Scientific Measurements

Student will be able to1. Understand why scientist use a standard measure2. Describe the standard units of measure3. Describe common measure used in science4. Analyze graphing in science

• Common Practice

44

• Measurement Systems

– English System (red)– Metric System

Page 4: Measurement  Graphing

•Metric System Prefixes

– kilo (k) means 1,000 x– centi (c) means 0.01 x– milli (m) means 0.001 x– micro (µ) means 0.000001 x

45

Page 5: Measurement  Graphing

• Length (how long)

- Measured in Meter (m)+ Kilometer (km)+ Centimeter (cm)+ Millimeter (mm)+ Micrometer (µm)

46

Page 6: Measurement  Graphing

• Mass (how much stuff)

– Gram (g)+ Kilogram (kg)+ Milligram (mg)

48

Page 7: Measurement  Graphing

• Volume (how much space)

50

– Liter (l)+ Milliliter (ml)

Page 8: Measurement  Graphing

• Time

– Second

53

Page 9: Measurement  Graphing

• Temperature (movement)

– Celsius– Kelvin

54

Page 10: Measurement  Graphing

• Estimation

61

Page 11: Measurement  Graphing

• Accuracy & Precision

– Accuracy = How close is it to real value– Precision = How close is each measurement

to each other

62

Page 12: Measurement  Graphing

• Mean, Median, Mode

66

- Mean = Average- Median = Middle- Mode = Most often

- Graphs vs. Text

68+ Which is better?

At age 1, Sarah was 75 cm tall. By the time she turned 2, Sarah had grown 10 cm. By age 3, she had grown another 10 cm. At age 4, Sarah was 100 cm tall.

- Line Graphs

+ Example Experiment – Boiling Water

70

Page 16: Measurement  Graphing

- Line Graph

+ Draw Axis√ X “What you changed”

√ Y “What was measured”

+ Create Scale+ Plot Data+ Draw best fit line

71

Page 17: Measurement  Graphing

- Best Fit Line

+ Follow general trend+ Include as many points as possible+ Have same # of points above and

below

72

Page 18: Measurement  Graphing

- Identify Trends
