Science is a way of knowing.

1. Hypothesis A possible explanation or answer to the question 2. Independent (manipulated) Variable 3.Dependent (responding) Variable 4. Controlled Variables.

Observing We observe when we use one or more of our senses to find out about objects, events, or living things An observation is a FACT learned directly.

Observations Observations- Using our five senses to gather information about the world around us. There are two types of observations. Qualitative & Quantitative.

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

Observations An observation is any information that we gather using our five senses. EXAMPLE:

Using one or more of your senses to gather information about an object or your surroundings. What are the senses we use in science class? Sight Touch.

Presentation transcript:

Understanding Observations (with Observation & Inference handout)

Definition of observation Gathering data by use of your senses or tools that extend your senses

Qualitative observations Characteristics or properties

Quantitative observations Counting or measuring

How can you remember the difference? (Qual)itative: related to quality = characteristic (Quant)itative: related to quantity = number

Definition of inference Conclusion drawn from using both observation and background knowledge

Difference between observation and inference Observation is just what you perceive with your senses. Inference adds in what you know from past learning and experience to explain what you observe.

Examples It is a candle There appear to be 3 red and 4 yellow spots He was absent because he was sick She is in college It is rotten It feels smooth He sounds like a mouse It looks like it has 8 legs It tastes like spoiled milk He is 6 ft. 5 in.
