In an ideal world, students would have equal access to education, but that isn’t the case. While some schools have the latest learning technologies, hands-on opportunities, and all the funding they need, others are trying to give students the highest quality education they can without access to these resources. Worst of all, the schools negatively impacted are often in historically underrepresented communities, often ones with large populations of people of color, perpetuating a cycle of poverty. While brainstorming ways of helping our local communities as part of the TIDE Grant (Towards Inclusion, Diversity, and Equity Grant) proposal, providing more equitable access to STEM education was a clear way we thought we could make an impact. Building these STEM kits is a way we Williams students can use our education and access to help build up the community around us.

What is Hands-On STEM Education?

Hands-on STEM education uses physical interaction to provide real-world experiences that help reinforce the concepts being taught. While they can be helpful to the learning process, these experiences are often expensive. Whether it’s premade kits that can cost upwards of 40 dollars a student or involve costly field trips, these experiences often don’t fit within the budgets of schools. This disparity is critical to solve because studies have shown that hands-on learning opportunities help students retain what they learn better than standard learning methods such as lecturing. The problem is exacerbated in the education of younger students (K-6 range) because younger children’s lower attention spans can cause them to lose focus more quickly in the absence of active and experiential pedagogy.

This problem doesn’t only exist in a classroom setting. Many attempts have been made to bring hands-on learning to the home as supplemental education and homeschooling tools; however, cost is even more of a problem here. One of the largest companies currently producing these kits for home use is Crunch Labs. While they are similarly priced, averaging around $30 a kit, the requirement to purchase a monthly subscription typically results in costs of $300 or more per child. Also, Crunch Labs and other kits built for a home environment are often not reusable.

Access to hands-on STEM education is so important because high-quality STEM education improves students’ creativity and problem-solving skills. Research has shown that exposing kids to STEM in elementary school – especially between the first and third grades – provides students with the foundation they need to succeed in STEM-field careers. According to the research, U.S. adults with 1-2 years of experience in the workforce have reported the highest exposure to STEM concepts in elementary school. Between the ages of 5 and 8, 46% of this population experienced a STEM-related track in school and 53% of this population currently works in a job that is either entirely or heavily involves STEM – by far the largest percentage of any sector of jobs in the workforce. This suggests that exposing students to STEM at a young age captures their imagination and keeps them interested in science, technology, engineering, and math jobs early in their careers.

As student workers in the Makerspace, Divine Uwimana ‘27 and I, Elena Sore ‘27, met and collaborated with Paula Consolini, Adam Falk Director of the Center for Learning in Action, Tanja Srebotnjak (Director of the Zilkha Center for Environmental Initiatives), and David Keiser-Clark (Makerspace Program Manager). We identified a few critical criteria for STEM kits:

  1. Our STEM Kits need to be as low-cost as possible to produce. To ensure this, we must find creative ways to reduce material usage and implement supplies students may already have in their classrooms into the kits.
  2. We must design STEM kits to leverage existing lesson plans and learning requirements to ensure that the STEM kits fulfill the educational needs and standards set out by organizations like the Department of Education. 
  3. The STEM Kits must be designed to be reusable, durable, and sustainable, using sustainably sourced and produced materials wherever possible.

Brainstorming

Divine and I began the brainstorming process by researching existing STEM kits currently available on the market and how we might further improve them for our demographic group with respect to the aforementioned criteria. Since we both had little experience in the field beforehand, we wanted to understand better the design features other organizations used to create highly engaging STEM kits. Some of the qualities we observed that we believe we should replicate are listed below:

  • A good STEM kit is highly interactive. Parts of the kit, especially mechanical parts, should be designed so that students can visually see what is happening and how the action they are putting in is causing the final result.
  • A good STEM kit should not be a “one and done.” Ideally, a STEM kit will have multiple stages that allow students to build upon a product in stages, introducing new concepts or building on previous concepts.
  • A good STEM kit should be a manageable length. Even if students are having fun, dragging it out too long risks boring the students and causing the learning aspect to be ineffective.
  • A good STEM kit should be fun yet educational. This means balancing the kit to both be rich in academic concepts and interesting to keep them engaged.
  • A good STEM kit should encourage teamwork and cooperation. It should allow kids to work together to build their social skills while learning.
  • A good STEM kit should allow “trial and error.” It should enable the kids to learn from mistakes and thus build their problem-solving skills.
  • A good STEM kit should be simple yet visually complex. Just because the final mechanism is a complex contraption doesn’t mean the process of assembling it can’t be simplified and streamlined.

