Picture of a Lab: Different Graph Types

Picture of a Lab – Different Graph TypesStation #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/x2. Station #4 uses staggered, stacked blocks to result in a simple parabolic graph, where y = x2. Click here for applicable science standards

In order to use the data logger in this experiment, the computer would need to be of PC version (Windows). The "Several identical weights or books" required for this lab are any objects that you may have or that can also be purchased from your local convenience or hardware store that are identical in weight. The "wood blocks" required for this lab can be cut from any lumber that you may have or purchased from your local building supply store. The blocks should all be identical in measurements.
