This site is perfect for children K-2 through 3rd grade. I stay home with my child. We are making a book of animals. Each day we do an animal with the letter we are working on. We have done A-N (a was alligator, b was butterfly, c was chimpanzee, etc.) My daughter is 2 and a half. The information is just enough to give a great overview of each animal and printouts for her to color. Altough she doesn't understand everything now, it will be an awesome resource as she gets older. She will know that she helped to do all the glueing, coloring, and put stickers on our pages. This site has taught her so much already. She told my husband last week that caterpillers turn into butterflies when they get older. This site isn't an encyclopedia for adults, it is a site for children to get an understanding of each topic. It also is a wonderful teaching tool for parents and educators alike. $20 is nothing to ask for all this information. I would spend atleast that in just coloring books, not to mention books on each animal. If you are just using this site once or twice then you need not pay. But if you use it everyday like my daughter and I do, then you should happy to support this couple's efforts to offer education to everyone. If you can't afford it, you aren't asked to pay.
