The objective of this project is to pick up objects using the fingers. I will have 5 strings controlling 5 different fingers. The fingers are able to pick up objects such as crushed paper into a ball. I got this idea from my aunt who suggested it, she was telling me how it corresponds to prosthetic arms. I was inspired that I could replicate something so high-tech from everyday materials like plastic straws and string. It works like a prosthetic hand, as you pull the springs the straws curl like your joints in your fingers. If I put the hand in a pair of gloves, it can pick small things. The hand is very fragile and something as little as pulling the dental floss too hard can cause the string to detach from the straw. While working on this project, I came across many challenges, and during those challenges, I developed questions. To make the hand Step 1 Gather all your materials Step 2 you need to cut three holes in the straw which would be used as the joints. Please note that the size of the holes matters very much. Also the distance between each hole matters. Step 3 you would get a piece of string and pull it through the straw, do not pull the strings through the holes just put it in the straw. Step 4 you pull the string from the bottom and all three joints should move. Joints are critical in hand movement. In my prosthetic hand, the joints are represented by holes. My questions were if you cut the holes in the hand the same size will the hand still work? If you cut the holes larger will the hand still move all the joints? If you cut the holes closer/farther together will it function better? This work builds upon the scholarship of many individuals. These individuals include the Harvard lab where George Whitesides and Alex Nemiroski reinvented “soft robots”. They were inspired by arthropod insects that can walk, stand, and were able to move on liquid surfaces. Soft robots have a lot of work to be done but in the future, they could help with search and rescue missions and are able to swim in the water. These soft robots are made out of plastic drinking straws. The first time I made the hand all the joints didn’t move. I wasn’t sure why, but as time passed and I found other ways to make the hand I realized that I cut the holes too big. The second time I tried making the hand I cut the holes too close together and too small. After many tries, I realized that the first hole needs to be the largest hole the middle ho/le needs to be medium-sized and the lowest hole needs to be the smallest.","PeriodicalId":329844,"journal":{"name":"2021 IEEE Integrated STEM Education Conference (ISEC)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123637810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two most important objectives are to reduce the cost and make the solution available to the people with minimal infrastructure. Problem Description: Water is critical for life. Even though two thirds of the earth surface is covered with water, not all of it is suitable for human consumption. United Nations statistics show that 1.2 billion people, or almost one in every five, have water scarcity now and another 1.6 billion people do not have sufficient infrastructure to use the water available to them in rivers and aquifers (https://www.un.org/waterforlifedecade/scarcity.shtml). Water extracted from rivers, lakes, and aquifers is not suitable for human consumption in most cases without purification. Water purification is expensive and difficult process which requires chemicals like Aluminum Sulfate. These chemicals interact with suspended solid particles in the water in a process called flocculation, which creates heavy particles that sink to the bottom. After flocculation, the clear water is further purified with Chlorine or other anti-microbial chemicals. These chemicals are produced in expensive factories and require transportation over long distances to reach the intended population. The infrastructure required to collect, purify, and distribute the water is very expensive and requires large capital investment for long term. These high costs and requirement of capital investments are further complicated in politically unstable regions of the world. In view of this background, there is a need to find innovative solutions to the water purification to reduce costs, capital investment, and bring the solutions to the needy people. Research, proposed solution, and results: This research was focused on how different civilizations in the past dealt with the water purification problem, especially when there were no chemicals, factories, and water supply infrastructure. Through this research of literature, one water purification method used by the Indian farmers since ancient times to purify the water available in the ponds they dug to collect the rain water in each field was selected for testing. The rain water collected in those ponds was contaminated by wild life excrements, mud, algae, etc. and was not suitable for human consumption. The farmers made thin pads from dry straw available in the fields and used them as covers for the pot openings. When the pots are dipped into the pond water, these pads filtered out the large contaminants like algae, fecal matter, and heavy mud. Then these pots of water are taken out, mixed with the powder of Moringa Oleifera (drumstick) seeds, let them settle for about 30 minutes or so depending on the size of the pot. The Moringa Oleifera causes flocculation. In addition, the Moringa Oleifera seems to have