Science class. Insta-Snow* is actually derived from the super absorbent polymer found in baby diapers! This lesson incorporates concepts of Conservation of Mass, Properties of Matter, Metric Measurement & Conversion, and Observation Skills.
The Insta-Snow polymer not only absorbs water but the long chains of molecules swell to an enormous size. The polymer soaks up water using the process of osmosis (water molecules pass through a barrier from one side to the other). When water comes in contact with the polymer, it moves from outside the polymer to the inside and causes it to swell. The polymer chains have an elastic quality, but they can stretch only so far and hold just so much water.
Forensics: Mock Crime Scene
Who killed "Patches" ? Forensics students examine the body of the neighborhood scarecrow at Cannonball Park. The focus of the Mock Crime Scene was to use the principles and techniques of Biology, Chemistry, Physics, Geology, Anthropology and many other sciences in order to solve a mystery. Based on previous laboratory experiences, students solved a crime using their lab skills and knowledge. Suspects included a cow, dog and crow.
Freshmen students are ready to test the strength of their atomic models that they designed and built for their Practical Engineering and Advanced Physical Science class at Fontbonne Hall Academy. The goal was to represent an atom that is held together from materials that resist breakage when dropped from a height of 14 feet. The materials preventing damage would be analogous to the strong nuclear force, and also to a more limited sense, weak nuclear force.