During our design process, we also got to experience assembling a STEM kit first-hand, specifically the mechanical Scotty dog kit we received from Carnegie Mellon University, courtesy of Professor Bill Nace and Professor Robert Zacharias. The materials used to assemble it are easy to manufacture, primarily made of thin sheets of wood and acrylic with 3D-printed plastic parts. The design is simple but very interesting; a single motor in the middle drives both the tail wagging on the back and the head bobbing on the front through a system of gears on the back. The head is made to bob up and down in a specific pattern through the radius of the spinning piece increasing or decreasing as it turns, creating a pattern of head movements that feels random. The tail spins on an arm and is locked upright using a bracket, making the tail wag back and forth with a simple spinning motion. Finally, all of this is controlled with a light sensor, allowing the user to control the speed of the motion by raising or lowering their hand above it. All these mechanisms combined to create a fascinating kit from a design standpoint, with a lot of interactivity and interesting mechanisms on display while being very quick for us to reassemble, even without instructions.

From this experience, we better understood how to design an effective STEM kit. Then, we started brainstorming ideas for STEM kits that we could create. At the end of this brainstorming, we ended up with three designs we wanted to develop further. The first is a model car, which would use a wind-up mechanism built by students to showcase the properties of potential and kinetic energy. The second idea is an energy kit expansion for the car, allowing students to electrify it while teaching them the basics of electricity and explaining renewable solar energy concepts. Finally, the third idea is a solar system kit, which would be focused on having students assemble a solar system model to teach about the planets in our galaxy and our place in the universe. With these initial ideas, we started prototyping the model car kit.

Prototyping the Model Car Kit

The main idea of our wind-up car kit was simple. But, as with many projects, it quickly evolved into a complex design with many digital iterations and three 3D printed prototypes. For this first design, a 3D printed base would connect the two cardboard sides and help support the back axle, which would wind up using a rubber band attached to it and the frame. Wooden dowels would act as axles and bottle caps as wheels, so when you pulled it back, the car would launch forward using energy stored in the rubber band. 

While this was a great initial idea, we encountered some problems. First, cutting out the sides made of cardboard proved difficult because two holes needed to be cut in the middle of it for axles. Ultimately, we decided that the side pieces should be replaced with laser-cut wood in the final design, which would be reusable and easier for kids to work with while providing more structural rigidity. Another issue we discovered was that the rubber band would stay on the axle instead of coming unhooked at the end, catching it, and abruptly stopping the car. Our solution was to move the hook point for the rubber band forward so it had enough energy to detach itself from the axle at the end. We also had to ensure this expansion didn’t use too much plastic, as we hope to create all the filament ourselves using recycled PET from locally gathered plastic bottles. We ended up using a honeycomb pattern, often seen in structures that use empty space to save material resources while retaining structural integrity, and by implementing this we were able to save sufficient plastic such that the larger prototypes consumed less plastic than our smaller initial prototype.

Our first three prototypes for the 3D printed base, showing how it evolved to meet the project's needs while remaining efficient in plastic usage.

For our third prototype, we rounded and smoothed as many parts as possible to prevent sharp points or edges that can occur in 3D printing. We also did this to prevent sharp points from catching or breaking the rubber band. Finally, we modified the slot at the front for the rubber band to help the car retain it, even after it detaches from the axle.

The biggest problem we ran into was not with the design of the base but with the kit itself. Our initial idea was interesting but violated one of our initial design rules. The kit was just one thing: assembling the car with the rubber band. If we wanted to make an exciting kit, we had to make at least one additional stage involving more engineering and differently demonstrating the concepts of potential and kinetic energy. 

While looking for inspiration, we stumbled upon a design by a maker named Greg Zumwalt for a 3D Printable Wind-Up Car that used a simple mechanism to limit the speed, allowing it to move farther and longer after windup as opposed to a design like ours, which simply went at top speed after release. Looking into this project’s mechanics, we realized that a similar design could be perfect to demonstrate the ways energy can be modified in the process of converting from potential to kinetic energy. So, to better understand how the mechanics worked, we downloaded the files and began printing them out to design a similar mechanism within the constraints of our model kit.

It was at this moment that the Office of Institutional Diversity, Equity, and Inclusion announced that our application for a TIDE grant was accepted and that our STEM kit project would be funded. 

Next Steps

Our next steps are to complete the second expanded energy source for our car prototype, align that with curricular concepts, and then meet later this month with an elementary school teacher to share our project and hear initial feedback. We plan to incorporate that feedback into the car prototype and then next meet with that teacher’s class and observe student reactions to utilizing it. As we continue to build several STEM kits, our theme will be to test, demonstrate, observe, seek feedback, iterate, and repeat. We hope these kits might have a significant impact on elementary students’ education in the Berkshires.

