  1. Observations Biology 1

  2. Types of observations/research: • Qualitative: when the object is described in terms of quality. (It was green. It smelled like candy.) • Quantitative: when the object is described or measured in concrete numerical terms. (there are 30 students in my class. I ate 1 pound of potatoes.)

  3. Determine which are qualitative and which are quantitative: • The cup had a mass of 454 grams.

  4. Determine which are qualitative and which are quantitative: • The cup had a mass of 454 grams. Quantitative

  5. Determine which are qualitative and which are quantitative: • The temperature outside is 25° C.

  6. Determine which are qualitative and which are quantitative: • The temperature outside is 25° C. Quantitative

  7. Determine which are qualitative and which are quantitative: • It is warm outside.

  8. Determine which are qualitative and which are quantitative: • It is warm outside. Qualitative

  9. Determine which are qualitative and which are quantitative: • The tree is 30 feet tall.

  10. Determine which are qualitative and which are quantitative: • The tree is 30 feet tall. Quantitative

  11. Determine which are qualitative and which are quantitative: • The building is taller than the tree.

  12. Determine which are qualitative and which are quantitative: • The building is taller than the tree. Qualitative

  13. When does an observation become an inference? • Observation: Using one or more of your senses to gather information and record facts. • Example: There is one projector in the room.

  14. When does on observation become an inference? • Inference: logical interpretation based upon prior knowledge and experience. • Example: Since students are wearing coats, it must be cold outside.

  15. In a Lab Setting • Record your data as observations and facts, NOT inferences. • Inferences can be used in your analysis and conclusion portion of your lab report.

  16. Now, lets practice! • Observation/inference practice
