  1. Hi, my name is Grace, this is really helpful thank you. :)

  2. There seems to be a problem with most of your videos they aren't showing up.

    1. Hi, do you mean on this particular post, or on the site in general?
      I do see the one about the Doppler Effect is not working and will remove it now... The rest will play for me. I did need to click to update the Adobe Flash player...
      And as for any other videos on other posts... I'm sorry, but this site has pretty much been inactive since 2014, when my last child graduated. I've left the site up for others to use as they are able.
      While I'm aware that there have been some videos on various posts on the site that do not work, I haven't had time to keep up with removing them as more stop working at any time, without my knowledge.
      Thank you for understanding. =)
