On Tuesday the 26th of November, 5th and 6th class went to Ballyroan Library to learn about palaeontology (the study of dinosaurs).
We got onto the bus that the library had provided for us and left school at a quarter past twelve. We arrived very quickly. When we got there we went straight into the library and Ms. Masterson told us to take a seat. We were seated in a semi-circle and there was a table in front of us with loads of beakers full of chemicals. Then a woman came in and told us that her name was Science Sue. She asked us if we knew any dinosaur names ending in “osaurus”. A few of us put up our hands and named some. Then she asked for volunteer. Loads of us put up our hands but Naoíse got picked. Scientist Sue pulled a fluffy teddy dinosaur out of a box. It was on a uni-cycle with two weights on either side. Then she asked Naoíse to hold a string that was tied onto a coat stand and she placed the uni-cycle on the string. It didn’t fall off! The weights on the sides balanced it and it rode from one end of the string to the other.
She then asked for a different volunteer. Hannah from 6th class got picked. When Hannah was up Sue was telling us all about discovering dinosaur bones and that you had to be so gentle because they could break. Then she said that in case the real bone went missing, got damaged or was stolen, palaeontologists would make a copy. Then she said she was going to make a copy right in front of our eyes. She obviously didn’t have a real bone but she did have a tiny toy dinosaur. Sue got the toy and pressed one side into a mould. She put a few ingredients together in a bowl and asked Hannah to mix it. It finished as a green gloopy mixture and then Sue told Hannah to pour it into the mould.
After that, Sue told us a bit more about the diplodocus and then asked for another volunteer. Alex got picked. She poured some mixtures together and then asked Alex to pour one last liquid in. Then it started to bubble. She got a matchstick and lit it and then blew it out. She put it onto the foam and the matchstick burst into flames again. Sue said this was because the matchstick still contained the heat. That is why fire fighters don’t just have to get rid of the fire, they also have to get rid of the heat.
Then, Sue asked for another volunteer and Sophie got picked. In this experiment they were mixing vinegar with acids and the mixtures turned different colours depending on the strength of the acid.
Sue asked for yet another volunteer and this time David from 5th class got picked. He had to mix all the things that the Diplodocus might have eaten and then put it through a tube and all the nutrients came out because there was holes in the tube. Then he had to squeeze them all out into a bowl and that was meant to be the Diplodocus’ poop!
Then we went back on the bus and got back to school. It was home time when we got back. Thank you Ballyroan library for having us.
