Find your sticks and discuss today's lab activity. Discuss your set up. What factors will you have to control to make sure you are testing only the right variables? What factor(s) will be the biggest sources of error? Which will be the most difficult to control? What will you do to minimize the potential error?
Learning Goal: To understand the relationship between work and energy, and use it to predict the motion of objects
Today: Blowdart Challenge!
Given: Q-tips, large diameter straws, tape, metersticks or metric tape measures, timing devices
Find: Determine the relationship between the length of the straw and the exit speed of the dart. Support your conclusions with data tables and graphs.
Extension: Calculate the acceleration of the Q-tip in the straw and the time the Q-tip spends within the straw.
