There are so many different facets to it and so many different ways to incorporate the teaching of science into the students everyday life. Science is the knowledge we gain about things we don't understand. We make predictions and test what we think is true in order to obtain more knowledge. We then find ways in which to apply that knowledge to every- day life. Basically, I guess what I am saying is that science is knowledge although knowledge is not necessarily science.
Science is the process of finding answers using logical, systematic processes and steps.
I really think that science helps kids to question themselves and to observe and to utimately predict outcomes. Science allows kids to take risks that they may not be comfortable enough to take in other subjects. I think that the question should have been what is not science. I have found that for k-3, and probably the older students too, science can be anything. Just like you are having us bring in any materials that we want, I am finding that there is a lesson to be taught in everything.
