Today in science the students learned about the sum of all parts.  There were two experiments that they performed.  The first had them take some salt and put it in a cup and weigh it.  Then they added water to it and weighed it again. The cups were then put aside for later.
The second experiment was to take a bag of Legos and weigh them.  Then they built a house with the pieces and weighed the house.  It appears that the house weighs the same as the bag of Legos.
Hmmmmmm.  I wonder if the same will happen with the salt?  I guess we'll find out in about a week or so, when we will do Part II of this experiment.
