In this project, we're creating and disseminating "SmartGraphs," digital objects that "know" about themselves and that provide scaffolding to students to help them learn about graphs and the concepts graphs convey, in mathematics, science and other subjects.
Custom-made parachutes helped the Mars Exploration Rovers Spirit and Opportunity touch down safely on the Red Planet. In this interactive, learn how engineers build chutes that are strong, stable, and compact. Then design your own parachute and test it out in our virtual wind tunnel.
