Simulations to show students the nature of chemical bonds. Simulations include an explanation of stereochemistry, atomic orbitals, chemical polarity, formation of an atom, and a summary quiz.

A collection of simulations representing concepts discussed in a mechanics unit of physics.

Simulations that can help students visualize and understand concepts in chemistry like the collision theory, chemical reaction equilibrium, and polymerization.

A series of virtual experiments that show students the power and importance of evaporation.

Explore some virtual experiments on gases and vapor pressure, the Maxwell speed distribution, the barometric formula, and heat and temperature.

See how gas, liquid, and solid molecules react to external pressure in this simulation. Also see a model of intermolecular motion through elliptical particles.

View an animation of a ladder falling due to the force of gravity.

Watch how micelle formation changes in a solution with water compared to a solution consisting of oil.

Interact with lipids and see how they form a monolayer in water and oil.

Observe the animated model to see DNA being replicated.

View the interactions between an atom of xenon and a buckyball when they collide.

CODAP is a free, easy-to-use data analysis environment for students. Students can load their own data into an easy-to-use web-based data analysis tool to create their own datasets, share visualizations, and discover data-driven insights....

Exploration of models of electric field to explain how charged objects interact with other objects via simulations, practice and activities. Sponsored by Concord Consortium and the CREATE for STEM Institute at Michigan State University.

Transformations of linear functions, with links between the symbolic and graphic forms, can be powerful tools to help students overcome conceptual hurdles in algebra.

The Function Analyzer allows learners to see the connections among three representations of a function: symbolic, area, and graphic. In addition, by allowing learners to change the value of four elements of a function - the coefficient...

The Quadratic Transformer was developed to support the learning of quadratic functions, and in particular to help you understand the connections between symbolic and graphic representations. Indirectly, it also helps you connect either...

Deepen your understanding of systems of linear equations with the System Solver. This interactive offers unique opportunity to perform operations on a system and immediately observe the graphic, tabular, and symbolic results of the...

Plop It! lets you experiment with the concepts of mean, median, and mode (measures of center). You see the differences among them on a bar graph, as you add or remove blocks to an axis with a given range.

An investigation of how polar and nonpolar interactions affect shapes of biological molecules and their function. Modules explore the following: 1. Why don't oil and water mix? 2. Can a substance dissolve in both a nonpolar and a polar...

How does energy charge when evaporation is reversed? and What powers a hurricane? are explored in this module.
