  2. Science: Knowledge about the natural world derived from observations and experiments. The purpose of science is to make discoveries about the world around us.

  3. Observation: Using your 5 senses: seeing, hearing, tasting, smelling, touching. • Inference: These are attempts to explain or make sense of observations. An inference has a cause and effect in it.

  4. Controlled Experiment: • An experiment in which variables are controlled to make results reliable and the experiment fair. You attempt to control every variable except one.

  5. Qualitative Observations: Do not involve numbers or measurement. (bigger/smaller, color, yes/no) • Quantitative Observation: Do involve numbers or measurement. (3 mL, 4 cm, 6 pieces)

  6. Prediction: Telling about something in advance. • Hypothesis: An assumption to be tested. A statement that needs to be proven. • Investigative Questions: Scientific questions that ask: why, what if, when, how, and can it happen again.

  7. Talk to your partner… • What is the difference between a prediction and a hypothesis? • What is the difference between an observation and an inference? After discussing each question, write your answers on the back of your notes.
