**Picture of a Lab – Different Graph Types**

Station #1 investigates the relationship between force and displacement of a stretched spring. Students will discover a direct linear relationship, with an equation of the form y = mx + b. Station #2 demonstrates Boyle's Law, or the relationship between the pressure on a gas and its volume. The graph is a hyperbola, y = 1/x. Station #3 relates light intensity to distance from the source. The graph shows an inverse-square relationship, with an equation y = 1/x^{2}. Station #4 uses staggered, stacked blocks to result in a simple parabolic graph, where y = x^{2}. Click here for applicable science standards
