CONCLUSION
Teachers of STEM education must know two facts. One is that the current common sense in science can be changed tomorrow. Another is that the lay public including parents does not know that known science laws may be incorrect under new observations. Scientific laws are not always true but true under the fixed conventional observations. Once scientific laws (claims) were changed, the lay public may lose trust in science. Once the public trust is lost, rebuilding trust in science is really hard. Therefore, public science policy or pubic STEM policy should be addressed: all scientific laws (claims) are temporal and they may be changed tomorrow. Today’s common sense can be changed tomorrow.