anti-microbial properties that kill organic contaminants as well. This project tested the effectiveness of M","PeriodicalId":329844,"journal":{"name":"2021 IEEE Integrated STEM Education Conference (ISEC)","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123697959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The REPS project investigates how to best implement engineering learning as defined by the Framework for P12 Engineering Learning. As put forth in the framework, “associated grade-band specific implementation guides will leverage the content of this report to describe and propose appropriate engineering learning across the grades for all children to engage in rigorous and authentic learning experiences to think, act, and learn like an engineer”. The Framework set the conceptual organization for P-12 engineering learning and provided preliminary Engineering Literacy Expectations and Engineering Performance Matrices for high school learners. Leveraging this roadmap provided in the Framework, REPS completes the vision by adding the Preschool (P)-Grade 8 components. The REPS project engages the broader P-12 engineering education community in articulating expectations for engineering learning for early learning, elementary, and middle school students to serve as the connecting elements necessary for authentic engineering learning efforts across the grades. The REPS project brings to bear the combined expertise of educators, professional engineers, and researchers in the field of engineering education to refine and complete a consensus on the nature of engineering literacy development for all students from preschool through high school.","PeriodicalId":329844,"journal":{"name":"2021 IEEE Integrated STEM Education Conference (ISEC)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127106154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This fertilizer is destroying the environment as it is produced from fossil fuels and gets into drinking water. Fertilizer is used to make plants grow faster and stronger, but there is another solution. Changing the peat moss to soil ratio can help plants grow at a faster rate. One ratio that could be used is the golden ratio. The golden ratio is a mathematical concept seen in all aspects of nature. From petals of a flower to a shell of a snail to even human finger anatomy, the gold ratio is used. The golden ratio is $surd Phi quad =( 1 +5) /2$ which is approximately 1.61803398875. This equation derives from the Fibonacci sequence which adds the last two numbers to form the third, such as $0 + 1 =1, 1 + 1 =2, 1 + 2 =3$, and so on. When the two addends are put into a fraction, with the larger number as the numerator, as the sequence goes higher, it becomes closer to the golden ratio. Over a 2-week time span, this experiment will show how using the golden ratio of peat moss to soil will affect lettuce growth. In the experiment, 1 part peat moss and 1.614 parts soil will be mixed in a pot, producing the “golden ratio soil”. Another pot will contain 1 part peat moss and 1 part soil. The plants will be daily monitored for any growth to see which plants will grow faster.","PeriodicalId":329844,"journal":{"name":"2021 IEEE Integrated STEM Education Conference (ISEC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126106071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Techniques such as precision farming, predictive analytics, and geospatial visualization are being used in agriculture to help with efficiency, profitability, and optimization. New Jersey is known as the Garden State for its scenic landscapes and agriculture. Some of its staple field crops include corn, wheat, and soybeans. In particular, this project is focused on analyzing the average amount of soybean yields across the different counties of NJ over the past years to make future predictions. The approach is to use predictive analytics (creating linear regression models and using GIS) on current and past USDA New Jersey soybean yield data. This can then help to discover and analyze future trends. Next, using geospatial mapping (utilizing the ArcGIS platform), the findings drawn from the data will be mapped to provide clarity. These conclusions can be used to provide future direction and make further advancements. For example, an app (that displays the analytics and findings) can be created and translated to the farmers to help provide suggestions on future harvesting and allow them to understand their farms better. In addition, the findings could lead to a further and more detailed study involving AI and satellite imagery of NJ soybean farms/acres.","PeriodicalId":329844,"journal":{"name":"2021 IEEE Integrated STEM Education Conference (ISEC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126681875","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, creating beautiful patterns on the cake is a labor-intensive task that requires a significant amount of skills. For novice bakers to create amazing custom cake decoration, 3D printers can be an invaluable tool. Since its invention in the 1980s, 3D printing technology has evolved significantly to enable various new fabrication capabilities. In the last decade, the food industry has also started to adopt this technology for printing chocolates, candies, dough, or meat. 3D printing has amazing flexibility to realize customized designs with complex geometry, which makes it ideal for cake decoration. Moreover, 3D printers have become widely available as affordable