Students combine intense enjoyment with important concepts in chemistry and physics through imaginative experiments with soap bubbles. They devise an ideal bubble-blowing instrument; test dishwashing brands to see which makes the biggest bubbles; determine the optimum amount of glycerin needed for the biggest bubbles; employ the Bernoulli principle to keep bubbles aloft; use color patterns to predict when a bubble will pop; and create bubbles that last for days. This guide is packed with solid scientific, technological, and mathematical content and learning. An extensive background section on bubbles is included. Grades 5–8 10 Sessions (6 Activities) 80 pages ISBN: 0-924886-58-7 |
