On our adventures along our Slice of America we will see a lot of evidence of our earth's changes through its life. It is rather amazing that evidence of how our earth was formed is still visible after so many years.
PBS has a really interesting program called "How the earth was born". The series is very well done. I recorded "Birth of the Earth"and "Astroids" for the children to watch on the trip. It has a lot on geology that we will see. I will be bringing compasses and magnets for the kids too.
