Hello,
I think that specifics would depend on what grade level you end up teaching. I have found that the Sci-Packs offered here on the nsta site are great resources for a refresher on specific topics. Some will offer more information than you might need but it is great information. Also, I recommend seeking out the curriculum that you are going to teach and researching specific topics thorugh videos. There is so much information out there and on here! I love the journals that nsta puts out. I have the hard copies and have saved them as resources to use in my lesson planning. Good luck!