Whittle by Whittle: Envi Center Garden Signs 

Posted on by

When I was a prospective student, I recall my host bringing me near the Class of 1966 Environmental Center (“Envi Center”) to meet some of their friends. While passing through, I noticed a group of students picking apples from a tree and pulling weeds in the garden beds. As I took an apple from their bin and had a bite, I was incredibly overjoyed to see a garden after just having started one at my high school. Now, as a student and summer intern, I had the opportunity to see the hard work that goes into the maintenance to make the gardens a community space for all. This is why, when Christine Seibert, the Sustainability Coordinator at the Zilkha Center, reached out to the Makerspace for a project to make signage for the Envi Center gardens, I jumped at the opportunity to support this project!

Garden Beds behind the 1966 Environmental Center

The garden beds are an integral part of the Envi Center. Under the Living Building Challenge certification, the building is required to operate as a net-zero energy and water space, with 35% of the surrounding land area in food production. The beds are supported by the Center for Environmental Studies (CES) and the Zilkha Center (ZC), and maintained by ZC interns and Williams Sustainable Growers (WSG). Additionally, Landscape Ecology Coordinator Felicity Purzycki advises overall orchard maintenance.

These gardens provide opportunities for community building, food production, and help teach students new skills. With these goals also come challenges. While talking to Christine about the signage project, she mentioned how garden interns already have a lot to do maintaining the gardens. This has made it difficult to find bandwidth to create signage about what is being grown and share meta information about the gardens. In addition, the current wood cookies used for signage are beginning to fade. For more than four years, the Zilkha Center has wanted a more permanent and prominent solution to identify and distinguish plants grown; this will also help ZC interns and other people to know what is ready—or not—to pick. The new signage will cover three areas: identifying the perennial and annual plants, teaching people how to use the gardens through the honorable harvest, and when certain items are ready to be picked.

Inspiration was taken from a project recently completed by Yoheidy (Yoyo) Feliz ‘26, who engraved wood slabs to make signs for visitors going through the virtual exhibit tour at the Stockbridge-Munsee Tribe’s exhibit in Stockbridge. Those wood slabs were sourced from Hopkins Memorial Forest which is also where our project’s journey began!

We received Sugar Maple logs claimed from the old grove across from the sugar shack with the support of Josh Sandler, Interim Hopkins Forest Manager. This tree fell two years ago, and had not yet been repurposed; the tree was part of the maple sugar grove that has a long history of being used for maple sugaring in Hopkins Memorial Forest. The logs were harvested with the help of a chainsaw by caretaker Javi Jenkins-Soresnen ‘25 who has a lot of experience in forestry.   

Logs into Lumber

Once we received the logs, we had a series of sessions in the Williams Hopper Science Shop with Makerspace Program Manager David Keiser-Clark and Instrumentation Engineer Jason Mativi. Our goal was to mill the logs into 35 planks measuring 4″x20″ with approximately a 1″ thickness. We purchased cedar posts—that had formerly been telephone polls—locally from the Eagle Lumber sawmill in Stamford, VT. In the end, we were able to create exactly 37 planks, leaving us with precious little room for error.                

Given the unevenness of the natural logs received, the first step was to build a sled (a platform) that would stabilize each log as we sliced them into planks with the bandsaw. We affixed each log to the sled with a couple screws (carefully avoiding the path of the bandsaw blade), sliced to create a flat side, then rotated the log 90 degrees and sliced again. After making two contiguous flat sides, we were able to slice the log more conveniently by using the bandsaw fence and tabletop.

After cutting each plank, we let them dry for a week; this allowed them to shrink and to cup or curl (warp) a week. Before drying, the maple measured between 8 to 20% moisture content. Typically when letting wood dry, you want to stack your lumber with spacers to allow air flow to all sides, and allow it to dry for six months or more. Because we were short on time, we used spacers and placed weights on top of the stacks, hoping to aid them in drying flat. After a week of drying, we were able to visually see shrinkage and some warping. 

We then used the wood jointer to create one flat edge; this process created a nearly perfectly flat and square edge that was perpendicular to the wider section of the board. We then placed that flat edge against the fence of the table saw to create a second clean edge parallel to the jointed edge. We used the jointer again to create a nearly perfectly flat surface on the wide side of the board. Next we used the thickness planer to flatten the top face of the plank and be parallel with the bottom face. This work resulted in creating beautiful rectangular sugar maple planks that were both parallel and square. We repeated this process for each board.

