A scale model is a smaller version of something, like a toy car or dollhouse. Imagine you have a big toy car that measures one foot long. If you make a scale model of the same car but at 1/10 the size, the model car would be only one inch long!
Scale models can be as small or as big as you like but they need to be proportional to the real thing. This means that the measurements of the scale model should be a smaller or larger version of the actual object being modeled. It's like using a shrink ray to make something small or a giant ray to make something big!
People build scale models of things like buildings, airplanes, and even cities! These models can be used to plan out new buildings, test designs or just for fun. So, next time you see a tiny toy car, you'll know it's a scale model!
