Now, I know where that sound came from. It was a rock saw, which cuts the cores into two halves. Look I’m standing on the halves and I can actually see what is inside these rock cores. These two scientists here, Julie Prytulak from Canada and Akira Ishikawa from Japan, make observations about the different rocks. Do you know what an observation is?
Hey! I heard you have a special guest in class today, Mr. Moore, the superintendent. Maybe he knows what an observation is?
Hey Julie, can I help you? I brought my hammer with me.
Oh Stanley, that is so sweet of you, but you know we don’t need a hammer to look inside these rocks. We use microscopes for that. Come on I’ll show you one.
