An image rich, one of a kind Power Point that teaches students the meaning of a, "light year" using simple inter-active math activities. This conceptual and quantitative presentation starts off slow with the "snail year" (268.2 mi.; 431.6 km) and progresses through the "walk year", the "car year", the "jet year", the "sound year" (6,307,200 mi., 10,150,454 km) , the "bullet year", and finally . . . the "LIGHT YEAR" (not Buzz!). Includes astronomical applications of this enormous distance unit. S

This package includes three image rich, interactive Power Points, five companion worksheet activities/note pages. "Rates of Motion" includes a conceptual and quantitative exploration of speed and acceleration. Quantitative activities involve using distance and time to calculate average speed; using speed and time to calculate the unknown distance; using speed and distance to calculate unknown time; and two different acceleration formulas for calculating the rate of speed changes.

Pi Day is a presentation Power Point intended to teach students the concept behind the well known number (3.1416). Includes some levity.
