Not all variables are created equal. Discover how variables in computer science are different from variables in math class. Scholars learn to work with variables in computer programming by developing a mental model for how variables...

If you need an array of worksheets to augment your science lessons, peruse a collection of assignments that is sure to fit your needs. With topics such as metric conversion, the scientific method, textbook features, research skills,...

Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...

Time to experiment with mathematics! Learners study experimental design and how randomization applies. They emphasize the difference between random selection and random assignment and how both are important to the validation of the...

An inquiry-based algebra lesson explores real-world applications of linear functions. Scholars investigate four different situations that can be modeled by linear functions, identifying the rate of change, as well as the...

How much does your class know about psychology? What about empirical evidence? If they could use some time to learn the essentials of psychology, use a quick reference sheet to note what they know before the test, after the unit, and at...

Connect the size of a rolling cup to the size of circle it makes. Pupils view videos of cups of different sizes rolling in a circle. Using the videos and additional data, they attempt to determine a relationship between cup...

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 instructional activity 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...

[Free Registration/Login may be required to access all resource tools.] This Concept introduces students to good design for statistical studies or experiments.

Students are challenged to design a way to drop a raw egg from varying heights without letting the egg break. Creative thinking and evaluation of results are critical to the project.