consumer electronics. Therefore, to reduce human labor and skill requirements, we intend to repurpose a 3D printer for cake decoration, which has not been realized before. In this poster, we present the design of a Cream 3D Printer for cake decoration at home. The system is designed to create the desired geometry with cream, produce multiple materials/colors and be affordable (hundreds of dollars). For the initial investigation, the prototype design is modified from a Fused Deposition Modeling (FDM) 3D printer. The four primary subsystems include a 3-axis motion system, a material extruder, control algorithms, and an environment control chamber. For the 3-axis motion system, a Creality Ender 3 Pro 3D printer is selected as the basic structure since it is affordable, opensource, and well-supported by its community. The plastic material extruder is replaced by a custom-designed cream extruder. Whipped cream is placed in multiple syringes pushed by the slider on lead screws actuated by stepper motors. Plastic tubes are used to guide the cream from the syringes to the nozzle for ejection. Multiple nozzles or a single nozzle with multi-way valves can be used to select materials from the syringes. For the control system, G-code generated by the slicer from a Solidworks 3D design can be directly used for single material printing. To select between multiple materials, a custom Python program processes the G-code and uses serial communication to interface with the 3D printer Marlin firmware and an Arduino microcontroller. The environmental control chamber helps to cool the printed cream and improve its rigidity so that complex 3D shapes can be printed. The temperature control can be realized with simple commercial refrigeration systems. At the current stage, the single nozzle cream extrusion capability is completed for the cream 3D printer. Coordinated control of the Ender 3 Pro 3-axis motion system and the custom nozzle has been realized for cream printing. We are currently investigating the effects of temperature and other printing parameters for various potential cream mixtures to identify the configurations suitable for printing.

We offered coding workshops in R and Python. To motivate the students to participate in learning and to practice the learned skills, we set followed a learning workshop with a contest on text data mining.Background -University credit-bearing education is often streamlined to cover increasing amounts of subject matter knowledge in class. It is not usually possible for faculty to take time from their curriculum to develop basic analytics skills, such as the use of R or Python for business analytics. Extra-curricular skills-building activities are an effective vehicle to develop these skills outside class. Research questions - Do extra-curricular workshops to learn coding result in successful learning? Would a coding contest after the workshop drive attendance? What are the elements of a successful workshop and coding contest, and what are acceptable metrics and levels of performance for these contests? Methods- Coding workshops were developed and offered as extra-curricular opportunities for students in a STEM graduate program. After the coding workshops, short-duration coding contests were launched. The goal of the contest was to develop text analytic tools that could be used by the students to advance their academic careers. Attendance in the workshop as a percent of the student body and quality and number of coding contest submissions was a metric of success. Contest participation and successful submissions were a second metric. Results - Two workshops were run with concurrent contests. An average of 10% of the student body registered, and 5% attended. Contest submissions were received, and in each case, at least one submission yielded a usable tool. The tools were subsequently used by students in their job search and to conduct research.","PeriodicalId":329844,"journal":{"name":"2021 IEEE Integrated STEM Education Conference (ISEC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115325551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After cancelling the event in 2020 due to the Covid-19 Pandemic, it was decided to redesign the project and research whether in the midst of current restrictions, improvements in students’ learning engagement could still be obtained even when students would have to work from home and where teamwork could only be practiced on-line. The changes would need to provide a comparable Challenge in each of the four elements of the previous program, and would be validated by a student survey similar to the one conducted for the 2019 paper. Because the project needed to work right the first (and possibly only) time, it was decided to use System Engineering concepts for the re-design, so the project would then become a case study on the use of this technique in an educational setting. The lessons learned from this redesign, and the arrangements developed for the 2021 Robot Challenge competition, may not only be of value for those planning other competitions, but the new on-line system utilized could be readily adapted to reach students living in rural and underserved communities, thus providing them with the same learning experience as those living in metropolitan centers.","PeriodicalId":329844,"journal":{"name":"2021 IEEE Integrated STEM Education Conference (ISEC)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116745934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
