These animated GIF images will demonstrate the effects of the various gas laws with a colorful model and graph.
This applet allows students to build atoms by combining different amounts of protons, neutrons, and electrons. The atomic number, charge, and radioactivity are displayed after each additional particle is added. Questions throughout the applet allow students to check their understanding of the concepts with instantaneous feedback.
This game has students match a picture of laboratory equipment with the correct name. The equipment mentioned in this game includes test tube holder, graduated cylinder, flask, beaker, watch glass, wash bottle, funnel, medicine dropper, evaporating dish, utility clamp, ring stand, beaker tongs, stir rod, crucible, collection bottle, test tube.
This game is like classic battle ship, but in order to successfully "hit" a target the player must correctly answer a question about lab safety.
This animation shows how varying three experimental parameters (concentration, temperature, and pressure) affects the equilibrium of a reaction.
This simulation allows students to change different variables of a reaction. They are given immediate visual feedback as to how the change shifts the reaction. A worksheet is also available.
This is an exercise in determining the oxidation numbers in ions and compounds. Calculate the oxidation numbers of all the elements using the standard assignment rules, then mouse over the formula to reveal the answers.
This animation allows students to explore the elements and various periodic trends.
With the help of Periodic Table Live! and the associated worksheets, students can explore the elements and periodic trends.
This simulator expands on the PhET Gas Laws simulator. In addition to controlling the pressure, volume, temperature, and number of particles, students can now control balloons and other objects and balance pressures inside and outside of the object.
This simulator enables students to study the microscopic interactions of gas particles and the effects of volume, pressure, temperature, and the number of particles.
Animation of precipitation reactions (double-replacement or double-displacement reaction in this animation) at the molecular level.
This quiz lets students receive immediate feedback on their understanding of metric prefixes and mixes in a little scientific trivia that utilizes prefixes.
This tutorial introduces basic laboratory equipment. It has a matching activity at the end that provides feedback on the student's recognition and naming of various equipment.
