Just when you thought PBS’s NOVA couldn’t get any cooler – they come out with labs! NOVA Labs offers three labs (Sun, Energy and Cloud) with more on the way. Each lab is an interactive research program using real data and asking real questions. There are videos to give you the background information that you need and you can create an account to track your progress. They even have related career information for each subject. Educator guides are available for each lab and link to lesson plans and other resources. Suitable for middle and high school students. Totally free.
