Density
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...

Mass Measurement
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...
Curated OER
Mass, Volume and Density
Students compare and contrast the mass, volume, and density of various objects. They use a triple beam balance, measure and record the volume of a cup of water, and discuss the results.
Curated OER
Mass
Students participate in a qualitative discussion of the distinction between weight and mass, followed by a description of astronaut mass measurements in a zero-g environment.

Activity #7 Mass, Volume and Density
Students comprehend that density depends on the type of material and not on the amount of material. They use a spoonfl of table salt and a box of table salt and have the same density. Pupils comprehend that density is calculated by...

Let's Measure
Third graders practice measuring different objects. They discover the concepts of ratio and proportion and practice converting numbers into the correct unit. They read stories as well to help them with the concepts.
Curated OER
Density Lab Activities
Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.
