I Can Statements	Academic Vocabulary
I can describe the slope of the graphical representation of resistance vs. the ratio of length to cross-sectional area in terms of the resistivity of the material.	Resistance Slope Ratio Cross-Sectional Area Resistivity

Cross Cutting Concepts
Scale, Proportion, and Quantity Algebraic thinking is used to examine scientific data and predict the effect of a change in one variable on another (e.g., linear growth vs. exponential growth). Cause & Effect Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects. Systems and System Models *Models (e.g., physical, mathematical, computer models) can be used to simulate systems and interactions - including energy, matter, and information flows - within and between systems at different scales.

Develop graphical, mathematical, and pictorial representations that describe the relationship between length, cross-sectional area, and resistivity of an ohmic device and apply those representations to qualitatively and quantitatively describe how changing the composition, size, or shape of the device affect the resistance. (PI.8.1)	Develop graphical and mathematical representations that describe the relationship between the amount of current passing through an ohmic device and the amount of voltage (i.e. EMF) applied across the device according to Ohm’s Law and apply those representations to qualitatively and quantitatively describe how changing the current affects the voltage and vice versa.
