Comment on this resource

At this site the question of the extinction of the dinosaurs takes the form of an interactive matrix. With the hypotheses in the left margin and the types of evidence along the bottom, the resulting squares are indicated in cases where the evidence supports the hypothesis. Students can click on hypotheses to view an animated description, click on an evidence element to get a definition, or click on a marked square in the grid to see how a particular piece of evidence supports a particular hypothesis. Hypotheses include asteroid impact, volcanism, mammal competition and continental drift while the listed evidence elements are rare metal, melted rock, fractured crystals, fossil record, lava flows, sea level, and impact crater.
