Verify the rule of thumb for finding the time of death. The project-based learning task asks pupils to determine when the rule of thumb process of finding the time of death is appropriate. Learners develop a function for the rule and graph it. Using information about the ambient temperature, they determine how long the rule is valid.

Instructional Ideas

• Conduct a short lesson on solving a piecewise function for a specific value
• Lead a discussion on the scale that would be appropriate for the graph

Classroom Considerations

• The class should be familiar with graphing piecewise functions

Pros

• Includes scaffolding resources to assist with technology solutions
• Contains a reference handout on piecewise functions

Cons

• None
