I think I know what is part of the problem at least where I live which is in San Antonio, TX. Do you know how many educational stores there are for our kids and students here in such a big city? There is only one store that I am aware of. And even then the educational store has only basic, grade level stuff. We used to have the discovery channel store here in our city but that is even gone.
I have spent HOURS looking for GOOD QUALITY books for my grade level child, middle school, high school and college level child and I had a hell of a time finding good quality books that make sense to a person without a pHD. I'm just a mom that wants my kids to succeed and I'm very inquisitive about many things.
But finding good quality science tools to help me and my kids understand has proven to be a challenge. Can you imagine, I'm going out of my way to do this. I know many of my friends and relatives would buy or get the science education tools if it was in front of them, but they sure hell are not going to spend the hours looking for these science tools. How can in the land of plentiful, have missing those educational opportunities? Maybe it's the town I live in?
