Our camp leaders then 7)(decided) to bring us to the laboratory, and we 8)(made) eggshell geode crystals instead. Well, you know that I 9)(have done) a lot of different experiments in my life, but this one 10)(was) truly cool, and unlike my chemistry experiments gone wrong, nothing11)(exploded). The world of science sure 12)(has changed) a lot in the last few years! 13) (Have you heard) about the discovery of water on Mars? Last August the Mars Orbiter 14)(used) an imaging spectrometer and 15)(detected) presence of hydrated minerals. This confirmed what NASA 16)(had suspected)! We 17)(have learnt) so much about our Solar System since we first 18)(landed) on the Moon and these are things that 19)(seemed) impossible to study just one hundred years back! This 20)(is) such an amazing opportunity and I love every minute.
