This lab activity takes students on a unique journey through the world of neuroscience and engineering to explore the complex nature of Parkinson's Disease. Students will simulate the motor symptoms of Parkinson's Disease firsthand by experiencing disruptions in motor control aimed to foster empathy for those living with the condition. Integrating biochemistry, neuroscience, and engineering principles, this lesson is a powerful tool for inspiring the next generation of scientists and empathetic individuals.

SummaryMy high school students are creating assistive devices for visually impaired individuals using the Arduino Uno platform. This project focuses on developing innovative digital mobility aids, utilizing ultrasonic sensors and small servo motors. These aids are designed to enhance spatial awareness for visually impaired users through sound and tactile feedback, alerting them to nearby objects. I am hopeful that this initiative provides practical, real-world applications of technology but also attempts instills a deep sense of empathy and innovation in my students. Procedure
I was honored to teach an elective class called "Engineering for Social Good" last semester. Our final project in the course was the design of computer controllers for individuals with quadriplegia. Our goal was to create prototypes, and then share the construction process on the site Instructables for individuals to recreate. The entire engineering design process can be seen on our class Padlet shelf here. A final student Instructable can be seen here. See a few images below. See a video of a controller in action below.
My "Engineering for Social Good" class just completed a three-week design cycle leveraging the MakeyMakey in the 100% distance learning setting. I have written about similar projects before, and I am, yet again, amazed by the power of the the "shelf" feature in Padlet for student public showcase, collaboration, and tracking of the design cycle. See embed the entire cycle below.
*Note: The below lesson is only an outline meant to encourage deeper thinking about the 5E cycle.
Standard
NGSS: HS-LS2-3: Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions. 1. Engage
Display the below image and ask the question: What are you curious about?
Desired student questions include, but are not limited to, the below:
*Purpose: To surface content related questions without explicitly asking students. 2. Explore
Teach how to leverage Arduino Uno to create their own Pulse Oximeter. Click here for instructions and materials. Once complete challenge students to design and conduct an experiment to determine the impact that various types of exercises and activities (breathing through a straw, etc.) have on pulse and oxygen saturation. Students will then hypothesize the relationship between pulse, oxygen saturation and energy use. Experiment must be conducted using appropriate research design methodology. (Control, independent, dependent variables outlined clearly)
*Purpose: To challenge students to think deeper about energy during exercise and strain, as well as revisit research methodology and promote crosscutting NGSS integration such as engineering, etc. into the lesson. By not addressing "Blood Doping" directly, students are left wondering the relationship between the "Engage" and "Explore" phase further intensifying their curiosity and desire for more content. 3. Explain
Conduct a lesson on Cellular Respiration, clearly outlining and diagraming the process of Glycolysis, Krebs cycle, and defining organelles such as the cytosol and the mitochondria. Once complete, ask the driving question: How does the processes outlined relate to "Blood Doping". After students share their responses, play the video below:
*Purpose: To deliver basic content (diagrams, processes, vocabulary) to help students make a deeper connection between the "Engage" and "Explore" phases.
4. Extend
Pose the below medical case study to students and challenge them to:
A, 23-year-old, 5’ 9”, 105 lb, caucasian female presented in her physician’s office with a sudden onset of weight loss along, pain when urinating, and chronic extreme hunger. The patient also reported a strange mold-like substance forming in her toilet over the past week. *Purpose: To facilitate connection between information obtained during the "Explain" phase and applications of content in the "real world" (note: I hate the term "real world" but application can extend beyond medical diagnostics, etc.). 5. Evaluate
