This is the website that we check daily August through early October for hurricane activity.
You can look up any National Park, Monument, or Historic Site on this website.
School tube is a great alternative to You Tube. It has many of the same videos but is designed for school so it is safe for kids of all ages. It has experiments, videos, etc. for all subject areas and all grade levels. I have used this to show Bill Nye the Science Guy videos. We did not get to Forces of Motion and also Light/Sound yet.
This website has lots of different experiments for kids (and adults). I have used this site in class. I have saved it to the page for experiments to do at home. Enjoy exploring.
This is NASA’s official webpage and this link takes you to activities to do at home.
