The Jefferson Lab Science Education site, iPad and chromebook friendly, contains resources for the teacher and student, including loads of games and videos, to assist with the physical science classrooms.
Games can include Element Hangman
Or Speed Math Deluxe.
Another video series hosted at Jefferson Lab is Physics Out Loud containing 1-4 minute videos regarding many explanation of common words used in nuclear physics research.
If you are interested in hearing a 40 minute lecture from highly credible scientists, check out archived science lectures from as far back as the early 90's. Many interesting topics to choose from.
Again, a nice collection resources to help students learn and review physical science concepts.
