Sun from the Planet Walk at the Montshire Museum of Science.
Engineering with the Sun!
This series of activities uses the heat energy from the Sun to make things melt. Test how different items melt on a hot day and challenge yourself to design a cooker for a tasty treat or design a structure to keep an ice cube from melting on a hot day. Put on your inventor and engineering hats to design, build, test, rebuild and test again until you come up with a fantastic solution.
Sometimes it is important to figure out how to keep things cool on a hot day.
In this experiment and engineering challenge you are going to design a way to keep an ice cube from melting.
