Last year a new feature was added to Google Forms which allows users to submit a file (picture,
video, document, etc.) when completing a form. Today in class I leveraged this feature to facilitate
the curation of a student generated study guide for an upcoming chemistry assessment. Because
chemistry assessments usually involve the production of a handwritten graph, diagram or chemical structure, I had students submit a question in text, then upload a written answer using the file
upload feature. Click here to see the live form. Below is a screenshot of the form.
When all groups completed their question and answer an associated, organized spreadsheet was
created that, when made available to students, contains a question and link to a clear, handwritten answer from each group. Students used their phones to capture the image, and either accessed the form directly from their phone and uploaded via the photo library, or emailed the image to their
computer to be uploaded. Click here to see the live form. Below is a screenshot of the form and a submitted picture.
If you are planning on implementing this, or a similar activity, please play close attention to the
sharing settings in the folder that collects uploaded documents.
If you do not adjust the settings to "public" in the folder (that is automatically created when you
publish a form with a file upload feature) students will not be able to access the links generated
that point to this folder. In the case of the activity described, the ability to access the files is
necessary for students to view the document. Additionally, the "file upload" feature does not work unless the user submitting the form is part of the same domain.
Last week, in an effort to keep both my sections of Honors Chemistry moving at the same pace, I found myself with a day to spare in one section. With a unit on lab techniques, specifically titration, quickly approaching, my thought was to pre train this section on the specifics of the laboratory procedure.
Simultaneously, a more playful side of me wanted to bust out the MakeyMakeys from summer science camp and give students some time to explore conductivity, and tinker around a bit repurposing everyday materials to build something just for fun. Then it hit me: Why couldn't we do both?
Back to titration. Digital Drop Counters used to measure the precise volume titrant added to a flask are nearly $100 with the need for more complex software companions for reading data. This it hit me: Could we recreate a Drop Counter using MakeyMakey (along with the pH probes we already have) to simulate the tools we needed for a successful titration? Yes. Sort of! But super fun.
With the help of a few students we devised a simple workflow: First, students wrote a simple program using Scratch that counted clicks when the space bar was pressed. Then, using some fancy graduated cylinder action measured the approximate volume of 1 drop from our Burets, and added a variable to their program that also counted the volume (in mL) of liquid added along with drop number.
Then for the MakeyMakey! By positioning two wires (one connected to ground and the other to the space button on the MakeyMakey) above the Erlenmyer flask with just enough room for a single drop to complete the circuit, and adding some code to delay the click function for any drops that "stick" to the wires, we were able to accurately measure drops added! Finally something more than a video game controller or banana piano!
It's absolutely no secret that I'm a huge fan of leveraging the MakeyMakey circuit (http://makeymakey.com/) as an instructional device. While there is an obvious connection with such things ha as inventions during a youth science camp, or more creative solutions such as challenging high school chemistry students to create titration "drop counters", the ease of entry and almost limitless potential of this device is incredible.
That being said, the simplicity coupled with power of the MakeyMakey can at times make it seem often, especially for younger learners, as a toy rather than what it is: a modified Arduino Leonardo microprocessor. Keeping this in mind, I have been on a journey over the past two weeks to try and leverage the Arduino Leonardo as a MakeyMakey to create a much better flow in my high school robotics class between programming with the Arduino UNO, and transitioning into using the MakeyMakey as a remote control device.
For example, beginning the year with the Arduino UNO grounds students really well in basic line coding and also input-output microprocessing. From there we transition into using the mBOT, given it's integration with the Arduino language. The integration with the Arduino IDE provides a fabulous flow for high school robotics students. Moreover, with the introduction of the 2.4 GHZ wireless connection between the mBOT and a computer (does not work well with chromebooks) students can easily use Arduino to create their own computer based remote control for the robot.
An obvious connection at this point would be to then leverage the MakeyMakey to create their own remote control repurposed from every day objects such as aluminum foil and Play-Doh. In past years this is been very successful and I say things like "all your long we've been using the Arduino and now you're using a modified Arduino to control an Arduino robot!" Students love this but because the MakeyMakey is so simple to use it's hard for students to make a connection between a raw Arduino interface and the modified appearance of the very aesthetic and simple MakeyMakey.
Back to my point. I am happy to say that I have successfully been able to re-create a MakeyMakey from an Arduino Leonardo and I am very excited to use this in the last phase of robotics class this fall! I am hopeful that the raw look of the Arduino Leonardo with the exact same functionality of a MakeyMakey will create a sense of connectedness in the course for students beginning with simple Arduino UNO programming, ending with leveraging the Arduino Leonardo to create a MakeyMakey mBOT controller. At the conclusion of the year I will show them then the modified Arduino Leonardo "MakeyMakey" as a way of emphasizing invention and accessibility for all.
Below is the instructional video I used as a guide in the creation of the Arduino Leonardo based MakeyMakey Feel free to reach out if you have any questions and expect future blog post on the efficacy of this integration.
I am blessed to teach at a school that incorporates an "Intersession" program into the month of January. Upon returning from winter vacation, students sign up for a two-week-long, 9am-3pm, course of their choosing. Courses are offered by individual teachers and represent areas they are deeply passionate about and would not have time to expose students to during the normal school year. Courses spanned from Fly Fishing, to Mural Painting, to Molecular Gastronomy, to Virtual Reality and even a course designed to break as many Guinness Records as possible in two weeks. Needless to say, it is incredible to see what students can produce an do, when the pressure of grades are removed and students are given ten full days to slowly dive deep into a subject area.
Over the past two years, in addition to my role as a high school science instructor, I have have developed a growing passion for facilitating youth science camps. The MakeyMakey, given its simple implementation, and incredible potential for open-ended invention has always been an an important tool for sparking an interest in science and invention at my camps. See the two videos below to learn more about the intricacies and development of the MakeyMakey.
As is evident in the above videos, while it is an extremely flexible design tool, when introducing young students to the MakeyMakey it is very tempting for them to immediately begin designing video game controllers. While not inherently a bad thing, the potential for more meaningful invention is incredible. Keeping this in mind, I have always wanted to teach a class that leveraged the MakeyMakey as a tool to empower students with either severe physical or intellectual handicaps. The ability to repurpose everyday objects to interact differently with a keyboard, as well as the ability to program and interact with a myriad of different online modules using physical, tactile objects, opens up a world of possibilities for creating Assistive Technology.
My desire to develop such a course was amplified when I stumbled across this website and the below TEDx talk by educator Tom Heck.
Tom and his students brought to life the exact experience I was dying to create, and his website provided a detailed roadmap for how to make it happen! I immediately contacted Tom, and shared my ideas with him. Tom was gracious, excited to collaborate, and eager to discuss his process.
Back to Intersession. My growing passion for leveraging the MakeyMakey as an invention tool, interest in Assistive Technology development, and Tom's TEDx talk serendipitously overlapped at the right time and it was clear that Intersession would be a perfect opportunity to create such a course! After establishing a strong relationship with a local middle school teacher of exceptional students, a few months of brainstorming, I developed this course, and Assistive Technology devices that leveraged not only MakeyMakey, but also Arduino and Scratch, were created and delivered by a passionate team of 11 Sonoma Academy students. Needless to say, it was one of the most powerful two weeks of my career as an educator!
Below is a playlist with three videos captured when delivering the devices to students.
Below are a myriad of different pictures taken during the two-week Intersession course.
