Happy Monday!
Today in Science we did a lab demo to see is salted water boils faster than "normal" (unsalted) water. We are using this demo to solidify our understanding of independent and dependent variables, as well as an introduction to graphing.
The results of the first test showed that salted water boiled first, but Mme Careen was not convinced, so she performed the experiment again over the lunch hour (with a few small tweaks to the equipment set up) and found the opposite results!
So, tomorrow in class, the experiment will once again be repeated so that we can compare results from all three tests to determine the answer to the 'age old' question: does adding salt to water really help it to boil faster? 🤔
(And don't be afraid to try this at home! This can easily be reproduced using two same-sized pots, filled with the same quantity of water, being heated up at the same heat level on the stove. We used thermometers and a stop watch in class, but, the boiling point can easily be seen by observation and the time can be controlled with a timer app on a device. Have fun experimenting!)
