LET'S TRY TO ANSWER

LESSON : VOLUME

1. Which is longer? Circle your choice for each one.

1 liter or 1 gallon 1 liter or 1 quart 1 milliliter or 1 fluid ounce

2. Complete each statement.

1 gallon = _________ liters 1 fl oz = __________ ml 1 quart = _________ liters

3. __________________ is the amount of space an object takes up.

4. The base unit of volume in the metric system in the ___________ and is represented by ___ or ___.

6. Complete each statement.

1 L = ______________ mL 1 mL = ______ cm3 (or cc) = ______ gram*

7. Which is larger? Circle your choice for each one.

A. 1 liter or 1500 milliliters

B. 200 milliliters or 1.2 liters

C. 12 cm3 or 1.2 milliliters*

8. What instrument will we use to find liquid volume? ______________________________________

9. What is the name of the curve you see at the top of a liquid in a cylinder? _____________________

11. What formula do we use to find the volume of regular objects?

Volume = _________________ X _________________ X _________________

ACTIVITY 3 : USING NON-STANDARD UNITS AND STANDARD UNITS

Learning Outcomes:

By the end of the lesson, pupils will be able to measure and compare volume of liquids by using standard units and non-standard units correctly.

Prior Knowledge:

Pupils had learnt how to measure volume of liquid using non-standard units and standard units.

Teaching Aids:

Different sizes of containers, 2 measuring cylinders, a pail of water.

Vocabulary:

more, less, empty, half full, full.

Procedures:

1. Divide the pupils into group of four to do work in their cooperative learning.

2. Appoint one student to be the recorder in the group.

3. Give each group 3 set of containers of different sizes, a pail of water and two measuring cylinders. ( One for milliliter and another one for liter)

4. Each group will fill every container with water and state which is more or less.

5. Then, they will measure the volume of liquid in each container in liter and milliliter by pouring the water from the containers into those measuring cylinders.

6. A group member record the results in the form given:

Conclusion:

For this activity pupils know that volume of liquid can be measured by using non-standard units, but the results just under estimation. By using metric units such milliliters and liter we can find more accurate with the results. On the other hand, pupils also able to understand the relationship between both measurement tools.

Summary:

The learning of volume of liquid begins with concrete experience in realistic situations through measuring using both standard and non-standard units. The capacity of liquid in standard units are measured in millimitres(ml) and litres(l) in the metric system. While in non-standard units they are measured using various containers by stated the capacity wheather more or less. Materials from non-standard units are easier to obtain. It is good to give children experience with unfamiliar systems of measurement .

ACTIVITY 2 : USING STANDARD UNITS

Learning Outcomes;

By the end of the lesson, pupils will be able to measure volume of liquids by using standard units correctly.

Prior Knowledge;

Pupils had learnt that the content of water will be determined based on their containers. The bigger containers show more volume of liquid while the smaller containers give us less volume of liquid.

Teaching Aids;

Different sizes of containers, a pail of water,

Vocabulary;

more, less, empty, half full, full,

Procedures;

1. Divide the pupils into group of four to do work in their cooperative learning.

2. Appoint one student to be the recorder in the group

3. Give each group 5 set of containers of different sizes, a pail of water and two measuring cylinders. ( One
for milliliter and another one for liter)

4. Each group will fill every container with water.

5. They will measure the volume of liquid in each container by pouring the water from the containers into the measuring cylinders.

6. A group member record the results in the form given

*• Introduce the pupils that 1 liter = 1000 milliliter

• 1 liter x 1000 milliliter = 1000 milliliter

Conclusion;

For this activities pupils know that volume of liquid can be measured by using metric units such milliliters and liter. They also understanding the relationship between both measurement tools.

ACTIVITY 1 : USING NON-STANDARD UNITS

Learning Outcomes;

By the end of the lesson, pupils will be able to measure and compare volume of liquids by using non-standard units correctly.

Prior Knowledge;

Pupils had learnt how to compare objects: more or less, many or a few, high or low during their previous lesson while learning A Whole Numbers.

Teaching Aids;

Different sizes of containers, a pail of water,

Vocabulary;

more, less, empty, half full, full,

Procedures;

1. Divide the pupils into group of four to do work in their cooperative learning.

2. Appoint one student to be the recorder in the group

3. Give each group 5 set of containers of different sizes, a pail of water and a small cup as the measurement tool.

4. Each group will record the number of cup needed to fill the water in every containers into the form given.

* Also teach the pupils estimation such as half full, full and empty

Conclusion;

For this activities pupils will bear in mind that the volume of liquid will be determined based on the containers used. The more bigger containers the more quantities of water is needed to fill in.
