Unit One Foundations of Biology
Chapter 1
The Science of Life
Chapter 1: you should be able to…Describe the importance of Biology in
society.List and understand the characteristics of
living things.Distinguish between homeostasis and
metabolism.Use the Scientific Method in order to
effectively communicate the results of a controlled experiment.
Identify the parts and functions of a compound light microscope Compare/Contrast 2 types of electron
microscopes.

Would fertilizer affect how tall a plant would
grow?
Write a hypothesis:If___________________

IDENTIFY THE DEPENDENENT AND INDEPENDENT VARIABLES:
Plant height depends on whether or not the plant receives fertilizer…SO…
IV=____________________
DV=___________________
Would fertilizer affect how tall a plant would grow?
The Study of BiologyCollecting and Analyzing Data________________________Graphs and Charts
Which is Qualitative?Which is Quantitative?
1. That solution is bright pink, the other is milky white.
2. There were 534 brown mice and 236 white.
3. I feel sad.4. This sample smells a lot like cheese.5. There are 3 red, 5 blue and 6 pink.
