Did you know about The Happy Scientist? Scientist Robert Krampf has created a site for learners to go and explore videos and learn about many different areas of science.
There is now new units of study for Minerals and The Process of Science, Food Webs and a unit on rocks is being built out and is in progress. We can't wait till these are ready :)
The subscription is very reasonable and my youngest son love these videos~ be sure and check it out when you have a chance.
Happy science learning!
