An Iquiry Lesson

For the past two years my Jr. High science department has implemented an inquiry based lab activity that involves the use of forensic science techniques.  We noticed an interest in our students with the growing popularity of crime scene investigative television shows.  Always on the lookout for new exciting ways to conduct labs and present objectives we, as a department, decided to adopt theses teaching methods to incite interest in the inquiry process.  How better to understand the importance of following procedure steps then to use them to solve a crime. 

Prior to the crime being committed the students spend time reviewing a variety of  power points over things like evidence collection, finger printing, hair analysis to name just a few.  During these presentations discussions are held in regard to how our investigation will benefit from having prior knowledge of procedure steps to follow when investigating a crime.  The students prepare by looking at sample crime cases which contain the investigators notes.  The students are given paperwork that will help them document their steps in solving the crime.  These pre-crime preparations create interest and partnership among the students as they plan responsibilities for the group members. 

On the day the crime is committed students set their action plan into motion.  Each student is responsible for a required task at the crime scene.  They gather evidence, measure the area, sketch the scene, and take pictures.  Over the course of the week students interview predetermined suspects, share findings and document information gathered.  They also complete a series of labs that represent evidence testing in a crime lab.  Each day a case finding/fact is released to the student investigators to help them as they coordinate the information they have gathered.  The released information helps the students stay on track during the investigation.

The students keep a daily journal entry of their groups’ findings. They systematically record all evidence as they follow procedure and create a timeline for the crime.  They utilize witness information as well as collected evidence from the crime scene.  By allowing students to choose the jobs they have the most interest in we can differentiate the learning experience for each student.  Giving students the opportunity to choose how they learn the objectives allows them to be vested in the information they are learning.  Flexible management of classroom resources enables students to work in ways with tasks that maximize their learning (Marzano, 2010).  There has been much emphasis put on authentic assessments and differentiated instruction in the classroom. Teachers are able to determine student ability through performance tasks; the crime scene investigation allows the students to exhibit their knowledge in a manner that best suits their individual learning style.  My students were able to performance the tasks and activities which in turn displayed their understanding of the objectives.  These types of activities are designed to ensure student mastery, internalization, and understanding of the objective (Marzano, 2010). 
I spend much of my free time looking at ways to differentiate my lessons and include authentic assessment into my curriculum.  I know this is a benefit to my students and have watched as they take ownership of their education when allowed to choose how they learn.  I spend much of my time familiarizing myself with strategies that work for my diverse learners. In doing this I must also keep in mind that as a science teacher it is my responsibility to teach the actual science content and incorporate culture and other interests, but first and foremost keep the content intact (Buxton & Provenzo, 2011).
