The PhET project at the University of Colorado creates "fun, interactive, research-based simulations of physical phenomena." This particular one deals with Beer's Law. "The thicker the glass, the darker the brew, the less the light that passes through." Make colorful concentrated and dilute solutions and explore how much light they absorb and transmit using a virtual spectrophotometer! The simulation is also paired with a teachers' guide and related resources from PhET. The simulation is also available in multiple languages.

Explore bending of light between two media with different indices of refraction. …
Explore bending of light between two media with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows.
Watch your solution change color as you mix chemicals with water. Then …
Watch your solution change color as you mix chemicals with water. Then check molarity with the concentration meter. What are all the ways you can change the concentration of your solution? Switch solutes to compare different chemicals and find out how concentrated you can go before you hit saturation!

This simulation lets learners explore how heating and cooling adds or removes energy. Use a slider to heat blocks of iron or brick to see the energy flow. Next, build your own system to convert mechanical, light, or chemical energy into electrical or thermal energy. (Learners can choose sunlight, steam, flowing water, or mechanical energy to power their systems.) The simulation allows students to visualize energy transformation and describe how energy flows in various systems. Through examples from everyday life, it also bolsters understanding of conservation of energy. This item is part of a larger collection of simulations developed by the Physics Education Technology project (PhET).

Une série de simulations provenant de l’Université de Colorado à Boulder pour les 9e – 12e au sujet des sciences.
« Déplacez le soleil, la Terre, la lune et la station spatiale pour observer comment cela affecte leurs forces gravitationnelles et leurs trajectoires orbitales. Visualisez les tailles et les distances entre différents corps célestes, et désactivez la gravité pour voir ce qui se passerait sans elle ! »

Une série de simulations provenant de l’Université de Colorado à Boulder pour les 9e – 12e au sujet des sciences. Cette simulation démontre le processus du Laboratoire Loi de Beer-Lambert.
Le projet PhET à l'Université du Colorado crée des "simulations amusantes, interactives et basées sur la recherche des phénomènes physiques". Celle-ci en particulier aborde la loi de Beer. "Plus le verre est épais, plus la bière est foncée, moins la lumière passe à travers." Créez des solutions colorées concentrées et diluées et explorez la quantité de lumière qu'elles absorbent et transmettent à l'aide d'un spectrophotomètre virtuel ! La simulation est également accompagnée d'un guide pour les enseignants et de ressources connexes de PhET.
