1. Rise over Run/Mass over Volume/ g/cm 3 = Density Mass (g) Volume (cm 3 ) Rise Run Best Fit Straight Line The Density of my Dogs Food Title Describe each axis with units

2. If you increase the mass of an object; the volume increases. Mass (g) Volume (cm 3 ) Rise Run The Density of my Dogs Food

3. More Mass = More Volume More Volume = More Mass Mass (g) Volume (cm 3 ) Rise Run The Density of my Dogs Food

4. Slope:Draw 2 Points on the Line Mass (g) Volume (cm 3 ) Rise Run Make it easy; pick points on grid lines! The Density of my Dogs Food

5. Slope: Draw 2 Lines to the Y Axis: Draw 2 Lines to the X Axis Mass (g) Volume (cm 3 ) 4 g 3 cm 3 The Density of my Dogs Food

6. Slope = Rise over Run: Y Over X Mass (g) Volume(cm 3 ) 4 g 3 cm 3 Rise = 4 grams Run = 3 cm 3 Density = 1.33 g/cm 3 Mass = 4 grams Volume = 3 cm 3 The Density of my Dogs Food
