This activity demonstrates the concept of 'cycle time' within a basic assembly line, which is the time it takes to assemble a part or product. Work that is done to build skateboards is simulated through videos and animations, allowing students to experience the basic steps of the manufacturing, or assembly, process. Students can calculate the time it takes to assemble various parts of the skateboards well as the entire skateboard. Students can also gain an appreciation for how changing, or redesigning, the work can impact the cycle time.
K-12 STEM Activities (REMS): Activities
This activity demonstrates the process of balancing an assembly line, which is designing the same amount of work content, or time, at each workstation. Work that is done to build skateboards is simulated through video and animation, allowing students to experience the basic steps of the manufacturing, or assembly process. Students will learn how changing the work being done at each workstation, or changing the number of people working, can impact the flow of the assembly line and the utilization of each operator.
This activity allows students to analyze data from performance testing on skateboards. The purpose of wheel bearings reducing friction and its effect on the performance of the skateboard are discussed. Students make predictions, interpolate, and extrapolate based on given data. The transfer of energy is demonstrated and discussed as it relates to the skateboard performance testing.
Distribution and Logistics
This activity introduces systems for meal picking at distribution centers for patient cafeterias in hospitals, airline meal services, etc. Systems designs are discussed and tested through computer simulations. Students calculate average picking times and brainstorm ways to improve the systems designs in order to decrease overall picking times. The Pick-to-Light System is introduced, which is a digital system used in warehouses for picking, sorting, and preparing orders. Students perform a cost analysis based on data retrieved from computer simulations.
The term “ergonomics” refers to the practice of designing products and systems that accommodate the physical limitations of the human body. Engineers consider these limitations and how to apply this information to the design of products so that people can use them safely, comfortably, and easily. Ergonomically designed products reduce the chance that people who use them will experience discomfort or injury. In this activity students will measure the dimensions of the human body to evaluate the design of a classroom chair.
This activity allows students to analyze design systems for recycling household containers using single stream processes at Materials Recovery Facilities, as done by industrial engineers. The process of recycling is introduced, advantages and disadvantages of recycling are discussed, and cost analyses are calculated using mathematical strategies.
Smoothing the flow of patients in and out of hospitals and other health care settings can help to reduce overcrowding, prevent poor handoffs, and avoid delays. A number of hospitals and health systems are calling on industrial engineers to analyze current systems and design new ones to improve patient flow. In this lesson, students will simulate a walk-in healthcare clinic, collect and analyze data, and then make suggestions for an improved design.
Engineers design systems to be used safely, comfortably, and easily. The term “ergonomics” refers to the practice of designing products and systems that accommodate the physical limitations of the human body. Ergonomically designed systems are easier and more comfortable to use and reduce the chance that people will experience discomfort or injury while using the system. Often, ergonomically designed systems also enable people to be more productive. In this activity students will evaluate the layout of a medical supply cabinet. After making observations and collecting and analyzing dat
Medical wastes can be generated from routine exams in doctors’ offices, from surgical procedures at hospitals, or from research done in labs. They may include sharps, wastes that can be treated on-site, normal wastes, medical wastes, or hazardous wastes. In this lesson, students will analyze methods used for sorting these waste, discuss the disadvantages of incorrect disposal, and brainstorm methods to make sorting easier and more efficient.
