I hear, I forget…. I see I remember… I do, I understand

Engineers and scientists can each study biology. Yet, the
Ultimate purpose for this study is different for the two groups

The process of science
.
Observations are made and from those a question is formulated.
A hypothesis is developed that is the expected answer to the question.
Experiments are designed to test the hypothesis and predictions are
made as to what the results will be.
These predictions are testable using mathematical equations (statistics).
The experimentation begins and the results are evaluated by the
statistical methods to determine whether the hypothesis was valid.

Expectations for Biological Engineers :
1. The knowledge of biological principles and generalizations
that can lead to useful products and processes.
2. The ability to transfer information known about familiar
living systems to those unfamiliar.
1. The ability to avoid or mitigate unintended consequences of
dealing with any living system

The Chemistry of Life
Biology is the study of life
30 million types of organisms
Organisms use similar building blocks
Living systems have a hierarchy
(non-living) Atoms molecules cells (living)
multicellular organisms
Atomic composition of living organisms
6 major elements Ð Oxygen, Carbon, Hydrogen, Nitrogen, Phosphorous,
Sulfur

The reactivity of atoms arises from the presence
of unpaired electrons in one or more orbitals of
their valence shells.
