Please help PhET and donate before the end of the year!

A BIG thanks to those of you who have donated!

For those of you still considering to donate before the end of the year, here’s what we’ve done in the last year. PhET has:
– published 15 new sims including Build an Atom, Bending Light and Gravity and Orbits
– initiated teacher professional development webinars that we offer for free
– continued our research to advance effective simulation design and use, expanding to middle school grades
– began planning a new teacher support system which will include videos of exemplary sim classroom use, more teacher activities and concept questions
– expanded PhET usage to over 25 M sims per year around the world (~65% growth from the previous year) and increased our translated sims to over 64 languages

PhETsims will always be free, but we need your help.
Support PhET during our annual campaign.
