Most scholars associate density with floating, but how do scientists determine the exact density of an unknown liquid? The third lesson in a seven-part series challenges scholars to find the mass and volume of two unknown liquids. Each...

Math scholars of many ages examine the concept of population density and then discuss the significance of the population densities of Minnesota and China. They figure the population density of their school.

In this density worksheet, students review how to rearrange the equation for density to solve for mass or volume. Then students complete 4 problems.

Census-takers view the Internet to find the total population of a city and its total land area. They work with different mathematical scenarios that involve populations and land area in their city. They complete math problems and unit...

Students explore various methods for visualizing the results of hydrogen wave function. They observe trends using a polar plot tool and make plots for the first three energy levels of the radial wave function for hydrogen. Students apply...

Students are introduced to drag. Then they summarize drag by saying that the drag is proportional to the square of the velocity. Students then solve problems an example of such a problem: Explain why swimming underwater is faster than...

Pupils review the procedure for determining appropriate types of measurements for given situations and measurement conversions. They figure perimeter, area, and volume of 2 and 3 dimensional objects.
