Volcano Model Learning about volcanoes is more fun when you make a model that erupts. Making and testing a volcano model makes a good science fair project in earth science. Good genes hypothesis: Good genes hypothesis, in biology, an explanation which suggests that the traits females choose when selecting a mate are honest indicators of the male’s ability to pass on genes that will increase the survival or reproductive success of her offspring.

Although no completely unambiguous examples. Earth Science THE SCIENTIFIC METHOD.
