Understand the influence on scientific knowledge of developments in technology. Sticky Situation Student Activity Better Beads Student Activity Invisible Analysis Student Activity Continuous Collection Student Text Exploration Students will complete three hands-on activities that give them an experience in modeling solar wind collection. A text relates general procedures of various collection techniques. Students choose wafer shapes from the Briefing activity and use hexagons to model the design of the Genesis solar collector. Students will test the collectors by measuring the mass of sand they collect.
Students use ultra violet sensitive beads to represent wafer material and solar wind particles.
Students will discover that all materials collect all solar wind materials, yet some materials allow for better analysis on certain regimes of solar wind than others. Wafer collectors will be designed to withstand an impact should the planned recovery system fail. It's a Hit Student Activity Micrometeroids are a possible contamination problem for the Genesis mission. Development Students will conduct a laboratory investigation to develop their understanding of contamination issues related to collecting solar wind. Students will investigate contamination issues related to collecting solar wind.
