It describes how riders glide down snowy mountains, using friction to melt snow into a thin film of water that enables sliding, and how board design helps withstand stresses and cold. The chapter connects balance, center of gravity, and gravity-driven motion during jumps, including how helmet-mounted cameras capture aerial

ONTHE SLOPES\n\nhe snowboarders glide downthe snowy mountain.As theycarve new paths in the powder,  \nthey are actually sliding over a thin filmof water.The friction of their boardsmelts the snow,creating this water.Theboards have been skillfully engineered towithstand stresses and cold temperatures.The snowboarders shift their positionsas they ride.Maintaining their balancetakes practice and skill.They make tinyadjustments to keep their center of gravityover the board.The snowboarders reach a  \njump,and one after another they go airborne.As soonas they leave the ramp,gravity begins pulling themback to Earth.While spinning in the air,they travel ina smooth arc back down to the slope.A tiny camerastrapped to one of the snowboarders'helmets capturesall the action.  \nSnowboarding can be fun and exciting.Somesnowboarders zoom down mountainsides,slicingthrough the snow.Others catch huge air on jumps,pulling off impressive tricks.Underlying all of thesethrills are principles of STEM(science,technology,engineering,and math).  \n# FROM SNURFINGTO SNOWBOARDING\n\nAn engineer named Sherman Poppen inventedsnowboarding in the 1960s.His first snowboard wasjust two skis fastened together.There was a rope onone end to help the rider steer.Poppen's wife,Nancy,called this first board a\"snurfer\"because it seemedlike a mixture
