On your own paper, record 5 observations about this classroom. 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.

Label each qualitative or quantitative. But I can’t see (hear,smell,touch or taste) it! What do I do? There are some things that cannot be observed. cells Details of Planets and Stars Can you think of some ways scientists have solved this problem? 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. An inference is a statement based on your interpretation of the facts. Based on your previous observations, what do you think happened here? And here? Observation vs. Inference Observation Inference There is a car on the side of the road. The car is on the side of the road because it ran out of gas. The plant is drooping and the soil is dry. The teacher forgot to water the plant. The room smells and all the students are covering their faces. Someone ate tacos for lunch. Look at these two sets of animal tracks.

Why isn’t she using a fork? Where are they? Do they know each other? What happened here? What do you think he is going to say? What can you infer? How does she feel? What happened?
