Today, we learned that science is tentative. Tentative means that ideas and theories can change when we gain new knowledge. One example of the tentative nature of science is the classification of Pluto. Several years ago, Pluto was known as the ninth planet in our solar system. We read an article in class today (Pluto Article) that explains how scientists recently determined that Pluto would no longer be considered an actual planet. There are many more examples of scientific theories being revised or even completely thrown out;
Copernicus - discovered that the earth was not the center of the universe.
Germ Theory - believe it or not, there was once a time when surgeons didn't wash their hands between patients.
Now that we are familiar with the six requirements of science, we are almost ready to start actually doing science! But first, a quiz! If you need help reviewing (or lost the study sheet I gave you) click here!
Have a great 3-day weekend!
Go Bulldogs!!
