Lego is the latest company to try mass customization. Every brick of every Lego set that will end up in the hands of any kid in North America passes through this mammoth facility, nestled among farms and three state prisons.
A conceptual module expresses an idea about how a system works. Examples of systems include an atom, a cell, a river delta, or a planet. The interlocking plastic bricks can be assembled into an endless variety of objects see Figure 1.
Some kids and even many adults are interested in building the perfect model — finding the bricks of the right color, shape, and size, and assembling them into a replica of a familiar object in the real world, like a castle, the space shuttleor London Bridge.
Others focus on using the object they build — moving LEGO knights in and out of the castle shown in Figure 1, for example, or enacting a space shuttle mission to Mars. Still others may have no particular end product in mind when they start snapping bricks together and just want to see what they can do with the pieces they have.
On the most basic level, scientists use models in much the same way that people play with LEGO bricks. Scientific models may or may not be physical entities, but scientists build them for the same variety of reasons: Physical, conceptual, mathematical At the St.
Anthony Falls Laboratory at the University of Minnesota, a group of engineers and geologists have built a room-sized physical replica of a river delta to model a real one like the Mississippi River delta in the Gulf of Mexico Paola et al. These researchers have successfully incorporated into their model the key processes that control river deltas like the variability of water flow, the deposition of sediments transported by the river, and the compaction and subsidence of the coastline under the pressure of constant sediment additions in order to better understand how those processes interact.
With their physical model, they can mimic the general setting of the Mississippi River delta and then do things they can't do in the real world, like take a slice through the resulting sedimentary deposits to analyze the layers within the sediments.
Or they can experiment with changing parameters like sea level and sedimentary input to see how those changes affect deposition of sediments within the delta, the same way you might "experiment" with the placement of the knights in your LEGO castle.

Some are conceptual, and involve assembling all of the known components of a system into a coherent whole. This is a little like building an abstract sculpture out of LEGO bricks rather than building a castle.
For example, over the past several hundred years, scientists have developed a series of models for the structure of an atom. The earliest known model of the atom compared it to a billiard ball, reflecting what scientists knew at the time — they were the smallest piece of an element that maintained the properties of that element.
Despite the fact that this was a purely conceptual model, it could be used to predict some of the behavior that atoms exhibit. However, it did not explain all of the properties of atoms accurately. With the discovery of subatomic particles like the proton and electronthe physicist Ernest Rutherford proposed a "solar system" model of the atom, in which electrons orbited around a nucleus that included protons see our Atomic Theory I: The Early Days module for more information.
While the Rutherford model is useful for understanding basic properties of atoms, it eventually proved insufficient to explain all of the behavior of atoms. The current quantum model of the atom depicts electrons not as pure particles, but as having the properties of both particles and wavesand these electrons are located in specific probability density clouds around the atom's nucleus.
Both physical and conceptual models continue to be important components of scientific research. In addition, many scientists now build models mathematically through computer programming.Both children and adults are easily captivated by the world of Minecraft.
It’s like discovering a limitless container of Lego blocks. The open sandbox format of this game makes absolutely anything possible. Learning Computational Thinking and scratch at distance.

In , the company took its first step towards these goals by introducing plastic blocks made of plant-based materials – in the shape of plants.
The company announced the introduction of sustainable LEGO blocks in March this year.
