This entry is way overdue and has been sitting waiting to be posted for-ev-er! Love the predictions/possible outcome ideas of what the children will think will happen when salt or sand is added to a block of ice. We predicted, waited an hour, and then made some excellent observations of what we could see and feel. The results on the block of ice are a little tricky to see but the salt is on the left and the sand is on the right. A great discussion of sand/salt trucks followed on the footsteps of this experiment.
