Humans have never laid eyes on these creatures, so how do we know about them?
How did they come to be, and why are they not around today?
What was Earth like millions and even billions of years ago?
Rather than the adults making the volcano - we had our children create dinosaur land
from scratch! We put out a large heavy piece of cardboard, some chicken wire twisted
into a basic island/volcano shape, newspaper and PVA glue. Children covered the whole
lot with torn-up newspaper and glue (using their hands to smooth it down) and the only
instructions given were to explain that they needed to leave a hole in the top of the
mountain. After many layers of paper had been glued on, we left it to dry for several
days. After looking at pictures of islands and dinosaur landscapes - we put out green,
brown, blue, red and white paint. Children applied colours as to where they thought they
should go and what we finished up with was a terrific play mat - complete with the cotton
wool smoke coming from the top of the volcano (they insisted on this!). We used this for
many weeks with our model dinosaurs - and by putting a small container into the
volcano, they could make it erupt to enhance the play. We still have the playmat and
intend giving it to the children, this year, to recover and start the dramatic play all over
again. Parents were most impressed when their children could explain, in detail, all about
islands and volcanos - and make suggestions as to why dinosaurs disappeared.

In our pre-K and Kindergarten classes, I have to admit that we all love our dinosaur days
and we introduce the concept of fossils into the classroom. First we collect a variety of
bones saved from meals in all households. I boil and clean the bones, and then they are
laid out to dry (while the kids try to guess where they had come from. Then we cook up a
batch of plain white playdough, let it cool and knead it smooth. The children then take a
bone, place it inside of a lump of playdough, make sure the bone is completely covered
by the dough, and put it on a cookie sheet. We then slowly bake the dough (it can be air
dried, but it takes forever!) until it's "rock" hard. The children then use a variety of
instruments (experimenting along the way) to try to break the rock, use big bristle
brushes to remove the dust, and slowly but surely, expose the bone and see it's imprint in
the playdough. It's a great adventure for them to play paleon- tologist and to try to guess
which bone they're uncovering as they go along.
