Topic: Properties of Matter
OBJECTIVES
At the end of the lesson, students will be able to:
A. Define the various properties of matter (physical and chemical).
B. Differentiate between intensive and extensive properties of matter.
C. Observe and classify materials based on their physical and chemical properties.
LEARNING COMPETENCY
Students will understand and apply the concepts of the properties of matter by analyzing different materials and identifying their specific properties through observation and classification.
PERFORMANCE STANDARDS
- Define key properties of matter, including physical properties (like color, shape, mass, and volume) and chemical properties (like reactivity and flammability).
- Differentiate between intensive properties (which do not depend on the amount of matter, such as density and boiling point) and extensive properties (which do depend on the amount of matter, such as mass and volume).
- Perform experiments to observe physical changes and chemical changes in materials, and classify them based on their properties.
SUBJECT MATTER: Properties of Matter
-
Definition of Matter
- What is Matter?
- States of Matter: Solid, Liquid, Gas
-
Physical Properties
- Intensive Properties: Color, Odor, Density, Melting Point, Boiling Point
- Extensive Properties: Mass, Volume, Length
-
Chemical Properties
- Reactivity with Other Substances
- Flammability
- pH
-
Observations in Experiments
- Physical Changes vs. Chemical Changes
- Conducting simple experiments to demonstrate different properties of matter (e.g., melting ice, mixing vinegar and baking soda).
-
Classification of Matter
- Elements, Compounds, and Mixtures
- Methods of separation (filtration, distillation, chromatography)
This structure provides clear goals for the lesson and sets the stage for effective teaching and learning about the properties of matter.
