reason, the field of biology is divided
into smaller branches.


Most biologists study only

Biology, Technology, and Society


Technology:
is the use of science to
solve everyday problems
.


It is often called applied science.

problems.


The use of biology to solve everyday
problems is called
biotechnology
.

3 fields that use biotechnology

1.
Medicine




2.
Agriculture




3.
Industry

Scientific Method:


is a problem solving
model used by
scientists.


It can be broken
down into 7 parts.


However you do not
always have to use
all the parts of the
scientific method.


Every problem is
unique and needs to
be solved in a
different way.

Scientific Method:

1.
Identify & State the Problem

2.
Gather Information

3.
State a Hypothesis

4.
Design an Experiment

5.
Make Observations & Record Data

6.
