Students examine the bacterial expansion pattern and attempt to relate what they discover to expanding powers of two. They also relate what they see and discover to increasing living space requirements in a world of infinite space and finite space to discover that living space decreases as a function of one over expanding powers of two. The…

Teachers can use pedometers to facilitate inquiry learning and show students the need for mathematics in scientific investigation. The authors conducted activities with secondary students that investigated intake and expenditure components of the energy balance algorithm, which led to inquiries about pedometers and related data. By investigating…

In this activity students examine burrow casts to learn about burrowing animals and practice their math skills. Students compute the volume and average circumference of a burrow. They also determine whether a relationship exists between burrow volume and the size of the organism that created it. Students use science as inquiry as they analyze and…
