Modeling the Alimentary Canal
In this activity, students use string to model the gastrointestinal tract as a scale model. I’ve noticed that students do have difficulty with the concept of scaling, which is one of the crosscutting concepts listed in the NGSS. The directions give students measurements for a 1/3 scale model, the human alimentary canal is about 9…

Investigation: Modeling Heredity with Popsicle Sticks
In this activity, you will use popsicle sticks to model the process of gamete formation and the combining of sperm and egg to create offspring. Results of the simulation can then be compared to Punnet square expected results. Popsicles should be made in advance, the set contains a male and female set with the genotypes…

Case Study: John Snow and the Origin of Epidemiology
This case study explores a time before the Germ Theory when doctors were uncertain how disease was spread. Current models, such as the humoral or miasma model could not fully explain how cholera infected some households, but not others. This case story explores London, England in 1854 after an outbreak of cholera which had…
