  2. Why is classroom and laboratory safety important?

  3. Science Safety Rules • Follow all written and oral instructions. • Read and review ALL instructions. • Do only lab work that is approved by the teacher. • Only materials and chemicals supplied by the teacher may be used.

  4. Science A way of learning about the natural world Topic: What is Science?

  5. Scientific Inquiry A diverse way in which scientists explore problems and answer questions about the natural world Topic: What is Science?

  6. Observation Involves: Sight Hearing Smell Taste Touch Topic: What is Science?

  7. Inference An interpretation based on observation and prior knowledge Topic: What is Science?

  8. ~Checkpoint~ What is the difference between an observation and an inference?

  9. Scientific Methods Posing a question Developing a hypothesis Testing *Controlled Experiment Gather data Draw conclusions Topic: What is Science?

  10. Scientific Method Video

  11. Hypothesis An educated guess Can be tested Topic: What is Science?

  12. ~ Checkpoint ~ What is a hypothesis? A hypothesis is an educated guess.

  13. Variable Factors that can change in an experiment Topic: What is Science?

  14. Independent variable Variable that the scientist can change Topic: What is Science?

  15. Dependent Variable Changes because of independent variable Topic: What is Science?

  16. Controlled Experiment Test of a hypothesis in which only 1 variable can affect the outcome of the experiment Topic: What is Science?

  17. Data Evidence gained through observation Topic: What is Science?

  18. Simulation Model that imitates something in the real world Topic: What is Science?
