This 7 minute video segment from Catalyst describes an excellent example of how biologists have worked to investigate and solve a problem of an invading species of sea urchin that was devastating a marine ecosystem. The scientific approach to develop a biological control needed to rely on technologies such as radio tracking ...

This is a problem-solving activity in which students are engaged in a challenge is to control virtual bridges using expansion and contraction so that a car can pass over them. In so doing they learn about the expansion of solids, liquids and gases when heated is applied. Students need to understand how a bimetallic strip works.
