Lab course that starts with students' own ideas wins Science magazine prize
Date:8/30/2012

ratory section is given a colloidal gold nanoparticle mixture and synthetic urine samples from two fictitious women (one who is pregnant, and one who is not). The students are asked to design a pregnancy test that distinguishes the urine sampleshigher levels of protein, such as the pregnancy hormone human chorionic gonadotropin, bind to the surface of gold nanoparticles, resulting in a color differenceas inexpensively as possible.

Given the success of Exploring Gold Nanoparticles at improving students' overall understanding of the nature of science and scientific models, Rickey says her hope is that winning the IBI Prize and publishing an essay in Science will help her to "share this method of teaching a general chemistry lab, because it has been shown to be more effective at developing students' understanding. I hope people who see the essay will use the module themselves or develop something similar."
