• Examples: Botany, Zoology, Ecology…

• Can you name any other fields?

Biology, Technology, and Society• Technology: is the use of science to

solve everyday problems.

• It is often called applied science.

• Biology can be used to solve everyday 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. Organize & Analyze Data

7. State a Conclusion
