Well...maybe that should have said 37 degrees since we use the Celsius scale! Today was the perfect day to talk about certain 'benchmark' temperatures on the thermometer. This morning, we began by recording the current temperature (-5 degrees Celsius) on the thermometer. We talked about what we saw outside (ice and snow), and what we had to wear that morning (hat, boots, mitts). Next, I gave them the standard body temperature of 37 degrees Celsius. From there, I would suggest ideas and they would problem solve to see how close they could get to guessing the degrees Celsius. We learned that water freezes at 0 degrees, and boils at 100 degrees. We also found out that the average refrigerator temperature is 7 degrees, and that an indoor recess is usually announced at -25 degrees. We had a lot of fun guessing the new temperature on the thermometer each time we came in from recess, and found out that we had a 15 degree temperature rise over the course of the day. The students were so interested in this topic that they asked me to find hottest/coldest record temperatures for Ottawa, Canada, and the world! For the record, the hottest recorded temperature on earth was 57.8 degrees in Libya back in 1922. The coldest was -89 in Antarctica in July of '83. See our labelled thermometer below:
