【地理教學(xué)經(jīng)緯度演示模型 產(chǎn)品介紹】
中文學(xué)術(shù)版：
本地理教學(xué)演示模型專為中小學(xué)地理課堂設(shè)計(jì)，采用立體化結(jié)構(gòu)直觀展示地球坐標(biāo)系原理。模型主體由耐磨損ABS工程塑料打造，以1:8500萬(wàn)比例科學(xué)還原地球形態(tài)，表面精確標(biāo)注經(jīng)度、緯度網(wǎng)格及重要地理分界線。主體球體直徑32cm，通過(guò)可調(diào)節(jié)支架實(shí)現(xiàn)23.5°傾斜角模擬，配套磁吸式晨昏線組件可動(dòng)態(tài)演示晝夜更替現(xiàn)象。
模型配置有雙層旋轉(zhuǎn)結(jié)構(gòu)，外層透明亞克力經(jīng)緯網(wǎng)框架與內(nèi)層地形球體可分離操作，支持師生互動(dòng)式探究經(jīng)緯線劃分規(guī)律。配備12組可替換標(biāo)識(shí)模塊，涵蓋回歸線、極圈、時(shí)區(qū)劃分等教學(xué)重點(diǎn)，卡扣式設(shè)計(jì)便于課堂快速切換教學(xué)場(chǎng)景。底座集成角度刻度盤(pán)與方位指示器，可配合教具進(jìn)行太陽(yáng)高度角測(cè)算、地方時(shí)推算等實(shí)踐活動(dòng)。
該教具嚴(yán)格遵循地理課程標(biāo)準(zhǔn)要求，通過(guò)觸覺(jué)感知與視覺(jué)觀察相結(jié)合的方式，有效輔助"地球運(yùn)動(dòng)"、"地理坐標(biāo)"等教學(xué)難點(diǎn)突破。模塊化設(shè)計(jì)便于分組實(shí)驗(yàn)操作，增強(qiáng)學(xué)生空間思維能力和地理實(shí)踐力，配套教學(xué)指南含6種標(biāo)準(zhǔn)化課堂活動(dòng)方案。
English Version:
This geographic coordinate demonstration model is designed for middle school geography classrooms, featuring a three-dimensional structure that visually explains the principles of Earth s coordinate system. The main body, constructed from durable ABS engineering plastic, accurately represents Earth s form at a 1:85 million scale with precisely marked longitude and latitude grids.
The 32cm diameter sphere is mounted on an adjustable tilting stand simulating 23.5° axial tilt. Magnetic day-night terminator components enable dynamic demonstration of diurnal cycles. The innovative dual-layer rotating system combines a transparent acrylic coordinate frame with detachable topographic sphere, allowing interactive exploration of geographic grid systems.
Twelve interchangeable marker modules cover key curriculum elements including tropics, polar circles, and time zones, with snap-on design for quick scenario changes. The base integrates angular measurement scales and directional indicators, supporting practical activities like solar altitude calculation and local time conversion.
Developed in alignment with geography education standards, this teaching aid enhances spatial cognition through tactile-visual learning experiences. Its modular configuration facilitates group experiments and develops students geographic practice skills. The package includes six structured classroom activity guides for effective implementation of coordinate system studies and Earth motion demonstrations.
