General Science: The Right Stuff
This week the kids had to design a spacesuit that could withstand the intensely high temperatures one might find on Venus. Lacking the funding to actually travel to Venus and not wanting to violate the Helsinki Declaration (ethical principles for research on human subjects), we used ice-pops instead of people and hot water instead of Venus. The kids made spacesuits using one of three available materials: tin foil, cotton balls, and bubble wrap. Each of the subjects was then placed in a plastic bag and then then submerged in hot water for 1 minute. Afterward, the kids opened up each ice-pop and measured how much of it had melted by pouring the liquid from each one into a graduated cylinder.
