Song of the Month
"Down by the Bay"
Down by the bay
Where the watermelons grow
Back to my home I dare not go
For if I do
My mother will say
"Did you ever you ever see a goose kissing a moose?"
Why do some things float and others sink? The first thing that comes to mind for many people is that it depends on how heavy an object is. Mass matters, but there is more to it. The ability of an object to float is described as its buoyancy. The buoyancy of an object is its tendency to float on or rise in a liquid. An object that floats in water is said to be positively buoyant. An object that sinks is negatively buoyant. To determine an object's buoyancy, both its mass and volume* must be taken into consideration.
The development of mathematical knowledge and skills contributes to children’s ability to make sense of the world and to solve problems they encounter in their everyday lives. Knowledge of basic math concepts and the skill to use math operations to solve problems are fundamental aspects of school readiness and are predictive of later success in school and in life.
