Seventh graders discover the definition of density through a demonstration using ethanol and ice cubes and a class discussion using a SMART Board to illustrate formulas and calculations. Students finish the lesson by practicing...

High schoolers describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas,...

Students investigate the density of liquids. In this geometry instructional activity, students calculate the volume and differentiate between volume, mass and density. They observe similarity and differences between coke and diet coke.

Learners identify and describe the building blocks that make up an atom. They also compare the ages of atoms to the ages of the materials they compose,as well as, give examples that illustrate the small size of atoms.
