In this interactive learning module, students focus on the structure and function, metabolism, reproductive processes, and biological importance of viruses, prokaryotes, fungi, and protists.

Through informational text, practice problems, interactive animations, and video clips, studentl learn more about the amazing life of plants and how they function pretty well in their generally sedentary life.

This unit focuses on the unique structure and function of both invertebrate and vertebrate animals. Students review their understanding of animal diversity, and take a closer look at the various organ systems found in the animal kingdom.

An introduction to the College Board's AP Chemistry course, which is designed to be equivalent to a first year college chemistry course.

In this module students explore how matter is classified, the history of atomic theory, subatomic particles, modern atomic theory, electron configuration, the periodic table and its trends, and spectroscopy.

Students apply new knowledge of the elements to name and write chemical formulas, write and balance chemical equations, and perform mathematical calculations about the relationships between those chemicals, using a fundamental unit in...

In this module students explore the properties of chemicals with covalent and ionic bonds. Students learn that there are different types of covalent bonds, polar and nonpolar, and that the type of covalent bond along with the shape of a...

Students discover intermolecular attractions between neighboring molecules. These intermolecular attractions, or IMA, affect the behavior of liquids, solids, and solutions.

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.

In this module students learn the relationship between energy and chemical reactions, and understand the difference between energy, heat, and work. They perform calorimetry calculations, and study the laws of thermodynamics, enthalpy,...

In this module students learn more about oxidation-reductions and how to balance these reactions and perform stoichiometric calculations on these specific reactions. Students also explore electrolysis, galvanic cells, reduction...

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....

Through a variety of activities, students learn that not all acid and base reactions go to completion, and instead, they establish equilibrium. Acid-base equilibrium expressions have their own constants, ka and kb. Students will perform...

This study guide will help students prepare for the final Advanced Placement Chemistry exam in May.

Students take a journey through our physical world, beginning with the ways in which people quantify and model mathematically the existence and interaction of physical objects.

Using only two of our fundamental units, time and displacement students will build a framework to predict the motion of objects, starting with one dimensional motion.

In this interactive tutorial, students are introduced to motion in a second dimension, and model and predict the more complex motion of projectiles.

Newton's three laws are deceptively simple, but they are the underpinning of all of physics and govern the mechanics all of your actions in everyday life. Take an in-depth look at these laws in this learning module.

Students apply Newton's laws to more diverse physical settings where multiple forces from varying origins interact. To aid in condensing the physical setting into mathematical expressions, the free body diagram is used in this module...

The mathematical model for the relationships between work and energy serves to model physical problems and, more importantly, predict natural and man-made phenomena. Students discover the relationships which serve as a powerful...

This physics tutorial aims to model and predict not the motion of just one object, but rather what happens when two or more objects collide. The concept of momentum will be the main focus of this module.

This module is the introduction to model rotational motion. All of the concepts are conveniently recast into forms that have the same mathematical forms as their translational counterparts.

Students learn about the Newtonian mechanics principle of conservation of angular momentum and the application in the quantum mechanical world.

Combined with aspects of circular motion, students discover that Kepler's third law follows directly from the law of universal gravitation. This unit will expand upon the conservation of energy principle for problems beyond the confines...
