In this activity from Mystery Science, students investigate the hypothesis that an asteroid led to the extinction of dinosaurs by constructing a food web from the prehistoric era. The resource offers comprehensive background information through videos and explanations and all the materials can be found at home (including 3 printable templates). Given the complexities behind ‘constructing the web,’ moderate adult support is required with building connections between species (by interpreting descriptions on each card). Not only do students learn about the relationships in food webs, but also the causal hypothesis behind the extinction of dinosaurs using deductive reasoning of the data presented.
