Do you agree with the statement? Elements make up matter. Yes No

Do you agree with the statement? The mass of an object changes when it ha been moved. YES NO

Do you agree with the statement? Density is an example of a chemical property of an object. YES NO

Do you agree with the statement? An object will float if its density is less than the liquid’s density. YES NO

Elements Elements are basic kinds of matter and few elements are in pure form like gold. Chemical properties of elements tell how a material changes into other materials, which include burning, rusting and photosynthesis. Physical properties tell an object’s color, smell, density, texture hardness and can include shiny, bendable and conducts heat.

Mass, Weight & Volume Weight is a measure of the pull of gravity on an object. Mass is the amount of matter in an object; the amount of mass in an object affects the weight but mass doesn’t change with gravity. You use a balance to measure the mass of an object. Volume is the amount of space that an object takes up.

Properties of Objects & Materials The properties of objects include shape, size and mass; which can change if you do something to it. The properties of materials include density, hardness and attraction to magnets; no matter what you do to the material its properties will stay the same. A gold ring and gold necklace have the dame density. As gold is melted it has the same mass.

Density & Buoyancy Density is a measure of the amount of matter in an object and is a physical property of a substance. Density is the same no matter how much of the object is measured using tools like scales to measure the mass and rulers for volume. Find density by dividing mass and volume. Buoyancy is the ability of an object to float or sink in a liquid. An object that has more density than the liquid will sink, and an object less dense than the liquid will float. Different liquids can have different a density and settle in layers. BRAIN POP: Measuring Matter, Buoyancy
