小狐化学实验室 vs Sapling Isle

小狐化学实验室是一款面向中学生的化学实验学习工具，围绕常见中考化学实验，把实验步骤、实验现象、化学方程式、易错点和微观原理整合到一个可交互的学习流程中。 主要功能： 1. 化学实验训练 覆盖制取氧气、制取二氧化碳、粗盐过滤、蒸发结晶、金属活动性、酸碱盐反应等中学常见实验。每个实验包含仪器选择、操作顺序、现象判断和扣分点训练。 2. 实验原理微观分析 用粒子视角解释实验背后的变化，例如过氧化氢分解生成氧气、碳酸盐与酸反应产生二氧化碳、粗盐过滤中的分离过程等，帮助学生从“背结论”走向“理解为什么”。 3. 3D 可视化学 提供轨道杂化、σ键/π键、甲烷空间构型、VSEPR模型、离子晶格溶解等可视化模块，把抽象化学概念变成可以观察和对照理解的模型。 4. 学习进度与错因记录 记录实验掌握情况、练习结果和错因，方便学生复习薄弱环节。 适合： - 初中化学实验复习 - 中考实验操作与实验题训练 - 想用可视化方式理解化学概念的学生 - 家长和老师辅助讲解实验原理 Privacy Policy: http://mindkey.xyz/index.php/mindkey/privacy-policy/ Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Sapling Isle is a multilingual interactive science lab that connects observable phenomena with advanced scientific concepts on iPhone and iPad. Change variables directly, observe how a system responds, read graphs and measurements, then explore the equations, assumptions, and limits behind the model. Explore nature and the universe • Control a 3D Solar System and observe planetary motion and astronomical time • Follow curved light, an accretion disk, and Einstein rings around a black hole Enter a hands-on physics lab • Explore forces, motion, heat, energy, magnetic fields, light, and atoms • Compare heating, compression, and diffusion in a 3D microscopic world • Investigate orbits, waves, entropy, Boltzmann distributions, quantum tunneling, and double-slit patterns Explore at your own depth • Start with direct manipulation and visual feedback • Continue with multivariable comparisons, measurements, and graphs • Go deeper into equations, approximations, and model boundaries • Choose from 10 interface languages • Adaptive layouts for both iPhone and iPad • No account, advertising, or cross-app tracking • Progress, camera frames, and experiment data are handled primarily on device Pick an island, begin with a phenomenon, and follow the evidence toward deeper models.
