A Message to my Readers

I am slowly going through all past science posts, and checking videos, adding links for images, etc.
However, I may not check every link, and a video that plays today may be removed next week by the person who uploaded it, and you will get some kind of error message when you click play.
There have been times I've posted a video, and two days later one of the kids in my class tells me it won't play.  Already.  =(

So as you view my posts throughout the year, (any posts, not just science!) if there are any unplayable videos, or broken links, or links that do not link to what they are supposed to, just leave a comment on that post and let me know.
If you see any other errors, please feel free to advise me of those as well.

Thank you so much!
