Campers learned about "Gearing Up" by building a device to shoot a plastic lego ball. Campers then applied their knowledge of gear ratios to a race begin the construction of a Drag Racing Robot. Click here to learn more about competition specifics. See pictures of today's work below:
I have always been only a chemistry teacher. For 15 years. Only chemistry. When switching schools, from Sacred Heart Cathedral in San Francisco to Sonoma Academy in Santa Rosa CA, to be closer to my family in Petaluma CA, I was asked to teach Biology and Robotics in addition to Chemistry. I was scared, but so glad I took the risk and jumped in. Biology, has now morphed in "Medical Biology" a class I have created to embrace my failed, yet nostalgic attempts at getting into medical school (3 MCATS...blah blah blah...), and a class called "Engineering for Social Good" that embraces the appreciation and respects for Social Justice that 15 beautiful years at a Catholic school instilled in me. Moral of the story. Do new stuff.
Below is a video from the final showcase for our 2017 Robotics Showcase. Enjoy.
I am proud to serve as the Lead Mentor of Sonoma Academy's very first FRC competitive robotics team. In the spirit of FIRST I am sharing our team's website which will contain all team resources, as well as our business plan embedded below. Our treasury team has been working extremely hard on this document and is excited to share their work. If you are a fellow FRC colleague, please use, steal, modify, etc., as you like :). Good luck to all the teams this year!
Central to the PBL Cycle (see Buck Institute for Education for more info), is the "Public Product" as a final showcase of learning. See image below:
Transcending PBL, I have been tinkering with the concept of a "Public Product" and how to authentically do this in my class beyond a blog post, google document, or the myriad ways I have had students showcase their products to real audiences beyond the walls of our school. All efforts felt/feel forced.
To tackle this in problem, in my Introduction to Robotics Class this year, in addition to our final showcase for teachers and parents where students presented a table (museum style) of their final invention, I showed students various "pitch" videos from the crowdfunding site Kickstarter, and challenged them to imagine that they were doing the same, and to create a video for their invention as if they were going to build a campaign around it. Click here for the simple instructions I gave to my students.
Albeit a hypothetical scenario, by starting with actual videos that contain real dollar amounts raised visible next them, the reality and power of showing your work in beautiful an meaningful ways online was evident. See a sample screenshot from a sample Kickstarter project below. Click here for the pitch video.
To be honest, 5 minutes showing my students pitch videos from Kickstarter empowered them to produce amazing public products more than any rubric, speech or guest lecture I have prepared for them. The final showcase was amazing and their pitch videos, although rough drafts done on via their phone cameras in one class period, embodied and relayed a feeling of potential.
Below are images from one students final project (an Arduino ultrasonic cane for the visually impaired).
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!
