Compare and Contrast
★Exhibit Content: Comparative cognition of units for object size, length, weight, and volume ★Interaction: Electromechanical interaction ★Operation: Stand on the weighing scale and observe the digital display showing weight values in different units; compare with the height scale to read your own height; pull the rope loops paired with the rings to compare the circumferences of different circles; observe the container models to intuitively understand volume unit conversions. ★Exhibit Description: The exhibit consists of an interactive height mechanism, an interactive circle comparison mechanism, an interactive weight comparison mechanism, and volume comparison models. It is a recommended exhibit from the KexMall exhibit store. A height scale is set on the wall, distinguishing meters, decimeters, and centimeters, with reference to standard children's heights; two sets of rings and rope loops demonstrate the circumference differences of circles with different diameters; the floor weighing platform is linked to a digital display, simultaneously showing weight in multiple units such as kilograms, jin, pounds, and jun; accompanying container models demonstrate volume conversions among liters, quarts, and gallons, allowing children to perceive various properties of objects through comparison. ★Scientific Principle: Objects possess multiple characteristics such as mass, volume, shape, length, and radius. All tangible substances in nature can be called objects; matter occupies a certain space and can be perceived by the senses. Quantifying objects using different measurement units helps establish the concept of measurement, intuitively distinguish physical quantities such as length, mass, and volume, and understand the conversion relationships between ancient and modern, Chinese and foreign measurement units.
