Miss Bourkes Class blog

​We have been very busy in Ms Bourke’s room over the last few weeks in particular with science club which finished up this Tuesday. In our first week we learned all about sound and how it moves in vibrations through molecules. We played with boom whackers and other fun instruments. The next week we made guitars and lava lamps. With our lava lamps, we used Alka Seltzer as a catalyst to make two immiscible liquids move. We learned that a catalyst is something that causes a reaction, and immiscible liquids are two liquids that do not mix (oil and water). In the third week we learned about viscosity, and had a viscosity race between thick and thin liquids to see which had the lowest viscosity. We poured honey, water, paint and oil down a table on its side to see which would travel the fastest. The water won which means it had the lowest viscosity. In our final two weeks we learned about optical illusions, but perhaps the highlight of the whole science club was this week when we made puking pumpkins and did a lung test. We put baking soda, food dye and vinegar into pumpkins which caused a reaction and made liquid spew from their mouths. We all had so much fun and hope to do it again next year.
