What do logarithms have to do with bone density? Scholars learn that the equation for bone density includes logarithms. The majority of the third lesson of seven is devoted to logarithms and their properties.

Hop into a resource on Beer's Law. A PowerPoint presentation introduces Beer's law as part of calculating bone density from X-ray images in the sixth activity in the series of seven. Individuals work on practice problems with this law...

Objects may be more linear than they appear. Scholars investigate the relationship between the number of bone mineral density scanners in the US and time. Once they take the natural logarithm of the number of scanners, a linear...

Young scholars, in groups, design a procedure to calculate the mass of gas molecules in the classroom by measuring the volume of the classroom and researching the density of air. They apply changes in air density with altitude and...

Don't cast a great hands-on resource aside! Scholars learn about the process of casting by actually trying out an example. Plaster of Paris and cookie cutter molds help them complete the activity.

Fifth graders record measurements and calculate the volume. They select and use appropriate units and procedures to measure volume # use tools such as technology to solve problems

This project shows the connection between engineering, science and math by having students learn the equation needed to calculate bone mineral density. Lesson includes an explanation of the equation as well as practice problems and a quiz.
