Scientific Inquiry

This introductory chapter on scientific inquiry explores how scientists address questions concerning the natural world. It outlines the scientific method, which consists of eight steps to systematically solve problems. The first step involves posing a testable question, followed by forming a hypothesis that proposes a potential explanation. Observations and inferences are gathered through our senses to inform these processes. An engaging brown bag experiment encourages practical application, allowing learners to investigate the nature of objects without direct observation.

Presentation Transcript

  1. Scientific Inquiry Prelude to Chapter 1

  2. Scientific Inquiry Is the different ways scientists use to solve questions about the natural world. Scientific Method: • One way scientists solve questions about the natural world. • There are 8 Steps

  3. First Step of the Scientific Method Posing a Question: • Ask about something unknown. • Examples: • Why is the sky blue? • Will it rain on Friday? • What will my friends think of my new shirt? • Each question is unknown and can be tested. • Take a few minutes to write down a Question in your Notebook.

  4. Second Step of the Scientific Method Forming a Hypothesis: • A possible explanation for observations that relate to a scientific explanation. • Tested by observations or experiments. • “If, then” statements. • Example: “If the Sun were to burn out, then life on Earth would not exist.” • In your notebook, practice writing a hypothesis.

  5. When forming a Hypothesis… • Observation: • Using the 5 senses to gather information. • Inference: • An interpretation based on your observation and prior judgment. • Example: You know it’s a coin, but are not sure whether it’s a Nickel or a Penny.

  6. Brown Bag Experiment • Instructions: • Do not Open the Brown Bag. • Use your senses of sound and touch to determine the 5 objects in each bag. • Record your findings on your worksheet.

  7. After Lab Recap • Observations that you made: • What did you feel? • What did you see? • Were you able to use any other senses? • Inferences that you made: • Coin? • Noodle? • Paperclip? • Q-Tip?
