This document provides an introduction to the properties of matter and different states of matter. It includes objectives about identifying phases and properties of matter, describing mixtures, and determining properties based on given situations. It also explains how temperature affects the motion of atoms. Several activities are described to help students classify states of matter, observe how temperature affects particle movement, distinguish physical and chemical properties, and classify changes as physical or chemical.

Objectives: Identify the different phases and properties of matter
Describe the characteristic properties of a mixture
Determine the properties of matter based on the given situation
Explain how temperature affects the motion of atoms
Matter is anything that occupies space and has mass. Matter may be either be living or non-living, has an
odor or no odor. It can be detected using our senses-sight, hearing, taste, touch, and smell. Matter is what the world
is made of. The materials surrounding us, the air we breathe, the earth beneath our feet, the food we eat, the water
we drink, and even the stars of the universe are forms of matter. Each substance has characteristics set of
properties that help identify it among other substances. These properties can be classified as physical or chemical
and extensive or intensive properties.
Activity 1: The following are the descriptions/examples of the different states of matter, classify them as to
what state of matter it describes. Write after the sentence if it is SOLID, LIQUID, GAS, or PLASMA.
a. Particles are slightly close.
b. Have definite shape and volume.
c. Takes the shape of the container.
d. Has no definite shape but has definite volume.
e. Particles are easily compressed into smaller volume when pressure is increased.
f. Particles vibrate in fixed position.
g. neither have a definite volume nor a definite shape.
h. Has the ability to expand to fill any volume.
i. Particles cannot move around.
j. Particle are farther apart.
k. Particles are tightly packed together.
l. Are made up of groups of negatively and positively charged particles.
m. Particle are not arranged in a rigid or orderly manner.
n. Often observed as ionized gas, aurora borealis, lightning and comet tails.
o. Has no definite volume.

2. GENERAL CHEMISTRY1 MODULE- FERLYNSISESTRADA 2
Activity 2
Materials needed: 2 clear glasses, food coloring (liquid or powder) or orange juice, hot water and cold water
Procedure: Pour hot water on one glass and cold water on the other glass. Put a food coloring into each glass. Do
not stir the mixture! Observe what happen
You can also visit this website for better understanding: https://phet.colorado.edu/en/simulation/legacy/states-of-
matter. Click the phase of matter that you want to test under change state then adjust the temperature (heat and
cool). Observe what happens.
Process questions:
1. In which glass of water did the food coloring spread the fastest? Why?

Activity 3: Perform or analyse the different learning activity below. Then answer the following questions.
Learning Activity 1: Measure the length and width of the two pieces of wood (available at home)
Learning Activity 2: Tear a paper into four pieces. Burn a piece using the match. Set the burning material on the
aluminum pan. Observe what happens to the match and the paper.
Learning Activity 3: Mix salt and water. Stir until all salts are dissolved.
Process Questions:
1. What are your general observations about the activity?
