1. Classroom Rules 1.Students must be in the classroom when the bell rings. 2.Bring all materials to class with you. (paper, pencil/pen, assignments, and resources) 3.Students must raise hand before getting up out of seat or answering a question. 4.Assignments must be placed in tray when requested. 5.Teacher will dismiss class not the bell.

2. Bell Ringer: Scientific Method 1.What are the steps to the scientific method? 2.Why do scientists use the scientific method? 3.How have you used the scientific method outside of science?

5. How do you process information best ? nwlink.com Hypothesis:

6. Scientific Method: Multiple Intelligences Test your hypothesis with an experiment. Complete Multiple Intelligences Test

7. Student’s Multiple Intelligences Results How would you organize your results so you can interpret easily?

8. Student’s Multiple Intelligences Results Ling./ word Logic/ Math Spatial/ Visual Music B-K Hands- on Inter- person al group Intra- persona l individu al Nature

9. Student’s Multiple Intelligences Results Illustrate your results from table in a graph. ( bar graph). *Make sure that table and graph have a title. *Create a legend for graph. If bar graph label x and y axis.

10. Student’s Multiple Intelligences Conclusion: 1.State your results from the experiment. 2. Compare experimental results with your hypothesis.

11. Scientific Skills Objectives I can identify the importance of the scientific method and apply it to real world applications. I can understand the difference between precision and accuracy. I can compare the difference between qualitative and quantitative results. I can convert quantitative results using metric and english conversions. I can express large and short numbers using scientific notation.

12. Airplane Lab Objectives: a.Scientific Method b.Independent vs. Dependent Variable c.Quantitative vs. Qualitative Data d.Scientific Notation e.Metric Conversions

13. Laboratory Objectives Students will be able to recognize and apply the correct lab equipment for each lab. Students will be able to measure and analyze experimental data correctly.

14. Experimental Design Independent variable - variable “I” control in the experiment. -Always plot on x-axis Dependent Variable -variable depends on the independent variable -Always plot on y-axis

15. Experimental Data Qualitative Data data you observe thru your senses Quantitative Data data that is measurable

16. Accuracy vs. Precision Accurate Results: When one compares the avg. expt. data with the actual value. Precise Results: When one compares expt. trials with one another.

17. Quantitative Measurements Scientific Notation: To abbreviate very large or very small measurements. 0.0025cm = 2.5 x10 -3 cm 250 cm = 2.50 x10 2 cm

18. Metric Conversions

19. k  h  dk  base  d  c  m Convert 0.0748 m to cm = 0.00748 cm Convert 0.0048 kg to g = 4.8 g

20. Metric to English k  h  dk  base  d  c  m a. How many meters are in a 100 yard football field? b.How many centimeters are in 2 feet ? c. Convert 4 pounds (lbs.) to milligrams?

21. Metric to English k  h  dk  base  d  c  m d. Convert 15 kilometers to miles.

22. Class Results on Airplane Flight Group #Airplane Model Average Flight Distance (cm) 1 2 3 4 5 6 7

23. Lab Experiments Background Terminology -Independent vs. Dependent Variables -Qualitative vs. Quantitative Data -Accuracy vs. Precision -Measurement Conversions (scientific notation, metric, and metric to english) New Terminology: -Significant Figures

24. Measurement Conversions Density = mass/volume K = 0 C + 273 0 C = K – 273 1 m = 1.09 yd 2.54 cm = 1.0 in. 1.0 km = 0.62 mi. 1.0 mi. = 5,280 ft 454 g = 1.0 1b.

25. Factor Label Method k  h  dk  base  d  c  m

26. Significant Figures Significant Figures: The certain numbers in a measurement plus the first estimated number. Which of the following measurements is most precise and why? a.3 b.3.0 c.3.00 d.3.000

27. Measurement Lab How do scientists limit the degree of uncertainty in a measurement? Appropriate instrument Repeat expt. trials for precision and accuracy Observing significant figures Purpose: Establish a relationship between significant figures and accuracy

28. Calculating Measurements Multiplying and Dividing: The # of significant figures in the answer is the same as the measurement with the least number of significant figures. Addition and Subtraction: The # of significant figures in the answer is the same as the measurement with the least number of decimal places.

29. Bell Ringer: Calculations with Measurements 1.Calculate the following measurements with.the correct number of significant figures a. 8.3 m x 0.0020 m = b. 4.10 g + 3.4g + 8g =

30. Density Lab Experimental GroupExperimental Density Values (g/mL)

31. Density and Temperature D= mass/volume (Heart) Temperature commonly measured in 0 C K = 0 C + 273: K= Kelvin o C= degrees Celsius
