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...

Learners discover the property of density while participating in a lab exercise. In this scientific measuring lesson, pupils utilize a scale to measure the density of different metal materials. They document their work and present their...

Students explore physical science by conducting a measurement experiment. In this mass lesson, students identify the differences between mass and weight and define a list of other vocabulary terms. Students utilize electronic scales and...

Students explore physics by conducting a class experiment. In this density lesson, students examine a list of items and discuss whether they will sink or float and then determine their density. Students examine the objects over five days...

Students explore the Law of Conservation of Matter using effervescent tablets.  In this mass and energy lesson, students investigate how mass is conserved in the reaction of effervescent tablets and water. They will discuss and...
