Grab Your Popcorn! It's Crime Lab 2013 Movie Time!

I have never enjoyed grading as much as I did while viewing the movies created by my students for our crime lab. Here are the main lessons I learned from this project to remember for next year.

1. Only allow students to use first names in projects. I will not post anything on here that has a last name. That definitely limits me on the number of videos I can show you.

2. You can never have enough bandwidth when uploading projects. Thank goodness I was on spring break the week after projects were due. I was able to focus on getting the projects uploaded to Vimeo when no one else was on our network. Even at that, I averaged 10 minutes per iPad movie.

3. Check weekly limits for free video uploading so you don't have to pay.  Because I did not want to spend money when uploading videos, I could only upload about 20 movies a week. I was lucky to have my weekly limit reset on Tuesdays to get them all done.

4. Providing an iMovie tutorial is extremely helpful to keep frustration at a minimum.  Students were at different levels of comfort with the app so I made sure I was available to help learn the quirks with them and share anything learned from other students as the days progressed. There are some fabulous YouTube tutorials out there!

5. Be patient and prepared for failure. In anything new, especially technology minded, I have learned that what I think will take 20 minutes may take an hour. However, I have learned more from those failures than anything that goes right the first time through.

6. Be ready to have your socks knocked off! I am still marveled by my students. I am one proud "school mom"!

Grab your popcorn and enjoy the shows!

Suspects and Crime tape and iPads, Oh My!

My students are currently finalizing their Crime Lab 2013 projects. This three week unit is what pushed me to start this blog. I was posting pictures and updates on Twitter, and actually had requests to blog about the project! So here goes!




I started doing a forensic science unit 12 years ago. It started with two suspects and four classes of students. It has now evolved into having 137 biology students divided into investigation teams (one per suspect), 42 faculty suspects and one faculty victim. My colleague, Scott Fowler, and I co-teach the unit for three weeks. It is fantastic to have flexibility in our schedules to work and collaborate as we do. It is also wonderful to have the opportunity to interact with every single 9th grade student in our school. This year's major change: an iPad is assigned to each team for the duration of the project.



The apps that have been most critical for this project are Explain Everything, Dropbox, Google Drive, and iMovie. This is also the point to recognize Ed Patterson, our Director of Academic Technology. He has been our "go to guy" for all questions iPad. He is patient with my questions, and flexible to meet and work with students. Having solid academic tech support is essential.

First, students are introduced to evidence collection by Joan Turner, City of Suffolk Education Outreach Coordinator, and chain of custody by Matthew Glassman, a Deputy Commonwealth's Attorney in Suffolk, Virginia.  Walking students through a case prior to their assignment has proven to be very helpful.













Students navigate through the project by completing a series of tasks and labs that narrow the suspect list from 42, to 10, to 4 to the top two suspects. DNA profiling reveals the guilty suspect. The highlighted activities include hair analysis, fingerprint analysis, blood spatter pattern, drug analysis, karyotype analysis, blood typing and DNA profiling. Three key points of any good evidence collector are photos, notes and sketches. As teams progress through the lab, they are able to do all of this in one organized location....the iPad.

Bottom line, iPads shouldn't ever replace collaboration, conversation, reading, writing, and data analysis. Students need to interact with each other. 

Stay tuned for the forensic teams' iMovie "Mockumentaries" that are due by Friday this week!
