Students determine the density of different substances. For this physical science lesson, students rank them according to their density. They discover the relationship between volume and density.

Young scholars investigate why some objects float or sink in water. In this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.

Students compare the densities of different liquids. In this liquids lesson plan, students compare color, viscosity, weight, volume, and graph their findings.

This open-ended boat building exercise is meant to be part of a three-lesson series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat, find its load line...

Oceanography experts use candy to construct a model of a bio-physical mooring that would test a variety of factors. Each piece of equipment to be included on the mooring is described within the write-up. As pupils gather the candies for...
