Observe changes to electrostatic force as you play with the distance between charges and charge amounts at both macro and atomic scales.

Play with John’s foot and arm to explore when he gets a zap!
Observe changes to the equation and wire as you play with the resistivity, length, and area sliders.
Build sandwiches, then investigate molecules to explore reactants products and leftovers. Note this sim does not yet have a Keyboard Shortcuts dialog, and simple descriptions are in progress.
What is concentration? Explore the relationships between moles, liters, and molarity by adjusting the solute amount, solution volume, and changing solutes to compare different chemical compounds in water.
Drop balls to begin observations. Note this sim does not yet have a Keyboard Shortcuts dialog, and simple descriptions are in progress.
Grab a balloon to explore concepts of static electricity such as charge transfer, attraction, repulsion, and induced charge.
Stream alpha particles to begin observations in Rutherford’s experiment. Note this sim does not yet have a Keyboard Shortcuts dialog.
Visualize the gravitational force that two objects exert on each other. Discover the factors that affect gravitational attraction, and determine how adjusting these factors will change the gravitational force.
Visualize the gravitational force that two mass spheres exert on each other. Move spheres in meters, change mass in kilograms, and observe changes to the gravitational forces that m1 and m2 exert on each other.
Grab the Chemistry to play and explore concepts related to friction. Note when using the VoiceOver screen reader with this simulation it is easy to activate VoiceOver's Quick Nav mode while moving the Chemistry book. For the best experience, however, we recommend keeping Quick Nav off.
Play with voltage and resistance sliders and observe changes to the equation and circuit.
Turn light source on to explore. Observe what happens in the observation window as you set up different combinations of light source and molecule. Note this simulation is the first to support our zoom and magnification feature, so zoom in for a closer look, if you need to.
An early exploration (2015) into how to make a sim accessible has taken place for Capacitor Lab Basics. The sim is keyboard navigable with some auditory descriptions when using 'Forms' mode with a screen reader. We are working on updating the content and the interactions, so that the simulation can be accessed by a screen reader in any mode. This prototype has been tested with NVDA and Firefox.
An early exploration (2015) into how to make a sim accessible has taken place for Forces and Motion Basics. It has working keyboard navigation and auditory descriptions for the 'Net Force' screen when the screen reader is in 'Forms' mode. We are working on updating the content so that it can be read by the screen reader in any mode. Notes for the main interaction: Press 'Enter' or 'Spacebar' to enter a group of pullers. Once in the group, use 'Arrow' keys to choose which puller you wish to select. Press 'Enter' or 'Spacebar' to select puller and move to knot selection. Use 'Arrow' keys to choose between different knots. Press 'Escape' to leave a group of pullers or knots, 'Tab' to leave group and go to next element. This prototype has been tested with NVDA and Firefox.
Who are the biggest super stars in the universe? For Adam Burrows, an astrophysics professor at Princeton University, it's not who, but "what," and they are far from Hollywood, or even Earth, for that matter. Burrows reveals that the biggest super stars are the stars that die in a massive explosion called a "supernova." With support from the National Science Foundation, Burrows investigates supernovae, and he has recently created 3D computer simulations showing the actual moment of a star's death. His simulations are revealing more about these stellar performances.
Part of the Project-Based Inquiry Science "Earth Science Content Videos" series. Modules include the following: "Mantle Simulation: Hot Water in Cup," "Mantle Simulation: Cold Water in Cup," "Mantle Simulation: Cardboard," and "Plate Interaction Animations."
Real satellite imagery, as well as simulations, explore how Earth's moon has changed over time. This video looks at how the moon likely formed about 4.5 billion years ago, how impacts from large objects formed craters, and how additional impacts from smaller objects continue to cause cratering.
Three aerospace engineers explain how they work with experiments, simulations, and wind tunnels to improve aeronautics. This segment also discusses Ohio’s unique contribution to aviation history, from the airplane to the moon. Part of the "Career Connections" series.
In a year when many Floridians have experienced first-hand the dangers of raging wildfires, University of Central Florida researchers are preparing to study whether interactive, virtual reality simulations of wildfires can make residents more willing to invest in preventing them. With funding from the National Science Foundation, the UCF research team is developing an interactive simulation of a wildfire spreading through Volusia County. Participants will decide how much they want to invest in prescribed burns and insurance, and their decisions will be contrasted with those who only receive written information about the danger of wildfires.
