Questioning is a highly effective strategy that has the potential to successfully engage students. Questioning a particular student about an aspect of a lesson prompts the attention of that student as well as most of the students in close proximity.
Food scientist Vickie Kloeris makes meals for astronauts. Vickie Kloeris' job is to feed those astronauts. As one of NASA's top food scientists, she manages the agency's food laboratory as well as the ISS's food system, making sure everyone onboard has plenty to eat and a varying menu.
Of course there was no water in the food at all, and while some things, like fruit could just be eaten dry, other foods needed to be mixed with water to make them edible. To prepare their meals, astronauts squeezed water into the packet of food, with a water gun, and then ate the moist food after a few minutes.
