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.

homework, then_______________________. If I forget my goggles on lab

day___________________________________.

Answer the following as an IF/THEN statement:

Would fertilizer affect how tall a plant would

grow?

Write a hypothesis:If___________________

_____________________, then__________________________________________.

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.
