When we started designing our STEAM Room we knew that it had to contain a Lego Wall. Other makerspaces have used Lego walls to great success with their students both for fun as well as for the critical thinking skills they require. We decided to build ours over the old "ghost door"at the back of the portable using a couple of heavy boards for mounting the green panels. It took several days of measuring, sanding and gluing, but it was worth the effort. Now that the glue has dried this wall is ready for some serious creativity. What will you build?
