Last week we conducted investigations that had you practice measuring the metrics you were reading about in chapter 1 for both Physical Science and Biology. Our purpose last week was to figure out how and why scientists use meaurement. I think our Physical Science lab spoke volumes when we reported each group's results on the smartboard. Some numbers were 750 and some numbers were 8 for the same event. It was the different units that made the numbers look so different.
So what if you are a scientist in Germany and you are working on a bacteria that scientists in America and Italy are also studying. How can you share information? How will you know what each other is talking about? How will you tell them about the bacteria you are studying in a way they can understand? They speak different languages.
The answer is that scientist have common languages they use to do this. One is the language of measurement. Scientist use the SI system of measurement so that no matter where you call home, you can understand the measurement they are talking about. SI stands for "System International". It uses the metric system when measuring in science. There are certain units all scientists use for difffferent types of measurement. For example, the SI unit for mass is Kilograms and the SI unit for length is the meter. We will learn these in class as well as practice measuring like real scientists do.
Our discussion question for the week is this: DESCRIBE how you use measurement at home AND the units you use in the measurement. An example is that I like scrapbooking and I use the English ruler measurement of inches when I measure and crop (trim) pictures for my scrapbooks.
