Floating Rock Pets – Science, geography & art!! (Louise)

How cute!!

Floating Pet Rocks

We are very lucky to live so close to the ocean – we often go for walks along the coastline and visit our local tide pools searching for animals.

Today my 4yo Daughter found a lot of rocks along the shore – she asked if we could make them into some rock pets, a craft we often do with random rocks she collects (as Jenni made here -http://wp.me/p2Uher-1Jw).

Little did Miss M know that she had collected a different kind of rock today – Pumice Stone. I thought these would make a FUN addition to our pet rock family – Floating pet rocks!

Floating Rocks

This ended up turning into a great science experiment – we tested them against normal rocks in a clear jar filled with water. The regular pebbles sank straight to the bottom however the Pumice Stone floated every time.

Discussion points
Do the rocks look similar?
