We learn from our direct experience, but we also tend to extrapolate from several experiences and draw conclusions. Sometimes these conclusions are wrong. They become embedded in our stream of consciousness and are difficult to dislodge.
For example: Children see that snow and ice melt as the weather gets warmer. They also see that snow and ice melt when we put salt on the sidewalk. They might draw the logical, but erroneous conclusion that salt warms the snow. This is wrong. The reason that salt melts ice is that it lowers the freezing point of water.
The Scientific Method helps dispel misconceptions. My next video will test the hypothesis: Salt melts ice becomes it raises the temperature, or warms, the ice.
