A Science learning game for primary school, Grade 3 to Grade 6
Niki's Lab is a science experiment game for grade 3 through grade 6. The child predicts first — will this bulb light up? will the magnet pull this spoon? — then the experiment runs on the table and they see the result themselves. Even a wrong guess leads to seeing the right answer.
The Android app is on Cafe Bazaar and Myket, Iran's app stores. Anywhere else, play the online version in any browser.
Niki's Lab is part of the Nikipoo School app, alongside 85 other games. The game is in Persian.
The Lab is for grades 3 through 6 and brings the science textbook's “think, experiment, observe” cycle to a tabletop experiment. The child predicts first — will the magnet pull this spoon? will this bulb light up? — then the experiment runs before their eyes and they see the result. Sometimes they place the battery, wire, and bulb together themselves and build a circuit. The topics are magnets and poles, dissolving and separating mixtures, series and parallel circuits, electromagnets, friction, levers, and seesaws.
Predicting before the experiment is exactly a “hypothesis”: a guess that can be tested. The child learns to think first, pick their guess, and then compare it against the evidence. This mental habit is the core of scientific thinking, and in other subjects too it keeps the child from accepting a claim without reason.
When a prediction doesn't come true, the game just says “the experiment showed something else!” and shows that same truth. The child experiences that scientists guess wrong too, and that those very guesses lead them to discovery; an outlook that lessens the fear of being wrong.
Building a circuit with their own hands, seeing both bulbs go dark in a series circuit, or moving a lever's fulcrum takes the child from “what happens” to “why it happens.” They discover how the parts of a system relate to each other, a foundation for understanding the devices they deal with at home every day.
In levels like “smooth surface, rough surface” or “more turns of wire,” one factor changes and its effect is seen. Without knowing its name, the child becomes familiar with the idea of a “variable”: to see the effect of one thing, you change only that and keep the rest the same.
A tip for parentsGather a fridge magnet and a few small things like a paperclip, a coin, a spoon, and a bottle cap. Before each test, ask the child “do you think it'll stick?” and write down their guess; then test it together and mark the result next to the guess.
