1. Biology as a Science

2. Biology Biology is the study of life and living things
A Biologist is anyone who uses the scientific method to study living things

3. Branches of Biology
There are many different types of biology and biologists
Each type is called a branch of biology
We will talk about 5 branches of biology

4. Branches of Biology The 5 branches of biology are Molecular level
Cellular level
Multicellular level
Population level
Global Level

5. Molecular Level Biology starts at the molecular level
Molecular biology refers to the biological chemicals
Examples :
Molecular Biologists might look at how DNA works and the chemicals that make up DNA

6. Molecular Biology

7. Cellular level
Cellular level biology is where we first see signs of life
Cellular biologists look at biology one cell at a time
Examples:
A cellular biologist might look at how cancer attacks living cells

8. Cellular Biology

9. Multicellular level
Multicellular biology is the biology of complex organisms
A complex organism is anything that is made up of multiple cells doing many different jobs
Examples:
Medical doctors are one type of multicellular biologists because they look at how the body and its parts work together.

10. Multicellular Biology

11. Population Level
Some biologists look at populations of living organisms and how they interact with the environment
Example:
A population biologist might look at how birds migrate during the winter.

13. Global Level
Global biology is the study of everything on the planet and how it interacts with all the organisms living on Earth
Example:
A global biologist might want to look at how human beings could help the planet by finding out what can be recycled
