4. Think about it…
News stories you have heard – these stories involve biology – the science the employs scientific methodology to study living things… cloning, drug abuse and brain damage and the bird flu

5. Characteristics of Living Things
are made up of cells – basic units of life
have a universal genetic code - DNA
obtain and use materials and energy - metabolism
grow and develop
Reproduce – sexual/ asexual

Maintain a stable internal environment - homeostasis
Change over time – living things evolve
Metabolsim – combination of chemical reactions through which an organism builds up or breaks down materials.

6. Is It Alive?
The fish are clearly alive, but what about the stuff around them?

7. Performing Biological Investigations Scientific Measurement
Based on multiples of 10.
Most scientists use the metric system when collecting data and performing experiments.
