Prepared by : Mrs. Shirley P. ValeraSY 201-2015St. Augustine / St. Francis

Objectives

• Identify the characteristics of matter in terms of their properties.

• Conclude that matter occupies space and has weight.

Fast sharing

matter

Discussion on their responses in the fast sharing activity.

Choose one object and describe all the properties that they can observe about the object.

Collaborative activity:Activity 5.1 : Properties of Matter I.Problem : What are the properties of matter?

II. What You need:

platform balance block of wooddrinking glass

Pencil stone marker

Book water a pail with water

Deflated balloon paper clips

Collaborative activity:Activity 5.1 : Properties of Matter

III. What to do: Part A. 1. Prepare the platform balance. 2. Get the mass of the book, block of wood, pencil, and stone separately. Get also the mass of water in the glass and the mass of air inside the inflated balloon ( with the teachers guidance ). 3. Record their mass.

III. What to do: Part B. 1. Half-fill a glass with water. Use the marker to mark the level of water. 2. Drop the stone in the glass.

Part C. 1. Invert an empty glass and dip it into the pail of water. Do not tilt the glass. 2. Take the glass of the water while keeping it upside down.

IV. What have you formed out? 1. What is the mass of the:

a. book - d. stone – b. pencil - e. water in glass-

c. block of wood - f. air inside the balloon- 2. What happened to the level of the water when you dropped the stones.

Discussion on the result of the activity

The book , wood, pencil, stone , air and water have mass. The rising of the level of water in the glass shows that matter occupies space. When glass is inverted and dipped into the pail of water , water did not enter the glass because the trapped air inside the glass prevented the water from entering.

The activity shows two important properties of matter.

1. Matter has mass

2. Matter occupies space. It has a volume.

Self-exploration:Mass – is the pull of gravity on

matter. Ex. Dropping an object, it will fall

to the floor because of the earth’s gravity that pull all objects toward it.

Weighing an object is measuring the pull of gravity. Gravity controls the weight of an object.

Getting closer to the center of the earth, the pull of gravity gets stronger, weigh is more.

Moving away from the center of the earth, the pull of gravity gets weaker , weigh is less.

Weigh is slightly less on top of a high mountain than in plain.

Gravity is a force that pulls all objects toward the center of the earth.

• Weight is sometimes interchanged with the word mass because they are related. The mass of an object is reflected by its weight. The more mass an object has, the greater its weight is.

• Mass refers to the amount of matter an object contains. It is not affected by gravity.

The pull of gravity on Earth , Moon, and Jupiter are different from each other because they are not the same size. Therefore , te weight of an object will be different in Earth, Moon, and Jupiter, but the mass of the same object will not change.

b. Write what you learn from the reading in a three column chart.

Mass Weight Volume

Discussion on their answers to the following questions:

a. How does matter become beneficial to our daily life?

b. Why is it important to understand the properties of matter?

Discussion on their answers to the following questions:

6. Let the children read the paragraph about “Density”(Science and environment) on page 219 of the

• Let the pupils compose a song (or video: song of matter)

Generalization

Matter is anything that occupies space and has weight.

Valuing

appreciation on how matter are beneficial to our life

EvaluationA. What is the difference between weight and

mass?

B. How do you measure the volume of regular solids?

C. How do you measure the volume of irregular solids?
