Density - Mass | Volume - PhET Interactive Simulations
Why do some materials like wood float in water, and others don’t? Interact with blocks of different materials, including a custom option by modifying their mass and volume, to explore the effect on the density and discover the conditions for sinking or floating in water. Play detective to determine the material of each block by comparing its density with the values in the table.
Circuit Construction Kit: AC - Virtual Lab
Construct AC circuits with interactive simulations and explore electrical properties in this virtual lab.
Build an Atom - Atoms - PhET Interactive Simulations
Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Then play a game to test your ideas!
Virtual Lab - Series Circuit - PhET Interactive Simulations
Do you like Circuit Construction Kit: DC, but want to use only in-line ammeters? This is the sim for you! Experiment with an electronics kit. Build circuits with batteries, resistors, ideal and non-Ohmic light bulbs, fuses, and switches. Determine if everyday objects are conductors or insulators, and take measurements with a lifelike ammeter and voltmeter. View the circuit as a …
States of Matter - PhET Interactive Simulations
Explore the states of matter with interactive simulations that show how molecules form solids, liquids, and gases.
Density - PhET Interactive Simulations
Explore density by interacting with blocks of different materials, adjusting their mass and volume to see how they sink or float.
