In this lab activity, students will become materials scientists for a day. Working with NASA to design a satellite or a rover means understanding the properties of metals under conditions very unlike those on Earth. Which material should we use to construct a rover going to a planet like Venus? What if we were traveling to an icy planet or even underwater? The answer can be found in chemistry! Materials Small test tubes and a test tube rack 1-2 pieces of zinc pellets 1-2 pieces of lead shot 1-2
