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

2. Student Biography What was your last science/math class?
What was your grade?
What is your strongest and weakest subjects?
Do you have access to a home computer?
What are your hobbies/interests?
Do you have a job after school?
What type of career are you interested in pursuing?

3. What is Chemistry?

4. Study of matter and the changes matter undergoes.

5. Describe what this picture says to you about chemistry.

6. Chemistry

7. Bell Ringer: Scientific Method

10. 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.

11. Airplane Lab Objectives: Scientific Method
Independent vs. Dependent Variable
Quantitative vs. Qualitative Data
Scientific Notation
Metric Conversions

12. 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.

13. 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

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

15. Accuracy and Precision
To learn why it is necessary in science to use these in measurments.

17. good accuracy but poor precision
good precision & good accuracy
poor accuracy but good precision
poor precision & poor accuracy

19. Quantitative Measurements
Scientific Notation:
To abbreviate very large or very small measurements.
0.0025cm = 2.5 x10-3 cm
250 cm = 2.50 x102 cm

20. Metric Conversions

21. Metric Conversions
k  h  dk  base  d  c  m Convert m to cm = cm Convert kg to g = 4.8 g

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

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

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

25. 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

26. Measurement Conversions
Density = mass/volume
K = 0C
0C = 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.

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

28. 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

29. Density Lab
Experimental Group
Experimental Density Values
(g/mL)

30. Density Lab

31. Scientific Skills Review

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

33. Bell Ringer: Calculations with Measurements
