Brief description:
 

Students will be divided into 2 groups to compete on the number of moebius strip they can produce.

 
In the first round, capital is fixed and technology is primitive. Since an additional student (a variable factor) will be added into the production process after every 30 seconds of production, the law of diminishing marginal returns will be observed.
 
In the second and third round, a new piece of capital and a "high-tech" capital will be added respectively. Thus, students can observe and experience the effects on production, especially when they are required to record their production data and plot the
TP, AP and MP curves.
