We tested our walls with the demolition ball.  Some groups walls started to break apart after 2 to 3 hits.  A couple of groups made it to the level 4 with 4 hits at that level.  We then analyzed all the walls and talked about what made those successful.  Both of the groups that made it to the level 4 had a mortar mixture that was 2 clay and one sand.  One group used 4 Tablespoons water and the other group used 3 1/2 Tablespoons.  Both groups used a thick wall design.  We then took the information from our observations and created our redesign for our mortar and wall plan for tomorrow.
