What do we need to make this thing?
Plastic is required to make the Lego bricks, cardboard for the boxes, paper for the instruction manuals (in some cases) and plastic bags to keep them from spilling while trucks are taking it to the mall or the distribution center.

What is the process?
First, A truck grabs tiny little granules and gets into tall circles called “silos” which look like a drinking glass but it's metal and much bigger. Different types of granules are in different colours for each type of design. Lego wheels require granules coloured black.

When it's ready to make the Lego, the granules are removed from the silos and are melted into liquid which is not really tasty. Then it goes into a very complex machine which molds them with extreme force. Molding is when the machines get the liquid to harden and be shipshape in a certain shape.

Then the Lego bricks stay in a huge storage area and robots take them to places where grown-ups like your mum/mom and dad sort the items block by block. The now-sorted stuff go to big trucks that take it to “distribution centres” where the big trucks come in, they keep all of the toys and then smaller trucks often leave the distribution centers.

Then the small trucks go to malls before your mom prepares you for a Lego shopping trip and deliver the Lego sets. Now it's there. An hour or two later you're in the mall and you buy the Lego. And when you get home you're all set for playtime!
