Combine the math skills of graphing with the scientific method! A hypothetical situation presents itself when a student makes quantitative observations about the class lizard and the number of crickets that get eaten each day. Students have to make a bar graph using the data collected. They add labels and numbers to the graph to make it complete. On the second page, students answer questions about the graph and explain how they got their answers. The final question asks them to make an inference about the data by explaining why the lizard ate fewer crickets on Days 2-5 than he did on Day 1.
