小狐生物实验室 vs Pocket Experiments Science Lab

小狐生物实验室是一款面向中学生、homeschool 家庭和科学进阶学习者的可视化生物学习 App。 App 不是静态百科，也不是刷题工具，而是把生物概念做成可以动手操作的互动实验。学生可以在模拟实验台中观察细胞结构、完成 DNA 碱基配对、理解身体系统中的物质流动，并通过食物网模拟观察生态系统的平衡变化。 首版包含多个互动模块： Cell Explorer 探索动物细胞和植物细胞，点选 nucleus、membrane、mitochondria、chloroplast 等结构，理解它们的功能和差异。 DNA Builder 通过 A-T、C-G 碱基配对规则完成互补链，理解 DNA、gene 和 trait 的基础关系。 Body System Flow 观察氧气、血液和营养物质在 respiratory、circulatory、digestive system 中的路径，理解人体系统如何协作。 Food Web Simulator 调节 producer、consumer 和 predator 的数量，观察能量流、种群变化和生态平衡。 Microscope Mode 模拟显微镜观察，调节放大倍数、焦距、光照和载玻片位置，理解显微观察中的视野变化。 小狐生物实验室属于 iFox Science Lab 系列，延续小狐物理实验室的可视化、交互式学习方式，让抽象科学概念更容易被看见、操作和理解。 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.
