- W288501310 abstract "[ILLUSTRATION OMITTED] Princeton High School is a relatively large, urban, four-year comprehensive high school that serves approximately 2,000 students in Cincinnati, Ohio. Academic offerings include, among others, the International Baccalaureate program, technology, business, and general studies. Approximately 82% of the graduates attend college, with 60% going to four-year schools and 22% enrolling in two-year/technical schools. Before utilizing the Pop[R] Challenge in a new engineering class next year, I tested it with four engineering drafting students. It was quite successful, and the students had a great time. Overview Students are assigned the task of helping the Tootsie Roll Company to answer the age old question--how many licks does it take to get to the center of a Tootsie Roll Pop[R]? Students can use any means available to complete the challenge, including viewing the following Tootsie Roll[R]-related websites at www.tootsie.com/howmany-sb.html and www.tootsie.com/ memoriesLicksMachine.html. How many licks does it take to get to the center of a Tootsie Roll Pop[R]? This was the question I posed to my engineering drafting class. None of the students had ever worked on a problem-solving activity like this. They all planned to go into engineering at the university level next year and wanted a challenging project that was not drafting-related. The original idea came from a cooking show, but I wanted to make a lab out of it. The first step was to ask the students to do some research to determine if an answer even existed. After consulting the Tootsie Roll[R] website, they discovered that engineering students at Purdue University had worked on the problem. They saw an example of the machine used by the Purdue students, and then began the design process, working on a solution of their own. Engineering Discipline(s) Since my students had no experience with different engineering fields, I explained to them they would be working on the study of mechanical engineering. One of my first tasks was to teach them about gears and gear ratios. Your students may also discover the involvement of some chemical engineering. As the Tootsie Roll Pop[R] gets smaller, you will need to figure out, why? If your results are anything like ours, the sugar buildup on the tongue material will become saturated and then the design may begin to fail, necessitating a project redesign. Standards For this lab, I found that we used the following STL standards: 1. Students will develop an understanding of the attributes of design. (Standard 8) a. The design process includes defining a problem, brainstorming, researching ideas, identifying criteria and specifying constraints, exploring possibilities, selecting an approach, developing a design proposal, making a model or prototype, testing and evaluating the design using specifications, refining the design, creating or making it, and communicating the process and results. (Benchmark H) b. Design problems are seldom presented in a clearly defined form. (Benchmark I) c. The design needs to be continually checked and critiqued, and the ideas of the design must be redefined and improved. (Benchmark J) d. Requirements of a design, such as criteria, constraints, and efficiency, sometimes compete with each other. (Benchmark K) 2. Students will develop an understanding of engineering design. (Standard 9) a. Engineering design is influenced by personal characteristics, such as creativity, resourcefulness, and the ability to visualize and think abstractly. (Benchmark J) b. A prototype is a working model used to test a design concept by making actual observations and necessary adjustments. (Benchmark K) c. The process of engineering design takes into account a number of factors. (Benchmark L) 3. Students will develop abilities to apply the design process. …" @default.
