            • Introduction - MST4.I.PS3.Introduction:
              Objects in the universe are composed of matter. Matter is anything that takes up space and has mass. Matter is classified as a substance or a mixture of substances. Knowledge of the structure of matter is essential to students' understanding of the living and physical environments. Matter is composed of elements which are made of small particles called atoms. All living and nonliving material is composed of these elements or combinations of these elements.

              • Major Understandings - MST4.I.PS3.1a:
                Substances have characteristic properties. Some of these properties include color, odor, phase at room temperature, density, solubility, heat and electrical conductivity, hardness, and boiling and freezing points.
                Assessments
              • Major Understandings - MST4.I.PS3.1b:
                Solubility can be affected by the nature of the solute and solvent, temperature, and pressure. The rate of solution can be affected by the size of the particles, stirring, temperature, and the amount of solute already dissolved.
                Assessments
              • Major Understandings - MST4.I.PS3.1c:
                The motion of particles helps to explain the phases (states) of matter as well as changes from one phase to another. The phase in which matter exists depends on the attractive forces among its particles.

              • Major Understandings - MST4.I.PS3.1d:
                Gases have neither a determined shape nor a definite volume. Gases assume the shape and volume of a closed container.
                Assessments
              • Major Understandings - MST4.I.PS3.1e:
                A liquid has definite volume, but takes the shape of a container.
                Assessments
              • Major Understandings - MST4.I.PS3.1f:
                A solid has definite shape and volume. Particles resist a change in position.
                Assessments
              • Major Understandings - MST4.I.PS3.1g:
                Characteristic properties can be used to identify different materials, and separate a mixture of substances into its components. For example, iron can be removed from a mixture by means of a magnet. An insoluble substance can be separated from a soluble substance by such processes as filtration, settling, and evaporation.
                Educational Resources Assessments
              • Major Understandings - MST4.I.PS3.1h:
                Density can be described as the amount of matter that is in a given amount of space. If two objects have equal volume, but one has more mass, the one with more mass is denser.
                Educational Resources Assessments
              • Major Understandings - MST4.I.PS3.1i:
                Buoyancy is determined by comparative densities.
                Educational Resources
              • Major Understandings - MST4.I.PS3.2a:
                During a physical change a substance keeps its chemical composition and properties. Examples of physical changes include freezing, melting, condensation, boiling, evaporation, tearing, and crushing.
                Assessments
              • Major Understandings - MST4.I.PS3.2b:
                Mixtures are physical combinations of materials and can be separated by physical means.
                Assessments
              • Major Understandings - MST4.I.PS3.2c:
                During a chemical change, substances react in characteristic ways to form new substances with different physical and chemical properties. Examples of chemical changes include burning of wood, cooking of an egg, rusting of iron, and souring of milk.
                Assessments
              • Major Understandings - MST4.I.PS3.2d:
                Substances are often placed in categories if they react in similar ways. Examples include metals, nonmetals, and noble gases.
                Assessments
              • Major Understandings - MST4.I.PS3.2e:
                The Law of Conservation of Mass states that during an ordinary chemical reaction matter cannot be created or destroyed. In chemical reactions, the total mass of the reactants equals the total mass of the products.
                Assessments
              • Major Understandings - MST4.I.PS3.3a:
                All matter is made up of atoms. Atoms are far too small to see with a light microscope.
                Assessments
              • Major Understandings - MST4.I.PS3.3b:
                Atoms and molecules are perpetually in motion. The greater the temperature, the greater the motion.
                Educational Resources Assessments
              • Major Understandings - MST4.I.PS3.3c:
                Atoms may join together in well-defined molecules or may be arranged in regular geometric patterns.
                Assessments
              • Major Understandings - MST4.I.PS3.3d:
                Interactions among atoms and/or molecules result in chemical reactions.
                Educational Resources
              • Major Understandings - MST4.I.PS3.3e:
                The atoms of any one element are different from the atoms of other elements.
              • Major Understandings - MST4.I.PS3.3f:
                There are more than 100 elements. Elements combine in a multitude of ways to produce compounds that account for all living and nonliving substances. Few elements are found in their pure form.
                Educational Resources Assessments
              • Major Understandings - MST4.I.PS3.3g:
                The periodic table is one useful model for classifying elements. The periodic table can be used to predict properties of elements (metals, nonmetals, noble gases).
