University of Colorado: Ph Et Interactive Simulations: Alpha Decay

Watch alpha particles escape from a polonium nucleus, causing radioactive alpha decay. See how random decay times relate to the half life. Java required.

Watch beta decay occur for a collection of nuclei or for an individual nucleus.

Test the pH of everyday liquids such as coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Investigate how adding more of a liquid or diluting with water affects pH.

An interactive simulation that teaches about molecules, photons, and absorption by exploring how light interacts with molecules in our atmosphere. Through this simulation students can get a better understanding of the importance of the...

An interactive simulation will heat, cool and compress atoms and molecules. Watch as they change between solid, liquid and gas phases. Recognize that different substances have different properties which will affect the temperatures for...

An interactive simulation that teaches about gravitational force, circular motion, and astronomy by manipulating the sun, earth, moon, and a space station to observe the effects of gravity and orbital paths. This simulation can either be...

An interactive simulation with weights and scales that teaches about balancing chemical equations and conservation of mass. This simulation can either be downloaded or played online and includes handouts, lesson plans, and additional...

An interactive simulation with balloons and a sweater that teaches about static electricity, electric charges, and electric force. This simulation can either be downloaded or played online and includes handouts, lesson plans, and...

An interactive simulation that teaches about Beer's Law, solutions, concentration, spectrophotometry, and more through observations to explore how much light is absorbed and transmitted with changes in thickness and color. This...

An interactive simulation that teaches about blackbody, sun, light, and quantum mechanics. Students learn my making observations while changing the temperature with a sun, a light bulb, an oven, and the Earth in order to see the changes...
