Igloos are cool. You can easily build an milk jug igloo in your classroom with some planning, lots of milk jugs, and hot glue.

For example, children at Midland Christian School in Midland, Michigan built the 428-jug igloo (shown above) after collecting and cleaning milk cartons for about three weeks. This medium-sized igloo is large enough to hold about 8 to 10 kindergardeners or first graders during free reading time—and a principal fits in there too!

Total cost: about $12 for 80 glue sticks. The milk jug igloo provides all sorts of opportunities for links to social studies, math, science and reading topics (many of which are listed below).

A milk jug igloo is a great project for a classroom, nature center, library, Vacation Bible School, children's museum, daycare center, recycling center, or dozens of other places that seek to inspire children.
