1. Students examine the historical development of the regulation process to obtain governmental approval for new drugs and medicines. They will consider a modern day example using “lily juice,” a hypothetical herbal remedy promoted to increase intelligence. They learn about thresholds, concentration, toxicity, and qualitative and quantitative data. Simulated toxicity tests on rats provide data that can be analyzed to decide whether the product should be distributed.
2. Students will investigate light, color, and how our eyes work. They will experiment with color filters, decipher secret messages—and why an apple looks red. They will use diffraction gratings to appreciate how many “hidden” colors a source gives off, even though our eye perceives only one.
