To understand scientific thinking to illustrate scientific thinking

Objectives

  • To understand scientific thinking

  • To illustrate scientific thinking

  • To describe the method scientists use to study nature


A solving everyday problems

A. Solving Everyday Problems

  • Scientific thinking helps us solve all types of problems we confront in our lives.

  • Scientific thinking involves

    • observations

    • defining a problem

    • construction of explanations

    • evaluation of possible explanations or solutions to the problem


B using scientific thinking to solve a problem

B. Using Scientific Thinking to Solve a Problem

David and Susan have symptoms of lead poisoning


B using scientific thinking to solve a problem2

B. Using Scientific Thinking to Solve a Problem

No other customers have symptoms – lead is not from food


C the scientific method

C. The Scientific Method

  • The scientific method is a procedure for processing the information that flows from the world around us in which we:

    • Make observations

    • Formulate hypotheses

    • Perform experiments to

      test our hypotheses

C. The Scientific Method

Observations Are Not Hypotheses

  • An observation can be witnessed and recorded.

  • A hypothesis is an interpretation – a possible explanation of why something happens.

Write down three observations and three related hypotheses

Types of Observations

  • An observation can be qualitative or quantitative

  • Quantitative observations include both a number and a unit

Write down three quantitative and three qualitative observations

C. The Scientific Method

Theories Are Not Laws

  • A natural law is a summary of behavior.

  • A theory is our attempt to explain why it happens.

  • Theory or Law?

    • Metals are more dense than gases

    • Gravitational forces make a pen drop to the bench

    • Hydrogen atoms are usually found in pairs

    • Gas burns because the methane combines with oxygen and gives off heat and light
