The Scientific Method
Captions available
The idea
The scientific method runs from observation and question to hypothesis, prediction, experiment, analysis and conclusion; a hypothesis the results do not support is replaced.
In practice
Noticing wilted seedlings by a window leads to the question of whether heat or light is responsible.
Where people slip
When results fail to support a hypothesis, the cycle begins again with a new one.
