Even though school’s ending, PhET will be hard at work over the summer upgrading the simulations for the new school year. And, right now, user donations are our key source of funding towards converting simulations to HTML5 and bringing them to iPad and Android tablets. So please help support our summer vacation work and give the gift of learning.
Donate today. And, thank you to those of you who have already donated. Your support will help keep our work funded through the summer.