Engraving

After we had jointed, sliced, and planed the maple logs into boards, Mativi and David taught me how to use the Epilog Laser Helix engraver to make a Welcome sign, informational signs for the Rain Garden, Solar Meadow, and Picking Sign, and also 31 plant identification signs. It was my first time using a laser engraver and I had to be conscious about placement, size, as well as laser power and speed. Using CorelDraw (software), I centered each sign’s text to the middle of the engraver platform, which ended up being 12 inches on the x-axis and 9 inches on the y-axis. I worried endlessly about placement and sizing so I first experimented on matboard. Despite my experimentation, I still had some underlying issues given varying thickness and placements that are evident in my very first attempts at engraving. Each laser engraving requires 15 to 20 minutes, and I often repeated that process two or three times to burn a deeper image into the wood.

Next Steps

I expect to complete laser engraving all of the signs within the next two weeks. The next step will be to affix the signs onto cedar posts; Jason Mativi has already cut those into 48” lengths including a spiked tip to make it easier to drive them into the ground. The final steps will include sanding the sharp corners and adding a 100% natural Walrus tung oil preservative to better show the grain and improve longevity. Because our wood is dry, we will increase the ratio of tung oil and Citra solvent from the standard 1:1 to instead be a 2:1 ratio (2 parts tung oil, 1 part citra solv) and then warm that mixture and add in beeswax (4:1 ratio of tung/citra to beeswax) for additional protection. It will be exciting to see the signs all over the Envi Center gardens!

Makerspace Collaborating on Multiple Sustainability Projects

Posted on by

Last spring semester, the Makerspace @ Williams College pivoted to focus on academic projects that support teaching and learning goals; previously, this focus had been an aspirational goal. The Makerspace Program Manager, David Keiser-Clark, and his team of amazing student workers, now support a dozen interdisciplinary academic and campus projects at a time. A quarter of these projects support sustainability, or specifically the Zero Waste Action Plan, including: (1) a three-college collaboration to create an eco-friendly deterrent for Japanese Beetles in our community garden; (2) a prototype to upcycle plastic bottles into 3D printer filament; and (3) a set of laser engraved wood signs, sustainably harvested from Hopkins Forest, for a Stockbridge-Munsee led garden video and audio tour at the Mission House in Stockbridge, MA. Below, you’ll find a brief spotlight on each project, and possible ways we might build on these initial efforts.

E4 Bug Off Team Project : Mitigating Japanese Beetle Damage

The E4 Bug Off Team is a collaborative environmental project between engineering students from Harvey Mudd and Pomona Colleges, and students working with the Williams College Makerspace and Zilkha Center. The engineering students researched and developed a prototype that would safely repel Japanese beetles to hopefully stop them from defoliating raspberry bushes in the Williams College Community Garden. The Makerspace used 3D printers to create the parts and subsequently assembled the model. Zilkha Center interns then deployed the model in the gardens. The device is designed to be low-maintenance and only needs the reservoir filled weekly with 100% peppermint essential oil. Japanese beetles, in addition to other bugs and mammals, dislike the smell of the mint family, and the concentrated peppermint essential oil diffuses into the air via permeable wicks that extend from the reservoir tank.

The initial model was installed in the garden in July 2022, at the tail end of the raspberry season, and immediately leaked. This spring (2023), the Makerspace re-printed the reservoir tank with a higher density (50% solid as compared to 15%), tested the model and, after 24 hours, found it to be 100% water-tight. This second model was introduced into the garden with mixed results: the functional model performs as intended, but the impact is difficult to measure without a control plot or method of measuring beetle activity this year. 

In addition to recording measurements of a control plot, additional steps to increase effectiveness could include fabricating additional models to better saturate the air within the berry patch or returning the project to the engineering team for design modifications. The final version would be printed with ASA filament, which is physically stronger and UV/moisture resistant, as compared to PLA or ABS filaments.

Polyformer: Sustainable 3D Printing at Williams College

While completing a month-long Zero Waste Internship at the Zilkha Center (through the ’68 Career Center’s career exploration Winter Study course), Camily Hidalgo pitched building a machine to convert waste plastic into usable 3D printer filament. The project aligns with the Williams College Zero Waste Action Plan, which is based on the sustainability strategy in the Williams College Strategic Plan. She envisioned this as being a collaborative effort between the Williams College Zilkha Center and the Makerspace. 

