Is the energy contained in a pressure vessel which has been “charged” at the bottom of the ocean, less than, equal, or greater than the energy required to raise the vessel to the surface?	1
Being an incompressible fluid, can water under pressure in a closed system (sealed rigid container) perform work when released from said container?	1
What scientific questions would people be surprised to learn that our current best answers are, “We don’t know?”	1
Why does iron chlorosis only affect part of a tree/plant? Do the nutrients not get equally distributed to all the tree?	1
Understanding that the gravity from the moon causes the tides, what is the energy source that moves the water? i.e. is gravity a form of energy?	1

Are their structural differences in artificial fructose derived from corn and fructose found naturally occurring in fruits and vegetables? If so, what impact do these differences have on the metabolic breakdown of these sugars for energy production?	1
How does the addition of a salt (e.g. NaCl or MgCl) to pure water affect the compressibility of the solution?	1
Do the ice packs (gel packs) used in shipping cold products have different thermal transfer properties than pure water ice? i.e. do they stay colder longer than pure ice in a given environment? If so, how?	1
