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.

Students 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.

This open-ended boat building exercise is meant to be part of a three-lesson plan 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...

Learners 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...

Middle schoolers investigate crude oil. For this crude oil lesson, students investigate fractional distillation and use this technique to separate two liquids.

Pupils 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. pupils compare temperatures in the Earth's layers to...

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...
