Educational Value of Metal Casting

Metal Casting takes students on a journey from raw material to finished product, experiencing one of humanity's most transformative technologies. When students watch solid metal become liquid and then solidify into a new shape, they witness phase changes, thermal energy transfer, and materials science in action.

Why Do Metals Melt at Different Temperatures?

Every metal has atoms bonded together with a specific strength. Pewter melts at only 230°C because its atoms are loosely bonded. Aluminum requires 660°C. Bronze (copper + tin) needs 900-1000°C because copper atoms bond very strongly. When we add enough thermal energy to overcome these atomic bonds, the metal transitions from solid to liquid.

MS-PS3-4 Plan an investigation to determine the relationships among energy transferred, type of matter, mass, and change in kinetic energy. Investigate: Does a larger piece of metal take longer to melt? How does mass affect energy needed?
