For the past few weeks, the 4th and 5th grade classes at Stuart Mesa have been building roller coasters in the STEM Lab, using mini K'Nex kits. I was able to purchase the kits for the STEM Lab with a grant from Genentech and the Oceanside Chamber of Commerce. Building the roller coasters has been a fantastic experience for the students so far! There have been moments of frustration, perseverance, and celebration amongst the students. Some students even discovered a building talent which they didn't know they had!
The science concepts that we've been focusing on with this unit are some basic physics topics - kinetic and potential energy, gravity, inertia, friction, etc. We have also focused on math concepts, such as finding the mean speed of your roller coaster, measuring the track length, and the height.
