Document Summary

Observation is the act of viewing the world around us. Experimentation is a disciplined and controlled way of asking and answering questions about the world in an unbiased manner. Observations allows us to draw tentative explanations called hypothesis. Darwin appreciated that selective breeding is successful only if specific features of the animals can be passed from one generation to the next by inheritance. argued that life has evolved over time by means of natural selection. A hypothesis makes predictions that can be tested by observation and experiments. The scientific method is a deliberate and careful way of asking questions about the unknown. The living and nonliving worlds follow the same chemical rules and obey the same physical laws. The first law of thermodynamics states that energy can neither be created nor destroyed; it can only be transformed from one form into another.
