1. 9/12/14 Aim: What is the difference between an observation and an inference? Do Now: Pretend you are Christopher Columbus trying to get funding for your expedition. How can you convince the King and Queen that the earth is round and that you will not fall off when you travel around the earth? HW. R&H pp. 2-4, A&E #1-9, Track storms

2. Notes Earth Science – A study of Geology, Oceanography, Meteorology, and Astronomy.

3. Geology – the study of history, structure, processes and composition of earth’s solid surface down to earth’s center.

4. Oceanography – the study of all aspects of earth’s oceans.

5. Meteorology – the study of earth’s atmosphere, including weather and climate

6. Astronomy – the study of the universe, that is all matter, time, energy, and space.

7. Observation – a means of collecting data using one of your 5 senses (sight, hearing, touch, smell, or taste) – or- the use of an instrument to extend one of your senses and to get a more accurate observation by taking a measurement.

8. Inference- is a conclusion drawn based on your observations. It could also be a prediction or an educated guess based on what you observed. * Many times your inference may be wrong.

9. Classification – the grouping together of your observations based on common observable properties. This helps to organize your findings and aids in seeing patterns so that you may accurately make predictions.

10. 9-15-14 Aim: How do we calculate % error? Do Now: Let’s say you scored a 75 on an exam. What was your % correct and what was your % error? HW: Finish lab, Track storms

11. Measurement- a more accurate way to observe by using an instrument to extend your senses. Realize that all measurement will contain some error and that error can be quantified by using the following formula Percent Deviation (error) the % off a measurement is % Deviation = difference from accepted value Accepted value X 100

12. 9-17-14 Aim: What are the graphing relationships? Do Now: 1. R&H pp.7-9 2. I measure the elevation of WHB to be 25 feet above sea level, when it is actually 19 feet above sea level. Calculate my % error in measuring. HW- Finish lab, A&E p.10 #19-28

13. Change- when the properties of an object or system are altered. Rate of change – how fast change is occurring. Rate of change = change in field value change in time Cyclic change occurs in a repeating pattern that can be predicted. Dynamic Equilibrium – when there is a balance among changes (rainfall into a lake = evaporation from the lake, keeping the level of water the same or balanced. *Most changes on the earth are cyclic and predictable.
