Igloo Building STEM Challenge

One of my favorite winter activities ever is building a sugar cube igloo... it's a classic! This week my third graders took on the challenge.
We started with some conversation about igloos and their purpose. We did a little research and found out that the igloo must be made with ice bricks that lean in a little. This was important to our building.
Next, we prepared our materials. Each group was given one box of "ice blocks" (sugar cubes) and a cup of icing. We used Popsicle sticks as our tools.

Finally, the kids got to work! You would be shocked at how difficult this challenge really can be!
Next week we will continue with more winter themed STEM challenges!
