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.

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 economics lesson plan 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.

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...

Given investigation scenarios and lab procedures, students will identify independent variables, dependent variables, constants, and control groups.

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...

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 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...

Test the efficacy of different types of hand hygiene to stem the transmission of diseases by conducting an experiment using variables and a control group.

Investigate the theory that including desert plants such as mesquite and cactus in a diet can help control obesity and diabetes. Design a scientific experiment that will test this hypothesis, using control variables, observation and...
