Learn why different materials of different sizes float and sink with the new Density sim. Why do objects like wood float in water? Does it depend on size? The Density sim has a set of great teaching ideas with pre-lab, post-lab, teaching notes and sim activities to help you through your lesson plan.
Preview the newly released Capacitor Lab sim Version 1.0. Change the distance between the plates, add a dielectric, then measure the electric field and voltage.
Note: this simulation is “Under Construction.”
The entire PhET website is now available in Greek and Brazilian Portuguese. Look for more languages to come.
Try out our new Acid-Base Solutions sim. Use lab tools on your computer to find out how strong and weak acids differ. Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity.
