What a great way to start off our new topic with a pebble mystery! We had to discuss what we knew about pebbles as well as explore them to generate questions about what we wanted to find out about them. Some of the class wanted to know, What's the difference between a rock and a pebble?. Others asked Why are they all so hard? We then read part of the book 'Pebble in my pocket' to see if we could answer any of our questions. We were all amazed by the fact that many pebbles are so old and that they could originate from a volcano!
