It was the perfect day for a wall walk! The sun was shining, summer like temperatures, and students were ready to observe different types of walls. We walked around the RES/CHMS campus looking for four different types of walls-and we found some! Students had to make scientific drawings of these walls, including labels of what they believed the wall was made out of, and what the mortar was made out of (if any). In upcoming days, students will be engineering their own miniature walls; exploring with different mortar mixtures.
