Find out what variables are in a scientific investigation and what the difference is between an independent, dependent, and controlled variable. Look at samples of different types of variables and find out what makes a good variable.

This lab activity will have students crushing crystals to learn about variables and the importance of controlling those variables. Lab activity includes student and teacher instructions.

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

An activity where students try to optimize profits by producing the largest daily output of ammonia by simulating the Haber-Bosch process. Students will use their knowledge of equilibrium reactions and the effects of variables like...

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

The purpose of this activity is to bring together the students' knowledge of engineering and airplanes and the creation of a glider model to determine how each modification affects the flight. The students will use a design procedure...

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

The purpose of this activity is to use a scientific method to determine the effect of control surfaces on a paper glider. The students will construct a paper airplane/glider and test its performance to determine the base characteristics...

In this instructional activity, students will learn about kites and gliders and how these models can help in understanding the concept of flight. Students will design and build their own balsa wood models and experiment with different...
