Big Idea 1: The Practice of Science

A: Scientific inquiry is a multifaceted activity that includes:

  • Scientific questions

  • Diverse investigations

  • Collection of data

  • Analysis of data

  • Communication of results

    B: The processes of science frequently do not correspond to "the scientific method."

    C: Scientific argumentation is a necessary part of scientific inquiry

    D: Scientific knowledge is based on observation and inference; it is important to recognize that these are very different things.

Process & Nature of Science

Observation-

  • Using your 5 senses to gather information about your surroundings

    Inference-

  • A conclusion based on evidence

  • An “educated guess”


Effective science instruction
Effective Science Instruction

  • Includes all 3 aspects of science:

    • Knowledge of Science

    • Processes of Science

    • Nature of Science

  • Don’t Confuse Science Processes w/Nature of Science!

What s the point
What’s the Point?

  • Good way to practice making observations and inferences (process skills)

  • Reinforces concept that scientific knowledge is based on observations and inferences (nature of science)



The proof is in the cookie1
The “Proof” is in the Cookie

  • Make observations of cookie


The proof is in the cookie2
The “Proof” is in the Cookie

  • Make observations of cookie

  • Make inferences about what’s inside


The proof is in the cookie3
The “Proof” is in the Cookie

  • Make observations of cookie

  • Make inferences about what’s inside

  • Eat the cookie; then revise inferences


The proof is in the cookie4
The “Proof” is in the Cookie

  • Make observations of cookie

  • Make inferences about what’s inside

  • Eat the cookie; then revise inferences

  • Discuss observation & inference

    • Scientific knowledge is based on observation AND inference

    • Sometimes scientists can’t directly observe what they want to know.

    • Good inferences allow us to be very sure of things we can’t directly observe.



Field geology 201
“Field Geology” 201

Your geology class is on a field trip to a fossil bed in Alberta, Canada. While exploring the site, you discover a slab of rock covered with interesting impressions. Your instructor invites the class to make observations and inferences about the imprints…
