Grossology for Teachers "Grossology" adds zip to my elementary school science lessons. The information appeals to the 8 - 12 year olds, and fits neatly into the lessons as an enrichment. The kids now beg to have science, expecting at some time in each unit there will be "a really neat experiment". Children also ask to borrow the book. One mother states "My son never liked reading. He borrowed your book and then asked me to buy him some more. Now he reads every night before he goes to bed." I think teachers or parents both would do well by ordering this book.
