1. What is the earliest evidence?Bone skates, circa 3rd millennium BCE
2. What is the ice skate melting principle?Pressure melting lowers ice's melting point
3. What are skates and how do they help people move on ice?Skates are shoes with a thin, smooth blade that lets you glide across ice. The blade slides easily, so you can move faster than walking.
4. Why did people start using metal blades instead of bone?Metal blades were stronger and gave better control and speed. They were especially useful on icy canals in the Netherlands.

Rolling Friction: The resistance encountered when a round object rolls over a surface.
Rocker (Ice Skate): The curved shape of an ice skate blade, affecting turning radius and agility.
Universal Plate: A component on roller skates allowing for adjustable wheel angles and improved turning.
