Experiments with Chemical Changes at Waimea College

Mapua has a bang at Waimea!

On Thursday 15th Room 5 were on the road to Waimea College to have a very special science lesson......

Room 5 met the science teacher. His name was Paul Croskey and he taught the older students of Waimea College. The first 10 minutes was wasted on a safety instuction and Room 5 started to get restless. All they wanted to do was to blow up things!

But then the real fun started! They had to listen closely to the instructions and watch out - if any drops fell on their hand it would burn. One of the acids Room 5 used was hydrochloric acid.

Near the end of Room 5’s lesson, they got to do what they wanted to do KABOOM!!! Yes they got to blow up an egg! Libby got the pleasure to not only hold a flaming stick but also to be blasted in the face by eggshell! There were two holes, one at the top of the egg and one at the bottom.Then Paul put acid in the in the bottle and stood back while Libby looked around nervously. We waited and waited and waited. Nothing happened so Paul did the same procedure and this time.....KABOOM!!!! We were shot by eggshell and Libby seemed a little shocked to say the least! After that we were to go back to our cars and drive to school after a cool afternoon doing science at Waimea College.