After researching several options, she selected the Polyformer because it is an open-source (publicly accessible) project that seeks to create a DIY kit, composed of standard and commonly found parts, able to convert and upcycle plastic bottles (waste) into usable 3D printer filament. This project was launched in May 2022 and has quickly amassed more than 4,000 people who follow and/or contribute to the project (on Discord), while a core group of dedicated volunteers develop the project.

Many of the 78 printed parts that will be assembled into the Polyformer.

The intended outcome is to build a machine, based on standardized specifications, that effectively slices a water bottle into a half-inch wide ribbon, and then feeds that ribbon through a heated funnel, called a hot-end, to extrude it as 1.75mm PET filament. Camily seeks to create a working prototype to demonstrate our ability to disrupt our plastic waste stream and upcycle that into usable 3D printer filament. Approximately 40 bottles are required to create a standard 1 kg roll of filament, (enough to print 6 of the aforementioned beetle devices!). This project seeks to raise awareness that we can both reduce the quantity of waste that the college ships offsite while using that waste to create new filament and thereby purchase less of that virgin material from China. Upcycling waste can reduce the environmental impacts associated with the extraction of raw materials and product manufacturing as well as the significant carbon footprint associated with shipping those products to us from the other side of the globe.

Camily Hidalgo notes that this project is complicated because the design is constantly being improved. Additionally, it requires 3D printing 78 individual parts and then assembling those with a kit of sourced materials that includes a circuit board, LCD screen, a volcano heater block and 0.4 mm hot end, a stepper motor, stainless steel tubing, bearings, neodymium magnets, lots of wires, and lots of metal fasteners.

This project began last spring semester and, as of this summer, all 78 parts have been locally printed. Assembly has begun, and will be completed during the fall semester, followed by actual testing under a science lab exhaust hood to safely capture antimony, a VOC released when PET reaches its melting point.

The Stockbridge-Munsee Community Historic Preservation Office summer intern, Yoheidy Feliz, reached out to the Zilkha Center for help with creating locally sourced wooden signs for a permanent video and audio tour at the Stockbridge-Munsee Garden in Stockbridge, MA. She received a dozen sugar maple and red maple discs, plus locust wedges, all sustainably harvested from already fallen trees in the Williams College Hopkins Forest. 

Yoheidy approached the Makerspace and, in collaboration with expertise and tools from the Science Shop, learned how to use an industrial laser engraving machine to etch a welcome sign with QR code, as well as multiple audio guide messages, onto sanded wooden discs. She attached these discs to sloped wooden bases (“wedges”) using woodworking dowel joinery, wood glue and a mallet, and then applied a natural, non-toxic preservative coating of Walrus-brand tung oil. 

Yoheidy sits with her series of laser engraved wood slabs. She later added a laser engraved metal QR code label that directs users to the hosted video tour.

Cloning the Last of its Kind

Most recently, Associate Professor of German, Chris Koné, approached the Makerspace with a problem: all but one of the file hanging clips to his beloved office desk had broken. The result: piles of overflowing manila folders surrounding his desk, cramping his office and style. He searched Ebay, Etsy, and Amazon, but was unable to find replacement parts. He even visited a store in NYC that specializes in providing office parts. Alas, the parts were obsolete. So he approached the Makerspace and asked if we might be able to replicate his last remaining viable part.

Milton Vento, the Makerspace’s summer student worker, took on the task as his first project, using it as an opportunity to learn photogrammetry, an accessible and low-cost method of taking many photographs of an object from varying angles and then using software to stitch them together into a 3D digital object. He expanded the project by testing four different methods of creating 3D objects using: standard manual DSLR photogrammetry with Metashape software; photogrammetry using a smart turntable that rotates and sends an infrared signal to the DSLR camera, causing it to iteratively release the shutter and then advance the turntable several degrees and then repeat that process; an older DAVID5 object scanner; and the RealityScan app that requires only a smartphone. This exploration resulted in two distinctly more efficient workflows that will become standard use this fall in the Makerspace. 

He also successfully re-created a 3D object of the final remaining desk part, and printed and delivered a half dozen of these parts to Chris. Should any of these ever break, the file can easily be retrieved and re-printed.

Future Project Ideas

One upcoming and likely collaboration between the Makerspace and the Zilkha Center would be to laser etch additional sustainably-harvested Hopkins Forest wood slices to create signs for the Williams College Community Garden. Additionally, the Zilkha Center, Makerspace and MCLA Physics and Environmental Center may brainstorm the possibility of creating a larger prototype for upcycling plastic into pellets. The pellets could then be used for injection molding, given to local artists for artwork, or sold regionally; this idea was sparked by Smith College’s collaboration with Precious Plastics.
