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...

Log some practice with logarithms. A PowerPoint presentation provides a tutorial on the change of base formula involving natural logarithms and solving exponential equations with logarithms in the fourth installment of a seven-part...

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...

A neat handout immerses learners in the history of canoe making. After reading, small groups of mini engineers work to craft a canoe that will not be immersed! This is an ideal exercise in engineering design for your STEM curriculum or...

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.

Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

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

It may be time to get to know the skeletons in your family. The first lesson in a series of 5, introduces the class to the concept of osteoporosis. The class members brainstorm possible causes and whether the family should be concerned...

Sixth graders investigate the livability of different planets in the universe by researching and organizing information from a number of sources in this unit project. They decide on a location for a space station which they support in an...

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.
