What is Science?
A way of describing, predicting, and explaining nature and its changes in the simplest way possible
Scientific Method
The process of scientific research What are the parts of the scientific
method?
Question, Hypothesis, Design, Materials, Procedure, Evidence/Data, Analysis/Conclusions, Evaluation
3 Variables:
Control
Manipulated (independent)
Responding (dependent)
BIOLOGICAL
DIVERSITY!
WHAT IS IT??
The number and variety of organisms
What will we learn this unit?
Diversity of life on Earth How living things pass on their traits
to future generations Investigate the impacts of human
activities on biological diversity Understand issues and decisions
associated with future activities.
Questions to wrap our heads around:
What does biological diversity look like?
How do organisms pass on their traits?
How can we prevent the loss of biological diversity on Earth?
Exploring Variation- pg. 8
All Domestic cats belong to one species,
Felis catus. However, these cats show many variation
Let’s take a look at some pictures of cats!
Two Types of Data
Discrete: A limited number of variations or categories; either/or. Example: Tall or short Bar Graph
Continuous: A range of variations or possibilities. Example: Height – 5’1”, 5’2”, 5’3”, 5’4”,
5’5”… Histogram
Three types of graphs!
Bar Graph: uses bars, shows a comparison between groups.
Three types of graphs!
Line Graph: joins points together to show progression or growth
Histograms
Continual data, summary graph
Showing a count of the data points falling in various ranges
