Notes Thinking Like a Scientist

• Copy all underlined parts.
• Read pgs. 6-12.
• Objective Know how to use inference, prediction,
  and classification.

2
What is Science?

• Science is learning about the natural world
  through observation and experimentation.

3
Science Skills

• Scientists use skills such as observing,
  inferring, predicting, and classifying to learn

  observations.
• Inferences arent guesses, they are based on
  reason.

Making Models

• Making models involves creating representations
  of complex objects or processes.

16
Making Models

• Models help people study and understand things
  that are complex or that cant be observed
  directly.
