If you teach science, technology, physics, or any sort of STEM type learning, these games might be some fun or interesting ones to try. I have not tested them out, but there are many to choose from and they all will get kids using their STEM knowledge and hopefully get them more interested in these subjects. Everything from building a bridge to making solar cars race virtually, this game site has lots of options. Test some out or better yet, have some students test them out. Good luck.
