Science Starter!

Perform the following conversions and dimensional analysis problems. Reflect your answer in scientific notation.

30 in  mm

12 cm  mi

50 mi/hr  m/s

25 ft/s  cm/hr

Parts of a Graph

“Best Fit” Line

Variable that is measured during an experiment (y - axis)

Variable that is controlled in an experiment (x - axis)

distinguishing variables
Distinguishing Variables

Example:

I worked for 5 hours and made $50.

Independent: What did YOU directly control (do)?

5 hours

Dependent: What happened because of your action (measure)?

made $50

EXCEPTION: TIME is always considered an independent variable, even though it may be the quantity measured.

types of relationships
Types of Relationships

LINEAR

- Straight line

- Equation: y = mx + b

- Direct Relationship

Slope [Steepness of line] = (Y2 – Y1) or RISE (X2 – X1) RUN

graphing data
Graphing Data

Data Chart

- Determine the independent and dependent variables

Plot Data

- Place a dot at the intersection of the two variables

calculating slope
Calculating Slope
  • Choose any two points on the line of best fit:
  • (not data points)EX: ( y = 15, x = 30) and ( y = 0, x = 0)
  • Calculate slope by dividing the difference in the “y” values by the difference in the “x” values:
  • EX: Slope = (15 – 0)
  • (30 – 0)
  • Slope = 0.5
enclosed area
Enclosed Area
  • Shade in the region in question:
  • EX: Find the area enclosed by the line of best fit and the horizontal axis between x = 0 and x = 30.
  • Use geometry and the values on the axis (NOT number of blocks) to find the area of the shape made.
  • EX: A = ½ bh
  • = ½ (30)(15) = 225
slide13

Area = ½ bh

= ( ½ )(6)(14.5)

= 43.5
