How should you make your polar bear diorama?

its weird but im trying to do the same thing for my ecosystem project, first i took a shoe box from an old stack of things i never use, then i bought model magic from Walmart and made plants and animals if this does not work for you try to buy some plastic toy animals from a dollar store,then paint the sides of the box to make it look like the artic,then place the animals into the box any way you like and remember to be creative.Hope this helps you.
