### Living Things

Types of Graphs: BAR GRAPH

• Use for “chunking” or ________ data

• Show trends and ____________

• Does NOT allow ____________comparisons

Grouping

Compare Sizes

Cause and effect

Use for displaying __________

Does NOT allow ________________ comparisons

A. Graphing Techniques

Types of Graphs: CIRCLE OR PIE GRAPH

Percentages

cause and effect

Types of Graphs: LINE GRAPH (scatter plot)

• Used most often in ________

• Independent/

• Dependent Variable Comparison _______________

Science

Cause and effect

TWO VARIABLES

WITH DIFFERENT SCALES

Just because you can graph two things does not mean one _________ the other

• X is across, Y is up high

• Independent = manipulated (cause)

• Dependent = responding (effect)

• Label x and y axis, title the graph

• When time is a variable, it always appears on the X-Axis (Time is the ultimate independent variable; time waits for no one!)

What distinguishes a living thing from a non-living thing?

The study of living things is called _____________

Biology

There are 8 characteristics of living things.

Living things:

1. are made of basic units called cells.

2. are based on a common genetic code.

Generally: DNA

3. obtain and use materials and energy.

4. grow and develop.

5. reproduce.

6. respond to their environment.

7. maintain a stable internal environment

(homeostasis)

8. taken as a group, change over time (evolve)
