20also revisited in this project.. Indeed, as Christa often said, “ITouch the Future. I Teach.” Through the lost live lessons, she willbe teaching once more, though more than a score of years since thatmomentous launch of January 28, 1986. JRW November 2007]
21Challenger’s Live Lost LessonsWH<strong>ER</strong>E WE'VE BEEN, WH<strong>ER</strong>E WE'RE GOING (SECONDLIVE LESSON)On flight day 6, the teacher will conduct two (2) 15 minutelessons broadcast live from the Orbiter. The first, titled "TheUltimate Field Trip," required no special hardware. The goals of thesecond lesson were to better understand why mankind utilizes andexplores space. The objectives were to demonstrate the advantages ofmanufacturing in microgravity, to highlight technologicaladvancements that evolve from the space program, and to projectmankind's future in space. It was particularly desirable that thesedemonstrations could be duplicated in the classroom so that studentscould compare in real time the results of what they did to the spaceactivity.Several demonstrations will be conducted to illustrate thebehavior of materials in microgravity. A sphere of orange juice willbe formed carefully from a drink container. The fact that liquids formperfect spheres in space is useful in forming mono-disperse latexbeads, for instance, which can be used by the Bureau of Standards.Mixing of molecules of different substances will be illustrated usingmarshmallows and chocolate candies in a plastic bag. Mixing ofliquids of differing densities will be demonstrated using salad oil andcolored water sealed in lexan bottles. Two of these containers will beused. One has 1/2 water and 1/2 oil. The other contains 1/3 water, 1/3oil, and 1/3 air. These can be compared to determine how thepresence of the air affects the way the liquids behave. A marble is ineach bottle to stir the mixture. Also, the teacher will use a largequartz crystal to discuss the special conditions conducive to thegrowth of large crystals, especially relating to the growth of crystalsin space. Of course mankind uses space for more than materialsprocessing. This will be illustrated using 8x10 color photographs ofphenomena visible on the Earth from space, but not so apparent onthe ground, or even from aircraft. A photo of a hurricane, a volcanic
