34009經(jīng)緯度模型320mm 地理教學(xué)儀器
產(chǎn)品概述
34009經(jīng)緯度模型是一款專為中學(xué)地理教學(xué)設(shè)計(jì)的演示儀器，采用直徑320mm的球體結(jié)構(gòu)，直觀展示地球自轉(zhuǎn)、地軸、兩極、經(jīng)緯線及經(jīng)緯度等地理概念。該模型由24條經(jīng)線和9條緯線構(gòu)成空心網(wǎng)狀球體，內(nèi)部設(shè)有可調(diào)節(jié)的本初子午線平面板、赤道平面板及緯度指針，通過旋鈕控制實(shí)現(xiàn)動(dòng)態(tài)演示。地軸與底座呈66.5°夾角，符合地球?qū)嶋H傾角，并附帶時(shí)區(qū)演示套圈，適用于初中、高中地理課堂的互動(dòng)教學(xué)。5813
核心功能
模型通過旋轉(zhuǎn)經(jīng)線平面板和緯度指針，可清晰演示地球自轉(zhuǎn)方向、理論時(shí)區(qū)劃分、國(guó)際日期變更線及五帶范圍等知識(shí)點(diǎn)。球體采用輕質(zhì)耐用材質(zhì)，支架穩(wěn)固，便于教師操作和學(xué)生觀察。其空心網(wǎng)狀設(shè)計(jì)能立體呈現(xiàn)經(jīng)緯網(wǎng)系統(tǒng)，幫助學(xué)生理解地理坐標(biāo)的定位原理，同時(shí)支持晝夜更替、季節(jié)變化等拓展內(nèi)容的模擬教學(xué)。5815
教學(xué)價(jià)值
作為地理課堂的重要教具，該模型將抽象的地球運(yùn)動(dòng)轉(zhuǎn)化為可視化演示，增強(qiáng)學(xué)生對(duì)黃赤交角、極晝極夜等現(xiàn)象的認(rèn)知。其標(biāo)準(zhǔn)化尺寸（320mm）適合教室多角度觀察，且符合國(guó)家教育儀器配備要求，廣泛應(yīng)用于初中、高中地理實(shí)驗(yàn)室和專用教室。111316
Product Overview
The 34009 Longitude-Latitude Model is a 320mm-diameter teaching instrument designed for secondary school geography education. It features a hollow spherical framework composed of 24 meridians and 9 parallels, with adjustable prime meridian plate, equatorial plate, and latitude pointer inside. The 66.5° tilt axis replicates Earth s actual obliquity, while detachable rings demonstrate time zone divisions. Ideal for interactive lessons on planetary rotation and spatial coordinate systems.81318
Key Features
This model dynamically illustrates Earth s rotation, time zone calculations, and climate zones through manual adjustments of its internal components. The lightweight mesh structure ensures durability, and the stable stand allows 360° classroom viewing. Its open-grid design visually explains longitude/latitude positioning, with optional extensions for day-night cycles and seasonal changes. Suitable for group activities and teacher-guided demonstrations.5815
Educational Benefits
By transforming abstract astronomical concepts into tangible interactions, the model enhances comprehension of equator-polar relationships and solar term phenomena. Compatible with standard geography curricula, it serves as an essential tool for middle and high school labs, fostering hands-on learning in physical geography.111316
