Students explore a hydrometer.  In this gravity lesson students construct a hydrometer and create a liquid density column. 

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

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

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...

Students identify and complete activities about the structure of the Earth. In this Earth structure lesson, students view a Powerpoint about the Earth's layers and complete a diagram. students compare temperatures in the Earth's layers...

Students use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and create a...

Students investigate crude oil. In this crude oil lesson, students investigate fractional distillation and use this technique to separate two liquids.

Students comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...
