Which do you think would have the greater mass and greater volume? Why? 1 kg of rock 1 kg of feathers.

DENSITY. Density is the measure of mass per unit volume of substance. So, density is a measure of the amount of matter (particles) in a given volume (space)

Mass - the amount of matter in a substance -depends on the number and size of particles making up that substance -the same wherever it is measured Mass.

Floating and Sinking.  Density is a measure of how closely packed the atoms in a substance are  Density is a physical property  All matter has measurable.

1. What is Density?  A. Amount of atoms (mass) divided by the space (volume) they take up, M/V.

DENSITY AND BUOYANCY OBJECTIVE: to learn how to predict whether an object will float or sink.

Experiment 6.13 (P.142) ObjectMass(g)volumedensity Iron Aluminium Cork

Experiment 6.13 (P.142) 3. Arrange the objects in ascending order of density. __________________________ Cork, Aluminium, Iron

Sinking and floating (P.144) An object floats or sinks depends on its density.

Activity Corner C (P.144) 1(a) Polystyrene, oil and ice are above the water layer.

Activity Corner C (P.144) 1(b) These substances are floating on water because they are _____________ than water. less dense

Activity Corner C (P.144) 2(a) Ice, water, iron nail and mercury are below the water layer.

Activity Corner C (P.144) 2(b) These substances sink below oil because they are _____________ than oil. denser

Activity Corner C (P.144) 3. Polystyrene, oil, ice, water, iron nail, mercury.
