PhET™ Labs

PhET Lab experiments represent real interactive, and research-based simulations of physical phenomena from the PhET™ project at the University of Colorado. For teachers and students around the world, the PhET project provides interactive simulations that are based on extensive education research and support more effective science education. Going beyond traditional educational resources, PhET simulations offer an intuitive, game-like environment where students can learn through scientist-like exploration, where dynamic visual representations make the invisible visible, and where science ideas are connected to real-world phenomena. Unlike most educational software, PhET simulations are free, easily translated into multiple languages, and available either online or offline, especially important for areas with poor or no internet connectivity. With their flexible design, the simulations can be used in many ways - as demos, homework, or inexpensive yet accurate and realistic lab alternatives. Explore a few of the PhET Labs simulations on several Science disciplines:

Online Activity Labs: Topics:
Plate Tectonics
Screen Shot of virtual lab
Explore how plates move on the surface of the earth. Change temperature, composition, and thickness of plates. Discover how to create new mountains, volcanoes, or oceans!

Details and get access to Plate Tectonics

Gravity and Orbits
Screen Shot of virtual lab
Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it!

Adjust mountain snowfall and temperature to see the glacier grow and shrink. Use scientific tools to measure thickness, velocity and glacial budget.

Details and get access to Glaciers

The Greenhouse Effect
Screen Shot of virtual lab
How do greenhouse gases affect the climate? Explore the atmosphere during the ice age and today. What happens when you add clouds? Change the greenhouse gas concentration and see how the temperature changes. Then compare to the effect of glass panes. Zoom in and see how light interacts with molecules. Do all atmospheric gases contribute to the greenhouse effect?

Radioactive Dating Game
Screen Shot of virtual lab
Learn about different types of radiometric dating, such as carbon dating. Understand how decay and half life work to enable radiometric dating. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.

Smart Science® Labs

Below, you will find a small selection from the Smart Science library of nearly 200 online science labs. View six labs designed for CSU general education earth/space science courses. Use any of these labs free in your courses as part of the CSU system-wide virtual lab initiative.

Smart Science real online science labs provide instructors and students with uniquely hands-on real lab experiments instead of simulations. Students collect data interactively from real experiments point-by-point using their own care and judgment just as in traditional labs. They predict or hypothesize before or during the experimental activity.

The Smart Science approach ensures that students understand the nature of science, learn scientific thinking skills, and come to appreciate the complexity and ambiguity of empirical work. Smart Science labs include quizzes and online lab reports showing all student lab data and more.

Smart Science labs are delivered in HTML5 for compatibility with all modern platforms.

Online Activity Labs: Topics:
Daily Tides

Real lab. Students observe tides in Pleasant Bay on Cape Cod for the daylight hours for days they choose that span about a month's time. The data may be analyzed for period, amplitude, and/or phase.

Real lab. Students measure time between P-wave and S-wave on real earthquake seismograms posted by the USGS. They then plot circles around the seismograph locations on a map to find the approximate epicenter. They do the multiplication of time by speed themselves and so may adjust the speed depending on distance, for example.

Basic Rock Identification

Real lab. Student see twelve rock samples, three each of igneous, metamorphic, and sedimentary, rotated, scratching glass and brass, and up close. They classify each sample.

Real lab. Various objects such as marbles, beans, metal shot, and rocks are placed in a cylindrical glass container. Equal aliquots of water are added. Students measure the height of water after each addition and calculate porosity of each medium. They look for any correlation between medium size and porosity.

Details and get access to Porosity

Erosion and Flow
screen shot of virtual lab
Real lab. Students record channel width for water flow on a sand-filled stream table for different flow rates and slope angles. They seek to understand how flow and angle may affect channel width. Other aspects of water erosion may be considered as well.
