Graphing

100

What are the two axes on a graph 

x and y axes

200

Which variables go on the x and y axis 

X Axis - Manipulated/Independent

Y Axis - Responding/Dependent

300

What variable is the variable we measure

Responding/Dependent

400

What is a linear line on a graph

What is an exponential line on a graph

Linear: A graph where the value changes by the same amount each time. It forms a straight line. 

Exponential: A graph where the value changes by the same factor/percentage each time. It forms a curved line that gets steeper (for growth).

List everything you must do to have a perfect graph

1. Title (Responding variable (y) vs Manipulated Variable (x)

2. Label x and y axes + units

3. Number x and y axes 

4. Circle Data Points 

5. Draw Trendline (Line of Best Fit) 

6. Have a key if needed 

Density

100

What is the formula for density?

D=M/V

200

What is the formula for mass using volume and density

M=VxD

300

If an object has a mass of 150g, and a volume of 65cm^3, what is the density of this object

2.3g/cm^3

400

There is a perfect cube that has the volume of 216cm, what is the length of one side of the cube

6cm 

500

There is a perfect cube where the length is 4cm, the mass of this object is 264kg, what is the density of the object

4125g/cm^3

264kg --> 264000g

4x4x4=64cm^3
