TOOLS & INTERACTIVES
Chemistry Learning Lab
GUIDED LEARNING
酸碱与滴定
Acids, Bases & Titration
Student Work by Oliver Qiao · 8 modules · three learning paths · quizzes and browser-local progress.
CLASSROOM SIMULATIONS
Observe, change, explain.
Particle Motion & Collisions
粒子运动与碰撞
Change particle number, temperature, and relative mass to compare motion and collisions.
Atomic Radius Comparator
原子半径比较器
Compare main-group elements using electron shells, a simplified Zeff model, and reference radii.
Ionization Energy & Electron Affinity
电离能与电子亲和能
Add or remove electrons to connect ionic charge, shell structure, and qualitative energy changes.
CHEMISTRY GAMES
Recall, match, repeat.
Molecular Gallery
分子结构探索
Draw structures, collect selected isomers and challenge optional Guardians across five galleries. AI conversations and 3D missions are unavailable.
The Midnight Alarm
午夜警报 · 实验室调查
Examine fictional case exhibits, select observations, interview students and write your case report. An educational reconstruction, not real incident guidance.
Periodic Candy
元素周期表糖果拼图
Arrange elements in periodic-table order, pop pieces for candy, and save your mosaic. Four levels for 1–4 players taking turns on one device.
Molecule Racers
分子赛跑
Build carbon skeletons, identify functional groups, and race with 2–4 players on one device. Game motion is not a physical chemistry model.
Element Symbol Matching
元素符号配对
Match symbols and English names from the first 20 elements in three deck sizes.
Solubility Laboratory
溶解性实验室
Classify ionic compounds as soluble, sparingly soluble, or insoluble and review the governing rule.
Chemical Formula Match
化学式命名配对
Practice five reviewed inorganic naming systems in no-repeat rounds.
