Algebra
Given two points on a line of best fit (2,5) and (5, 26), find the slope of the line.
m = 7
Use this graph if you have a qualitative IV and quantitative DV, and you are measuring parts of a whole or percentages.

What were the IV and DV of the DBH lab?
DV: Tree Diameter (m)
It's the "C" in CRAAP. Define what it means as well.
Currency: describes how current or up to date the information is.
This variable describes the amount of thermal energy something holds. (For full points, give the standard unit as well)
Temperature (K)
Given two points on a line of best fit (2,5) and (5, 26), find the y-intercept of the line.
b = -9
Use this graph if you have a qualitative IV and quantitative DV, and you have categorical data that isn't parts of a whole or percentages.
Bar Graph
What were the IV and DV of the Tying Knots (Rope length) lab?
IV: Number of Knots
DV: Length of Rope (m)
It's the "R" in CRAAP. Define what it means as well.
Relevancy: is the source related to your topic and is it appropriate for your audience (can you read it?)
This variable describes the length of space between two points. (For full points, give the standard unit as well)
Distance (m)
Write a properly formatted science equation for the following experiment and line of best fit:
IV: rainfall (cm)
DV: Grass Height (cm)
y = 1.5x+2
Grass Height (cm) = 1.5 (Rainfall (cm)) + 2 cm
Use this graph if you have both a quantitative IV and DV, and you want to see the relationship between the IV and the DV.
Scatter Plot
What were the IV and DV of the E. Coli Lab?
IV: Time (min)
DV: E. Coli Population (Colonies)
It's the "Au" in CRAAP. Define what it means as well.
Authority: Who wrote it? Are they qualified to talk about the topic?
This variable measures the duration between two events. (For full points, give the standard unit as well)
Time (s)
Write a properly formatted science equation for the following experiment and line of best fit:
IV: Water Temperature (°C)
DV: Amount of Sugar Dissolved (g)
y = 12x+5
Amount of Sugar Dissolved (g) = 12 g/°C (Water Temperature (°C)) + 5 g
Use this graph if you have both a quantitative IV and DV, and your IV is continuous change over time.
Line Graph
What were the IV and DV of the Heating Water Lab?
IV: Time (s)
DV: Water Temperature (°C)
It's the "Ac" in CRAAP. Define what it means as well.
Accuracy: Is the information correct?
This variable describes the amount of matter in an object. (For full points, give the standard unit as well)
Mass (kg)
Write a properly formatted science equation for the following experiment and line of best fit:
IV: Time (s)
DV: Velocity (m/s)
y = -9.81x+50
Velocity (m/s) = -9.81 m/s2 (Time (s)) + 50 m/s
