Upper graders experiment with measurement. They estimate the length, volume, and weight of various objects, then rotate through stations making predictions concerning measurements and then testing their predictions.

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

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

Students are able to identify the components of the cardio-vascular system. They are able to describe the way the heart works to pump the blood. Students are able to explain the function of the cardio-vascular system. They are able to...

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.

Students explore electrical resistance through various experiments. In this physics lesson, students calculate resistance using a mathematical formula. They explain how colors identify the resistance value of a resistor.

Fourth graders build an explorer vehicle which they program through an obstacle course to enter the tomb or temple to discover artifacts.
