SCI.8.PC.1.b: Science

Students know that average speed is the total distance traveled divided by the total time elapsed and that the speed of an object along the path traveled can vary.

SCI.8.PC.1.c: Science

Students know how to solve problems involving distance, time, and average speed.

SCI.8.PC.1.f: Science

Students know how to interpret graphs of position versus time and graphs of speed versus time for motion in a single direction.

Reviewer Comments:

Intended for 8th grade life science students, this set of lab activities gives students an opportunity to investigate average speed, data collection, graphing, extrapolation and interpolation of data using meter sticks and marbles. Other activities have students manipulating variables such as ramp angle or mass of ball. Each activity is aligned with California State Science Standards (Motion) and includes a student handout. Although there are no answer keys included, it is fairly easy to follow the procedure of each experiment. Some excellent introductory and assessment materials are suggested, but educators may have to do a little work to access them. Overall, this resource would be engaging and informative at its intended grade level.
