Balance

2nd grade students are studying balance in science.  We are learning what the word balance means.  Another word we are learning about is stable.  Last week we discussed counterbalance.  Some students wondered if that meant getting on top of a counter and balancing something, but it actually means to add weight to an object to make it balance.  We used clothes pins to add weight to the cardboard crayfish and it made it so we could balance the crayfish more easily.  We found out that by changing where the clothespins were attached we could balance the crayfish in different places.
