Objective: The experimental objective of this lab is to design and build a container that minimizes the heat lost by an egg placed inside. The heat loss will be measured by recording the temperature of the surface of the egg. Furthermore, you will learn about heat as a form of energy (thermal energy) and how it is transferred. We will also investigate the principles of minimal design. Your design will be entered in a competition against the other containers in your section. The team with the lowest Minimal Design Ratio (MDR) will be declared the winner.

In 2007, meteor Billy1987 collided with the International Space Station (ISS). The ISS orbits the moon and is a research facility assembled in space and formed among the space agencies of the US, Russia, Japan, Canada and eleven European countries. During the collision, several pieces of the ISS landed on the Moon, including "Zarya", the power supply module. NASA has issued an RFP for the development of a cost-effective autonomous robot that will retrieve Zarya. The robot should be compact in size in order to fit into the space shuttle. It will be released from the shuttle, land on the moon, traverse through the debris, retrieve Zarya, and return back to its landing site where it will take off back to the space shuttle.
