To complement a unit on habitats and biomes, I created this lesson for Minecraft. The students created homes for a variety of biomes, considering the animals and materials in the areas.
I pushed them to consider to advantages/disadvantages of building on the ground or in the ground, in trees or in caves, in water or on the water, etc.
Admittedly, the students wanted to create extremely fancy homes. So, I would encourage you to preview the types of materials in the areas and give them a bank from which to choose; otherwise, someone will build a diamond block home with gold flooring.
