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...

Students find the mass, volume, and density of various objects. In this density measurement lesson, students observe how same-sized objects can have different masses, then use water displacement to find the density of each object and...

Students explore the concept of density. In this density lesson plan, students determine the density of various objects. Students use the density of the various objects to predict the density of various unknown solutions.

Middle schoolers explore geometry by completing a physics activity on-line. In this mass measurement lesson, pupils define the terms mass, volume, and density and identify their relationship with each other. They complete an on-line...

Young scholars investigate what matter is and how it changes states.  In this physical properties lesson, students examine the vocabulary database and identify the characteristics of the three phases of matter.  Young scholars...

Students compare Jupiter and Earth. In this Earth and space studies lesson, students compare the composition of Earth and Jupiter and analyze how the composition affects the rate at which the planets spin.
