Last year about this time I wrote: Man vs. Chicken: A Battle in the Name of Science describing a laboratory investigation into the different types of fractures using chicken bones. As most teachers, from year-to-year I create new activities, get rid of the flops and tweak those that have been successful in the past. That’s just what I did with this investigation.
There were two major adjustments this year:
1.Instead of simply using cleaned, dried bones students used a combination of cleaned bones and wings with muscles (that’s the meat) and cartilage still intact. This allowed them to compare the differences between imitating fractures in both situations, and analyze which represents more true-to-life fracture events.
2. This is where the 2.0 comes in. In past years I have had student make sketches and observations based on the fractures they had created, and then answer discussion questions related bone structure and fractures. However, this year we went paperless. Most students carry with them a small computer in their pocket; smart phones complete with a video camera. So the assignment became filming their fracture events while narrating the process. There were 5 main idea they were to include in their video:
- Describe how they will be fracturing the bone.
- Predict what type of fracture they will produce.
- Explain how this fracture may occur in real life.
- Observe the fracture, describe and determine if their prediction was accurate.
- Determine which bones best modeled accurate fractures, why?
These videos were then emailed to me, which I then compiled into a class video that was viewed as a class. Overall, the new tech version of the chicken bone lab was quite successful. Students seemed much more engaged and provided great narration and dialogue regarding the fractures that would not necessarily have occurred in the same fashion if they had been simply writing about what they had observed. Also, filming provided a role of cinematographer to students who were not interested in getting hands-on with the chicken bones. Finally, students love an opportunity they get to use their phones in class without having to sneak a text message from under the desk of a sweatshirt pocket.
Already looking to next year, I plan to delegate the video editing to students who are interested in creating videos. Here is the final video, enjoy.
