Hi, Janie! I am an elementary education pre-service teacher at Wartburg College and I actually just did some research on the website called phet.colorado.edu. I really enjoy this website because it is extremely interactive through its multiple simulations. There are so many simulations that there are opportunities for labs from kindergarten all the way to undergraduates! PhET simulations can be chosen from their website and utlized however best fits your classroom! I think that it is definitely a fun way to get minds going in an online environment! It is also a great way to show students real-life connections through the simulations they offer.
