This team minimized conduction (heat moving between two objects) by containing the cube inside a zip lock baggie while insulating it with foam, tin foil, and platic wrap. They also put a layer of salt with ice outside the insulation in an attempt to lower the freezing point of water. The materials slowed conduction. The box was freezing to the touch when opened!!
a tin soup can wrapped with ice packs and duck tape!!
This group is using a compact space to see how it influences the melting rate of their cube.
This student is trying to use plastics to insulate their cube.
This group used tin foil to keep their cube insulated.
Groups are trying to maintain a constant temperature inside a student made device for 24 hours. The goal is to keep an ice cube in its solid state for 24 hours. Students are using substances that retain energy and keep thermal energy from entering their chamber.
Thermal energy can refer to several distinct thermodynamic quantities, such as the internal energy of a system; heat or sensible heat, which are defined as types of transfer of energy; or for the characteristic energy of a degree of freedom in a thermal system, where is temperature and is the Boltzmann constant.

We attached a fan and a light bulb to our bike. We made it so the fan and light bulb would power at the same time.
This car was made by a group of boys. They are working hard to create a wind powered car!
In science the kids are making a boat with energy from a propeller. The propeller is acting as a motor. The boat will move in water like a real boat.
Changing the world one satellite at a time!
