Lesson 2: Matter at Home and in SchoolHow Do You Describe Matter Around You?

-According to Its Mass and Volume

Lesson 2: How Do You Describe Matter Around You:

According to Volume

Review:

Get any solid food package in your home and share the information about its weight.

Remember:Mass and weight of solid materials are measured in grams or kilograms.

Activity:

a. Get 2 pieces of plastic or cellophane.b. Blow air on the 1st plastic as I count to 15.c. Blow air on the 2nd plastic as I count to 5.

Are your plastics filled with air?Air is in form of gas.Air has no specific shape. It takes the shape of its container, like the plastic bag.Is air a matter?

Which plastic bag has more mass? Plastic 1 or 2?

Remember:Gas also has mass that can be measured in g or kg. Gas has no specific shape but only takes the shape of its container.

Think about this!Mia will bake a cake. She will be mixing flour, milk, water eggs and butter.

Which tool will she use to measure the following:-flour-milk-water

Let’s find out!

Are water, milk and oil matter?What kind of matter are they, solid, gas or liquid?

Do the materials in each object occupy space?

Do we put them in containers like bottles, cans or packs?

Today we will focus on how to measure the amount of liquid in an object.

The amount of matter the object contains is called MASS.

Do Activity on page 15

Which amount of matter has greater mass? ½ cup or 1 cup of water?

Do Activity on page 15

Which occupies more space? ½ cup or 1 cup of water?

Next, we will learn on how to measure the space the liquid occupies.

The space occupied by the matter is called VOLUME.

Let’s watch how we measure the VOLUME of liquids using the measuring instrument, measuring

cup:

Let’s watch this video.

Examine a measuring cup and the lines marked with numbers.

A measuring cup is used to measure the space occupied by matter---called the VOLUME OF THE MATTER.

Liquids can be measured in:ml as in milliliter or cu as in cup.

1000 ml is equal to 1 liter (1L)

ACTIVITY FOR LIQUIDTeacher will show how LIQUIDS are measured by milliliter (ml) and will show an amount of 1 L material.

Watch this.

MASS and VOLUME OF LIQUIDS

The amount of matter or liquid is called mass. It can be measured in g or kg. While the space occupied by the matter is called VOLUME. Volume is measured in milliliter (ml) or liter (L)

Do Exercise A on page 18. We shall check next meeting.Choose the correct measuring instrument to describe the matter.

account.Due date of Submission is on Oct 26.

With your parents’ assistance, look for the different liquids available at home. Observe the package (in bottle, in can, or package). Identify the amount of liquid according to their label.Record the measurement in the table below.Remember:Milliliter or mL is the unit for measuring the space occupied by matter (or volume).Some labels may have the volume measured in litter with symbol L. You need 1000 mL to equal 1L.
