Students will calculate average speed of a marble going down a ruler. They will graph the data and then hypothesize about the average speed of the marble going down a one meter ramp.
This resource was reviewed using the Curriki Review rubric and received an overall Curriki Review System rating of 3, as of 2013-08-05.
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.
