K-12 STEM Activities (REMS): Activities

Contemporary Manufacturing

Skateboard Assembly – Cycle Time

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.

Curricular Subjects:
Comparing Rational Numbers, Calculating Averages, Determining Percent Change and Cumulative Percent Change, Modeling (using Cost Analysis), Solving Linear Equations and Systems of Linear Equations
Skateboard Assembly – Line Balance

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.

Curricular Subjects:
Rounding, using formulas, percent change, slope, linear equations, modeling
Skateboard Assembly-Performance Testing

Content for this section is being worked upon and will be provided in the near future. Please check back.

Distribution and Logistics

Meal Picking

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.

Curricular Subjects:
Dependent and Independent Variables, Calculating Averages, Analyzing Data, Modeling (using Cost Analysis), Linear Equations
Ergonomic Design

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.

Curricular Subjects:
Collecting data, ordering fractions and percents; calculating statistical measures of central tendency, normal distribution, percentiles, summarizing data using statistical representation: histograms, stem-leaf plots, etc.
Household Container Recycling

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.

Curricular Subjects:
Rounding, Multiplying Decimals, Converting Units of Weight, Comparing Density, Magnetism, Bar Graphs, Percent Change, Comparing Data, Making Predictions, Modeling (using Cost Analysis)
