  1. 09/12/2018 Mrs. Nainani 7th grade AIM: Observation & Inference • Do now : Make 5 observation. What is going on in this picture? What are they doing?

  2. Observations vs. Inferences “You can observe a lot just by watching.” -Yogi Berra

  3. Observations • An observation is the gathering of information by using our five senses: • Sight • Smell • Hearing • Taste • Touch • There are two types of observations • Qualitative • Quantitative

  4. Qualitative Observations • Qualitative observations describe what we observe. • “Qualitative” = quality (descriptive) • These observations use adjectives to describe something. • Example:The rose is blue. • Example:Mrs. Nainani has brown eyes.

  5. Quantitative Observations • Quantitative observations measure what we observe. • “Quantitative” = quantity (numerical) • These observations use numbers to measure something in a quantitative way. • Example:The flower has 7 petals. • Example:Mrs. Nainani’s height is 5’2.

  6. Is this a qualitative observation or quantitative observation? The road is long. The road is 5 km long. SUPPORT YOUR ANSWER!

  7. Which is better? • Both types of observations are valuable in science. In experiment, quantitative observation can be more accurate.

  8. Activity • Guess who? • Make 5 observations of a person in this room. • Include at least one Quantitative observation and one Qualitative observation. • Present your observation to the class. • Others will guess who that person is!

  9. AIM: Observation & Inference • Do now : Write N for quaNtitative observation and write Lfor quaLitative observation. You may refer to your note from last week. • 1. There are 2 gallons of milk. • 2. Sue has red hair. • 3. The cat has a short tail. • 4. It is raining out side. • 5. I have 500mL of water. • 6. The sun rose at 6:10 a.m. in this morning.

  10. Inferences • Inferences are an explanation for an observation you have made. • They are based on your past experiences and prior knowledge. • Inferences are often changed when new observations are made.

  11. Inferences • Again, observations are information we gather directly through our five senses….inferences help explain those observations!

  12. Distinguishing Observation and Inference • Example: Mrs. Nainani

  13. Here are some examples! • All of these inferences could possibly explain why the grass is wet. They are all based on prior experiences. We have all seen rain, sprinklers, morning dew, and dogs going to the bathroom.

  14. Here are some examples! • Again, these are all logical explanations for why the fire alarm is going off.

  15. Last one! Why might a student be sitting there?

  16. Observations, or Inference? 1. The cat is wearing a lime on it’s head. ______ 2. The cat likes eating limes. ________ • Mrs. Nainani put the lime on the cat’s head. _____ • The lime is green. _____ • The cat likes wearing the lime helmet. ______ • The cat is white. _____

  17. AIM: Observation & Inference • Do now : What is qualitative observation? What is quantitative observation? Make 2 quaNtitativeobservation and make 2 quaLitativeobservation.
