In one of the best-known and most popular GEMS guides, students explore important concepts in chemistry and physics through imaginative experiments with soap bubbles. Investigations include: devising bubble-blowing instruments; employing the Bernoulli principle to keep bubbles aloft; creating bubbles that last for days; and using color patterns to predict when bubbles will pop. Jacqueline Barber is the Director of GEMS and the author of Dry Ice Investigations and Parent Partners.
