Properties of Matter: Physical Sciences
1.0 Differentiate between weight and mass, recognizing that weight is the amount of graviational pull on an object.
2.0 Differeniate between volume and mass. Define density.
3.0 Recognize that the measurement of volume and mass requires understanding of the sensitivity of measurement tools (e.g., rulers, graduated cylinders, balances) and knowledge and appropriate use of significant digits.
4.0 Explain and gice examples of how mass is conserved in a closed system.
Mass and Weight
Mass is a measurement of the amount of matter something contains, while weight is the measurement of the pull of gravity on an object. The Mass of an object doesn't change when an object's location changes. Weight, on the otherhand does change with location.
Mass Volume Density
Volume is the amount of space an object occupies. The volume of an object can be calculated using mathematical equations. The volume of a cube can be found using the formula V=lxwxh. Density= Mass/Volume. Density is expressed in grams/cubic centimeter (g/cm3).
Scientific Notation Study Link
The Law of Conservation of Matter states that matter cannot be created or destroyed in a chemical reaction.
The mass of the reactants is equal to the mass of the products in a closed system.
