With the contradictions between some so called scientific topics in the Western world what is a teacher to do ? To present science in its purest form; knowledge, means reverting back to the roots of science. Here we will talk about the roots of science and presenting this without bias to those who truly need to learn it.
Those great leaders of science, Francis Bacon, Aristotle, Galileo, and others were less interested in popular opinion than they were at arriving at the truth. They simply wanted "to know". This purity of focus is the same focus to have in the modern classroom if a teacher wants to truly teach science and the scientific method. The roots of science were simply to find out what is true. There was no hidden agenda and there were no Climategates.
The famous struggle of Galileo with the Catholics was won simply by leaving the authority of man behind and believing that truth was "self evident". Although this seems dangerous the scientific method is a method that is repeatable. That is, if it can not be repeated it is not supported by the scientific method. The scientific method teaches that observable phenomenon are to be recorded. If they are not observable, they can not be recorded. If they can be recorded, they can be repeated, which makes the scientific method trustworthy. Although this method is limited to those things that are observable or demonstrative, it is nevertheless a good starting point, a good "jumping off" point for young students. Science is not a perfect method but has the ability to create a desire to not settle for second best while exploring our world and points beyond.
If you do not have a problem leaving behind the authority of man like Galileo, you can teach science without bias. You can let the facts speak for themselves. You can use the senses you have been given to learn the truth right along with your students. This is a refreshing, liberating way to look at the world. Without discussion, the world is surely in need of refreshing, liberating ideals. It can start right there with you teaching your students. Who knows if you may have another Francis Bacon or Sir Isaac Newton in your class ? He or she may go on to discover great things through your enlightened teaching of science !
Those forerunners of science in the past were pioneering truth seekers. They studied carefully and came up with the foundations of physics, chemistry and other areas of scientific activity. They were not like the scientists of today that can be bought out by powerful people. They were willing to die for their belief that truth was achievable. If you have this same devotion to truth you will be walking in their footsteps. You will have the same effect on the world as those pioneers did, although you will be doing it to a lesser degree.
For now, the common man is leaning not to truth, but to "discovering himself" and what he believes about truth.
This attitude is to be avoided in the science class. Remember, philosophy is not "observable" and so is not in the realm of science. It has an influence on science, but is not in its own right to be classified as science. To remain unbiased you as a teacher must remain in the position of those men who pioneered such things as the laws of gravity and physics, the laws of propulsion, the laws of botany and so forth.
As a teacher, present yourself to your students as a champion of science. This means you are the champion of reality. You are simply a channel through which young people can learn what is real. In computing terms you are the database of information that comes from truth and can be accessed on many different levels. Not all students have the same learning abilities. Caring teachers are sensitive to this and present topics to the whole class accordingly. If someday you happen to hear that one of your students has accomplished great things you will know that you had a part in it. This will only come if you have accomplished great things in teaching. Do not let your bias get in the way of your teaching and let true science lead the way.
