we recorded our first data today...its beenfive days since we began the experiment. as expected, the lower pH levels, 2,3,4 showed the greatest change..they changed on average between .3 and .9 grams however, in several instances, pH solution between 5,6,7,8,9, and 10 actually went up. they actualy increased by about .1 grams...we are unable to explain this now, but we did notice buffer residue collected on some rocks...this may have added weight...we will take another reading later this week
