This is an Amazing resource for modeling science topics with simulations! Run by the University of Colorado at Boulder, there are tons of interactive simulations including ones I've used in my classes that are very helpful in visualizing certain topics. The website also has shared activities from teachers across the country including lesson plans, homework, demos, and labs for all grade levels!

This is a site run by the UIUC Department of Physics and their outreach program The Physics Van. Although this is focused more towards the elementary level, it is still a good source for Q and A about physics topics.

This is another portion of the talking science website. It is a sort of video blog that interviews unique science related jobs. This is a good source to show students to get them interested in the science job world.

Talking Science is a great resource for Teachers Parents and Students. The Teachers section has activities and even lesson plans from all disciplines to use or draw ideas off of.

sciencefriday.com is a website for a National Public Radio show about science. It updates about every Friday and has cool science stories that relate to all walks of life as well as correspond to current events. There are often great videos to go along with some stories.
