SCIENTIFIC METHOD #1 : IDENTIFY THE PROBLEM OR ASK A QUESTION BASED ON AN OBSERVATION.

I. Making Observations- Observations can be made several different ways. Observations can be put into two different categories; qualitative and quantitative.

1. Prediction: to tell something before it happens 2. Hypothesis: a possible answer to a question based on gathered information.

Observation and Inference. Observations ► A noting and recording of…. FACTS!!! ► Uses all 5 senses. ► Example: There is one TV in the room.

INFORMATION GATHERED BASED ON OUR FIVE SENSES THERE ARE TWO TYPES OF OBSERVATIONS… Think about what we learned about observations…

Scientific Method Vocabulary Review. The steps scientists take to create, test, and prove a hypothesis.

Observations and Inferences Using your senses and making sense of your observations.

 When describing something, use only facts that you can see, feel, smell, taste and hear  This is not an opinion!!!!!

Observations Inferences

Inference vs. Observation A. The act of reasoning from factual knowledge or evidence. B. Very similar to an assumption. 1. Ex: The sun will come up tomorrow 2. Ex: If you put your hand in boiling water it will burn.

Observation A. The act of noting and recording something B. For something to be observed, some type of instrument must be used 1. Ears, Eyes, Thermometer 2. Observations are recorded as data Types of data A. Qualitative 1. 'Soft' data that approximates but does not measure the attributes, characteristics, etc., of a thing or phenomenon.

2. Qualitative data describes whereas quantitative data defines. 3. Ex: Color, general shape, how you feel B. Quantitative data 1. Measurable data that can be statistically manipulated 2. Measures quantities or “how much” 3. Ex: 6 inches, 560 nm, IQ=120 a. If it exists there is probably an instrument to measure it.
