Physical changes are those in which the shape, size, or state of the matter changes, but the substance is still essentially the same. Matter can exist as a solid, liquid, or gas (or plasma) and can change in many ways. Air, water, rocks, trees, stars, and animals all consist of matter. Everything that has mass and volume, no matter how small, is made of matter. Emphasize whether a new substance is or is not created by the formation of a new substance with different properties. Standard 5.2.3 Plan and carry out investigations to determine the effect of combining two or more substances. Emphasize making observations of changes supported by a particle model of matter. Standard 5.2.1 Develop and use a model to describe that matter is made of particles on a scale that is too small to be seen. Whether a change results in a new substance or not, the total amount of matter is always conserved. When two or more different substances are combined a new substance with different properties may be formed. ![]() Substances have specific properties by which they can be identified. Matter is made of particles that are too small to be seen but still exist and can be detected by other means. Strand 5.2: PROPERTIES AND CHANGES OF MATTER All substances are composed of matter.
