at the national building museum homeschool day in june:
in Roller Coaster Rally signGirl and prayerGirl discovered the physics behind roller coaster design.
in teams, they rotated through four stations building a roller coaster to meet a specific challenge that focused on kinetic energy, potential energy, friction, or some combination of the three.
in Think Global, Build Local mercyGirl learned what makes a home environmentally sustainable by investigating green homes from the past and present, including various technologies and materials that help make each home suitable for its geographic region.
the green features of mercyGirl’s custom building include solar panels, a slanted roof to capture rain water in a rain barrel, and other features that aid in air circulation and heat gain during the winter months.
