The relationship between mass, volume, and density is explored using chocolate. The mass and volume of solid chocolate bars, liquid chocolate, and small chocolate pieces are determined and used to compute density for comparison. The activity includes a worksheet that allows students to report their findings and infer density changes as a material goes from solid to liquid to gas.

The Atlantic Coastal Plain tour is part of the New York Landscape Regions Collection of Google Earth Tours, created by a group of New York State science educators. This tour introduces students to glacial erratics on Long Island, the Ronkonkoma terminal moraine, and the Rock Hill erratic. Coastal erosion and deposition can be studied by viewing dunes, beaches, and wave cut banks.
