You are required to write one short term paper during the semester. There are three different types of papers you may choose from. Choice 1 is called “The Aunt Gladys Letter”. For this assignment you will pretend that your Aunt Gladys has sent you a letter asking a question that she has been wondering about. If you choose to write an Aunt Gladys letter, you may select a topic from my list, or if you have an idea of your own, you may submit it to me for approval. Topics will be assigned on a first come, first served basis. Examples of topics include “How do scratch and sniff things work?” and “Why does biting on aluminum foil make your teeth hurt if you have fillings?
