Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...

Attracted class members to an activity-packed journey through the science behind the invisible forces at work all around us. From jump rope generators to junkyard wars, there's never a dull moment when eighth grade physics scholars...

This trigonometry textbook takes the learner from a basic understanding of angles and triangles through the use of polar coordinates on the complex plane. Written by a mathematician-engineer, examples and problems here are used to...

Only 10 percent of an incandescent bulb's energy is used to create light; the remaining 90 percent is heat. In the unit of activities, young chemists examine energy through hands-on activities, videos, discussions, and...

Students examine the roles of genes and evolution on behaviors. In groups, they identify the relationships among DNA, genes and chromosomes. They evaluate the different theories of language acquistion and how evolved tendencies interact...

Students calculate the resistance across a bank of resistors in a series, parallel and combined circuit. Using new vocabulary words, they define and describe them in a scientific manner. After stating Ohm's Law, they solve electrical...

Learning module looking at scientific explanations. Discussion covers theories and how they develop, some well-known theories and their origins, and how theories are revised and refined. Also, covers hypotheses and laws. The three...

By the end of this section, you will be able to explain how the methods of science are used to make scientific discoveries; define a scientific model and describe examples of physical and mathematical models used in physics; and compare...

Through informational text, interactive practice problems, virtual simulations, and video clips, students learn about the gas laws.

Through interactive activities in a module format, students learn about kinetics, collision theory, reaction rates, and rate laws. They will calculate rate laws from experimental data, concentration and time, and half-life of a reaction....

Use this tutorial to understand Dalton's Law of partial pressure, and then answer some interactive practice questions to review the material.

[Free Registration/Login may be required to access all resource tools.] Students will understand the difference between theories, hypotheses, and laws in science.

What is the difference between a theory and a law, and is one better? Matt Anticole shows why science needs both laws and theories to understand the whole picture. [5:12]

Resource investigates the beliefs of Dalton's atomic theory which consists of four parts. Which points do we still use today, and what have we learned since Dalton?

[Free Registration/Login may be required to access all resource tools.] Students learn about scientific explanations and interpretations through instructional videos, grade-level texts, interactive activities, and quick assessments.

[Free Registration/Login may be required to access all resource tools.] Nature of scientific laws, examples of physical science laws, and how scientific laws differ from scientific theories.

In this module, you will learn why gases are not affected by intermolecular attractions! You will also learn about the properties of gases and the math associated with this special group of matter.
