How are Mass and Weight different?
Mass is the measure of the amount of matter in something, weight is is a measure of how the force of gravity acts upon that mass
If the buoyant force is equal to the object’s weight, it will....
FLOAT

What do you feel when you swim down to the bottom of a deep pool or lake? Why?
The pressure increases.
How does Gravity differ on the Moon than on Earth?
Gravity is less on the Moon than on Earth *You weigh less on the Moon than on Earth*
During the "Mini Lab" on last Thursday the Egg floated in Salt water and not in Tap water ..... why?
Because the Buoyant Force is heavier and pushes up on the Egg. *the salt water is heavier*
