Our 2nd Classes couldn't believe their luck this Science Week, with a visit from MSD Swords on Wednesday. Our two scientists couldn't have been nicer and we were all eyes and ears as they told us a little about the company itself and then went on to do some fun experiments. And we mean fun! To begin with, we heard how vaccines are made sterile, how tablets are measured and how medicines are checked to see if they are working properly. They are kept busy in Swords!
We looked at good hand washing and, yuk, not-so-good hand washing. Did you know 1 in 4 people do not even wash their hands after visiting the bathroom? Gross! We made a lava lamp using oil, water, food colouring and Alka Seltzers. We looked at acids and bases and used boiled-off red cabbage water as a litmus test. We tested lemon juice, baking soda, 7Up and vinegar. Finally, we made our very own balloon-inflating device. We produced CO2 to inflate the balloon by adding baking powder to vinegar. Birthday parties, here we come! We would like to thank our friendly scientists for their visit. They left us with some parting gifts and an experiment to try out using Coca Cola and a chicken bone. We can't wait and we'll certainly keep you posted on it! Check out our photos below...
