Obtain reliable and valid quantitative data through careful and skilled use of measuring instruments, e.g. balances, graduated cylinders, computer probes Distinguish between qualitative and quantitative properties based upon observations of a substance Experiment to determine specific properties of substances that are useful in identification of the substance such as density, acidity, corrosiveness, strength, stretchability, melting point, or solubility Use derived measurements of objects or substances to determine non-observable properties, e.g. density Describe, compare, and classify elements, compounds, and mixtures 5b Curriculum Standard: Students will demonstrate an increasing ability to understand that matter is composed of dynamic interactive units or particles and that all the properties and changes in matter can be explained in terms of the forces involved in the interactions of these units.
