Be able to define matter (i.e. anything that has mass & volume). Be able to provide examples of matter and non-matter. Be able to explain how matter is classified (i.e. pure substances cannot be physically separated but mixtures can). Be able to classify matter into pure substance (element or compound) and mixtures (homogeneous/solutions and heterogeneous/mechanical mixtures). Be able to explain the six principles of particle theory. Be able to describe how solids, liquids & gases differ in the spaces between particles & movement. Be able to describe a scenario using particle theory (i.e. explain why perfume fills the room once it is sprayed). Be able to explain the difference between physical & chemical properties. Be able to identify & describe objects using physical & chemical properties. Be able to explain the difference between physical & chemical changes. Be able to identify scenarios as physical or chemical changes with appropriate reasoning.
Understand the Problem
The image contains a list of learning objectives related to matter, particle theory, and physical and chemical properties and changes. It outlines specific topics for students to understand and explain.
Answer
Matter is anything with mass and volume. It includes solids, liquids, and gases. Matters can be classified into pure substances and mixtures. Particle theory explains behavior in states of matter. Physical properties observe without change, chemical properties involve interactions.
To define matter: it is anything with mass and volume. Examples of matter include solids, liquids, and gases; non-matter includes light and sound. Matter can be classified into pure substances (elements or compounds) and mixtures (homogeneous and heterogeneous). The six principles of particle theory describe the behavior of particles in different states. Solids have tightly packed particles, liquids have closely packed particles that move freely, and gases have widely spaced particles. Perfume fills a room because gas particles move freely and spread to fill the available space. Physical properties can be observed without changing the substance, while chemical properties describe how substances interact. Physical changes affect form, whereas chemical changes result in new substances.

More Information
Matter makes up the physical universe, and its classification helps in understanding and processing materials in practical and scientific applications.
Tips
A common mistake is confusing mixtures with compounds; remember, compounds are chemically combined, mixtures are physically combined.
