Just a TON of stuff has come across my social media sites lately about science (assuming because of the science standards). Here are few GREAT links that provide lesson plans/activities you may enjoy for science!
http://www.scienceofeverydaylife.com/teachers/ = lesson plans/activities for all grade levels
https://phet.colorado.edu/en/simulations/category/new = GREAT interactive science simulations for students of all ages!
http://www.youtube.com/user/BrainStuffShow?feature=watch = "How stuff works" You Tube Channel that has really neat, interesting videos on how stuff works . . . I was enthralled with some of them, and they are quick.
