This lesson is being designed for students taking chemistry. Most students completing this lesson will be 11th graders but a few are in 10th or 12th grade. Students will be required to add activities from this lesson to a “Forensic Science” ThingLink created during an earlier lesson. The majority of this lesson will be completed almost entirely online. We will watch the video The Poisioner’s Handbook together as a class but the remainder of the lesson will be completed online. After viewing the video, students will write a reflection about the movie using the Schoology discussion forum. Next, students will create a Piktochart timeline of important events in forensic science. Finally, students will complete the interactive Poisioner’s Handbook labs to see the history of how forensic science is used to solve crimes. Students will add their findings to their ThingLink created in a previous class.
- The main Content (C) of this lesson is the history of forensic chemistry and forensic chemistry laboratory techniques
- The main Pedagogy (P) this lesson is project based learning and inquiry based learning. There is also a group discussion piece where students will have opportunities to share ideas.
- The main Technology (T) of this lesson includes a projector or computer to view the movie and computers for ThingLink, Piktochart, and Poisioner’s Handbook timeline and interactive labs.
Pedagogical Content Knowledge (PCK)
Describe: Forensic chemistry is not an area of science that many students have not yet been exposed to in an educational setting. For the timeline part of the lesson, project based pedagogy would work well because the learning goal for students is to summarize important dates in forensic science. Representing these in a visual manner is helpful because timelines allow students to connect to prior knowledge and see relationships between events. Inquiry-based learning is useful for this content because forensic science is all about looking for information to solve crimes. Students will be acting like forensic chemists as they work through the virtual labs.
Support: “Timelines provide a visual aid for identifying cause and effect relationships between events, and a visual prompt to activate student prior knowledge” (Fillpot, n.d.). Also, the sample TPACK lesson on Cell Structure and Function talked about the relationship between inquiry based learning and increases in science SAT scores.
Technological Content Knowledge (TCK)
Describe: Viewing the video will introduce students to the history of forensic chemistry. This video will allow students to activate prior knowledge and spark curiosity about forensic chemistry topics. After watching the video, students will be able to reflect on the information that they viewed. During their discussions with classmates, students will begin to develop questions, ideas, and interests regarding certain concepts from the video. Next, students will use information from the video and online timeline to apply it in an interactive way. Creating the Piktochart will allow students to transfer data from the video and the timeline to their own creation using a technological tool. While doing this, students will be summarizing key information about the important dates in the field of forensic chemistry. Lastly, the virtual labs will enable students to perform the forensic chemistry tests that they have seen in the movie and read about in the timeline.
Support: In recent years, Inquiry-Based Science Education (IBSE) has proved its efficacy in education by expanding on “traditional” lessons and motivating students to actively participate in science (Rocard, 2007)
Technological Pedagogical Knowledge (TPK)
Describe: Students will be using Piktochart to create timelines. I have never used Piktochart before but we learned about it in a training session. It has been suggested by Piktochart’s webpage that simultaneous processing of images is much faster than processing of text. The virtual labs are a great way to show students the process of the lab quickly, safely, and at their own pace.
Support: “As images are processed simultaneously, we process them 60,000 times faster than we process text” (“Using Infographics,” 2016)
Scientix Blog – There are many benefits of using virtual labs in science that can be found on the Scientix Blog.
Technological Pedagogical Content Knowledge (TPACK)
Describe: The elements of this lesson were chosen to meet the goals of fostering meaningful student learning during a time when students are in and out of class due to testing. This lesson is meant to be an exploratory unit on forensic science, so the flexibility with information learned by students allows for an easy transition to online learning. The interactive nature of the lesson allows students to have ownership of their learning process.
