經(jīng)緯度模型 32cm J34009地球經(jīng)緯儀 初中高中學地理儀器 教學儀器
產(chǎn)品概述
經(jīng)緯度模型32cm J34009地球經(jīng)緯儀是一款專為初中和高中地理教學設計的教學儀器，采用32厘米直徑的空心網(wǎng)狀球體結構，由24條經(jīng)線和9條緯線構成，能夠清晰展示地球的經(jīng)緯網(wǎng)系統(tǒng)。該模型配備可調節(jié)的經(jīng)線平面板和緯度指針，幫助學生直觀理解地球自轉、時區(qū)劃分和五帶范圍等地理概念。地軸與底座呈66.5°夾角，符合地球實際傾斜角度，增強教學演示的真實性。138
功能特點
該地球經(jīng)緯儀具有多重教學功能，包括演示地球自轉方向、地軸與兩極關系、本初子午線定位以及赤道平面劃分等。球體內部設有固定式赤道平面板和本初子午線板，通過旋鈕可調整經(jīng)線平面板角度，方便展示不同經(jīng)緯度組合下的地理現(xiàn)象。模型采用金屬支架和環(huán)保材質制作，結構穩(wěn)固耐用，適合課堂反復使用。其320mm的適中尺寸既保證演示清晰度，又便于教室空間擺放。3621
教學應用
在教學實踐中，該儀器能有效輔助講解經(jīng)緯度坐標系統(tǒng)、時區(qū)計算、晝夜更替等核心知識點。教師可通過旋轉經(jīng)線平面板演示不同地區(qū)的晝夜變化，利用緯度指針說明氣候帶分布規(guī)律。網(wǎng)狀球體設計使學生能多角度觀察經(jīng)緯線交匯關系，配合配套的演示標志可開展互動式教學活動，提升學生對地球空間結構的認知能力。適用于地理課堂演示、天文興趣小組活動及科學探究實驗等多種教學場景。31523
產(chǎn)品描述（英文）
The Longitude and Latitude Model (32cm J34009) is an educational instrument designed for secondary school geography teaching. Featuring a 320mm diameter hollow mesh sphere constructed with 24 meridians and 9 parallels, it visually demonstrates the Earth s coordinate system. The model includes adjustable longitude planes and latitude indicators, allowing teachers to illustrate planetary rotation, time zone division, and climate zones. The 66.5° tilt between the axis and base replicates Earth s actual obliquity, enhancing demonstration accuracy.18
With durable metal stand and eco-friendly materials, this teaching aid enables hands-on exploration of geographical principles. Its transparent grid structure facilitates multi-angle observation of longitude/latitude relationships, while rotary controls help simulate diurnal motion and seasonal variations. The medium size ensures clear visibility in classroom settings without occupying excessive space. This instrument serves as an effective tool for interactive learning in physical geography, astronomy clubs, and STEM education programs.321
The design emphasizes pedagogical functionality, omitting complex technical specifications to maintain focus on core geographical concepts. Teachers can utilize attached demonstration markers to create engaging activities about coordinate positioning, map reading, and global spatial relationships. Suitable for students aged 12-18, it complies with general educational equipment requirements for middle and high school curricula.615
