Lesson plan with mulitmedia links in which students identify and control variables to help design a solubility test for different liquids in water.

Students identify and control variables to design an experiment to see whether the temperature of a solvent affects the speed at which a solute dissolves.

This economics lesson explores what influences producers to supply in regard to demand. It examines fixed and variable costs, how such costs can be reduced, and how they influence production. Includes printable worksheets.

Conduct an investigation collaboratively on the effect of force applied on an object to produce data to serve as the basis for evidence, by using fair tests in which variables are controlled and the number of trials are considered.

This lesson teaches the engineering method for testing wherein one variable is changed while the others are held constant. Students compare the performance of a single paper airplane design while changing the shape, size and position of...
