• By Bridget Jackson, TJ Scott, Roxana Beladi,
  and Emma Kersey

Scientific Method

• Scientific Method is series of steps that is used
  to conduct an experiment.
• The steps are
• Purpose
• Research
• Hypothesis
• Experiment
• Analysis
• conclusion

3
Scientific Method

• Purpose
• Why is the lab is being conducted?
• What is trying to be discovered?
• What is the intent of the lab?
• The purpose gets the lab startedwith the problem

• Research
• Provides background information based on the
  purpose.
• Hypothesis is based off of this research.
• Extensive research is vital for better
  understanding of the lab.

4
Scientific Method

• Hypothesis
• Educated guess on what the outcome of the
  experiment will be
• Based on knowledge that you know and on what you
  find from your research.

• Experiment
• A series of actions that will prove the
  hypothesis correct or incorrect, and it must be
  controlled.
• The experiment contains an independent (the
  variable that is manipulated) and dependent
  variable (relies on independent variable).

5
Scientific Method

• Analysis
• This is to state the outcome of the experiment
  briefly.
• A graph or chart, according to the data, has to
  be shown to prove the outcome of the experiment.
• Also, any calculations, or qualitative data is
  shown in this area of the experiment.

• Conclusion
• This part of the experiment is to explain what
  happened, why, and what could be a possible
  future experiment.
• This also explains the independent and
  independent variables, as well as analyzing the
  data.

Characteristic of Life

• All living things
• Are made up of cells
• Have the ability to adapt
• Can reproduce
• Are based on a universal genetic code
• Are able to maintain a stable internal
  environment
• Grow and develop
• Evolve
• Obtain and use material and energy

10
Branches of Biology
11

• Individual- individual living thing
• Population- group of organisms of one type that
  live in the same area.
• Community- populations that live together in a
  defined area.
• Ecosystem- community and its surroundings.
• Biome- group of ecosystems that have the same
  climate and similar dominant communities.
• Biosphere- the part of Earth that contains all
  biomes.

Graphing

• We will cover terms including
• Independent variable
• Dependent variable
• Qualitative data
• Quantitative data
• Examples of appropriate graphing

16
Graphing

• Independent Variable
• Definition a factor in an experiment that a
  scientist purposefully changes also known as a
  manipulated variable.
• The independent variable is graphed on the
  y-axis.

• Dependent Variable
• Definition A factor in an experiment that a
  scientist wants to observe, which may change in
  response to the independent variable also known
  as the responding variable
• The dependent variable is graphed on the x-axis.

17
Graphing

• Qualitative Data
• Definition Data that is descriptive and involves
  characteristics that can not usually be described
  with numbers.
• Examples of qualitative data include color,
  shape, and mental or physical states.

• Quantitative Data
• Definition Data that is described by numbers,
  obtained by counting or measuring.
• Examples of quantitative data include
  percentages, ratios, measurements, and averages.

18
Graphing

• Types of graphs
• typically used in
• science
• Bar graph
• Line graph
• Pie Graph
• Scatter plot graph

This graph above is a line graph.
This graph above is an example of a bar graph
