Our school is close to completing its 1:1 initiative where we have given each student in grades 3-5 a Chromebook to use. (Grades K-2 use iPads primarily.) With this in place we really did not need our traditional computer lab anymore.
An additional motivating factor for me occurred during the summer. I attended Constructing Modern Knowledge, a professional learning conference organized by Gary Stager, and felt that a makerspace environment would be perfect for the room.
Following advice from an ISTE article, I jumped in and decided to start with what we had in creating this new makerspace.
The physical changes I made in the room were enough to get the "What happened?" reaction I wanted, but I also wanted to have the students' first activity be something totally different than anything they had done in the former computer lab.
The activity for grades 1-5 was borrowed from a post I saw on Twitter. Working in small groups, students received a paper bag with 10 random items in it (from my basement). The groups' task was to create something out of all the items. I also allowed students to use additional supplies. The entire activity was framed around the cooking show Chopped.
While no team was eliminated and no winner was declared, the students immediately jumped into the activity with great enthusiasm. By the end of this maker version of Chopped, I believe I had succeeded in my goal...things were going to be different.
