Virtual Lab
Animated experiments you can run again, safely, in both languages.
What it is
a virtual lab of animated chemistry experiments you can run without a single chemical. Drop an alkali metal in water — choose lithium, sodium, potassium, rubidium or caesium and watch the reaction grow fiercer down the group. Hold salts in a flame and watch the colour each metal paints there. Set an iron nail in copper sulfate solution and watch displacement happen frame by frame. Every experiment narrates its steps in both languages and closes with the balanced equation your exam expects.
Why it helps you study
Bangladeshi school labs are crowded, and the same three experiments carry huge exam weight — alkali metals and water, flame tests, and iron displacing copper. Here you can run each one as many times as curiosity takes you, change the metal and watch again, and read the narration until every step makes sense. The equations are no longer lines to memorise: you watch them happen, then write them down. Safety goggles not required.
How to use it
- Open the virtual lab and choose an experiment.
- Pick your metal or salt — caesium, for example, for the wildest water reaction.
- Watch the animation and follow the step-by-step narration on screen.
- Read the balanced equation the experiment ends with.
- Switch language and run it again to learn the terms in both.
Questions students ask
Is this a real laboratory or a simulation?
It is a fully animated simulation — no chemicals, no flames and no risk — designed to mirror the NCTB practical experiments step by step.
Will I still get the exam equations?
Yes — every experiment finishes with its balanced equation, written exactly the way your NCTB exam answer will expect it.
