Bubs recently read a book about volcanoes at his friend's house. The next day became volcano day. We made a vinegar and baking soda volcano as well as a flour volcano. We watched clips of volcanoes erupting. We studied and colored a diagram of a volcano. Seriously, with a library and the internet, one can learn anything and everything.
Books open our minds to new ideas, stretch our brain power, and help us become greater than we could otherwise be.
