What is Science?

Science is a process we use to answer questions about what we OBSERVE.

4
OBSERVATIONS When you observe you become aware of something by using your senses: smell, sight, sound, touch and taste. An observation is a statement describing a fact.

6
Qualitative vs. Quantitative Observations can be qualitative or quantitative. Qualitative observations cannot be measured. Examples: red, hot, beeping noise Quantitative observations can be measured. Examples: 72 degrees, 18 centimeters, 45 mph

Quantitative or Qualitative? The room is cold.

17
Record 2 qualitative and 2 quantitative observations on your paper.

18
Record 4 observations. Label each qualitative or quantitative.

20
But I cant see (hear,smell,touch or taste) it! What do I do? There are some things that cannot be observed.

21
cells

22
Details of Planets and Stars

23
Can you think of some ways scientists have solved this problem?

24
Scientists often use inferences. Inferences cannot be directly observed. They require thought!! When you infer you make educated guesses and judgements based on your observations.

25
An inference is a statement based on your interpretation of the facts.

26
Based on your previous observations, what do you think happened here?

27
And here?

28
Observation vs. Inference ObservationInference There is a car on the side of the road. The plant is drooping and the soil is dry. The room smells and all the students are covering their faces. The car is on the side of the road because it ran out of gas. The teacher forgot to water the plant. Someone ate tacos for lunch.
