Product information "Forensic Chemistry Experiments - Print and E-Book"
Each of the 15 experiments in this book kicks off with a case study designed to engage high-school and college-level chemistry students. Immerse them in the excitement of solving crimes through hands-on experimentation using Vernier sensors such as pH, pressure, conductivity, and temperature to investigate complex questions involving forensics. Students explore gas pressure through a failed bottle rocket launch, Beer’s law through a case of poisoned wine, and even more through engaging forensics investigations.

Starting with the 2013–2014 school year, the AP Chemistry Course Description recommended labs have been reduced from 22 to 16 and at least six of the 16 experiments should be an inquiry-based model of instruction. Advanced Chemistry with Vernier provides a variety of experiments for the additional 10 non-inquiry experiments.
Use it in addition to Vernier Chemistry Investigations for Use with AP Chemistry (APCHEM) for a comprehensive set of topics.
Forensics with Vernier (EN) - INAKTIV
CHF 65.00*
Forensics with Vernier is for teachers at the high school level who wish to introduce their students to forensics using engaging and realistic laboratory activities with Vernier probeware.
Containing lab activities dealing with various aspects of forensic science, each lab is preceded by a short scenario that introduces the concepts or methods to be addressed in the lab. These introductory sequences are designed to “hook” the students and show them situations that require various forensic techniques. The Case Analysis questions for each activity relate to the concepts and techniques addressed in the lab, and many require the students to “solve” the crime introduced in the scenario with the data they collect.
Forensics with Vernier has printed student instructions for computer data collection with LabQuest App and EasyData instructions on the accompanying CD.
Food Chemistry Experiments
From
CHF 64.80*
