小狐化学实验室 vs Pocket Experiments Science Lab

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/

Twenty-six rooms. Not a workbook — a bench in each one. You set the parts out yourself, turn the knobs, and measure with the instruments. • Hang as many weights as you like anywhere along a balance beam, and even it up • Drag molecules onto the bench and see what they form • Set a magma's silica and the depth where it freezes, erupt it, then look at the rock through a hand lens and measure the grains • Stretch two strings, detune one, and listen to the beats • Drop three seismometers on a map; three circles meet at one point, and that point is the epicenter Every number is measured off the picture. Nothing here works a value out of a formula and then "checks" it against the same formula. The grains under the lens are really drawn, and their size is really measured. Turn a knob and the picture changes; when the picture changes, the numbers change with it. Every room has three steps: 1. Move it — turn one knob and watch what changes 2. Count it — line the measurement up against the formula and look at the gap 3. Check it — one question, and the reason either way Every room also has a question box. Clear it and the room moves up a tier: none → bronze → silver → gold. There are 78 questions in all. But the questions are not the main act. Playing with the bench is; a question is the detour you take when you think “wait — could I actually build that?” The topics are middle school and high school science: forces and motion, springs and buoyancy, pendulums, circuits, electromagnets, ray optics, lenses, sound, changes of state, solubility, titration, electrolysis, chemical reactions, preparing and collecting gases, the microscope, cell division, photosynthesis, flower structure, heredity, strata, rocks and volcanoes, earthquakes, and the sky. Three neighbors of science come along too: probability, logic gates and regular expressions. ADS AND THE ONE-TIME PURCHASE The app is free and shows ads: a banner along the bottom of the screen, and a full-screen ad when you open the app. All 26 rooms and all 78 questions are open from the first launch. There is exactly one in-app purchase and all it does is turn the ads off — it unlocks nothing and adds nothing. It is a single one-time purchase with no subscription (¥5,000 in Japan; the price for your country is shown in the app). Not based on, or affiliated with, any particular textbook.
