Astronomy class.

The Mars project was really fun. They had to create an artificial ecosystem to be able to live in. All they had to work with, were boxes, masking tape, aluminum foil, and plastic containers... and this is what they made with their friends!!.They are covering their mouths, because they are outside and there is NO OXYGEN!!. It has solar panels and windows to look out into space! ,and it is REALLY big!!!.. it takes over my basement!
