Your goal is to use what you know about the physical properties of matter, proportional relationships, and patterns to design and carry out an investigation that will enable you to collect the data you need to determine the identity of the unknown substances.
Physical properties are those that can be determined or measured without changing the composition or identity of the substance. These properties include color, odor, taste, density, melting point, boiling point, conductivity, and hardness. Chemical properties tell us how a substance interacts with other substances. Such properties include ...
Matter can be classified in different ways using physical and chemical properties. Physical properties include color, odor, density, hardness, structure, solubility, melting point, and boiling point to name a few.
Students investigate the physical properties of a set of elements. They investigate physical properties including appearance, malleability, density, and solubility in water at room temperature. They are introduced to the concept that each element is composed of a specific type of atom. MATERIALS AND ADVANCE PREPARATION For the teacher
Explore how the physical properties of matter can help us identify mystery matter like powders and metals. Follow the 5E Model, incorporating CER, hands-on activities, reading, science notebooks, investigation worksheets, vocabulary, a quiz, and an open-response prompt. Example photos, teacher directions, and answer keys are provided.
Describe matter based on its physical and chemical properties. Prove understanding of the difference between physical and chemical properties by sorting matter. Before you begin: read of the information/directions on the left side of the screen. Then answer these pre-lab questions.
Identify observable evidence of a physical change (e.g., change in shape, size, phase). Identify observable evidence of a chemical change (e.g., color change, heat or light given off, change in odor, gas given off).
