LIQUID-CAPACITY MEASURE-LITER-MILLILITER.pptx

Grade 3 Lesson for Fourth Quarter.
It is about capacity measure.

1. Capacity of a Container using Milliliter/Liter

2. Drill List the liquids you see at home. How are these liquids packaged?

3. Review Give the most appropriate unit of measure for the following (cm or m). cm cm cm m m

4. Motivation Put two glasses on your table, one glass with water, the other one empty. Pour a small amount of water from one glass to the other. Ask: What is the exact amount of water poured in the empty glass? What units of measure should be used to determine the amount of liquid in the glass?

5. Presenting the Lesson Present real measuring devices that show L and mL: e.g. measuring cup, jug, medicine dropper or beaker Name the measuring devices. Identify what you see on the measuring devices. Ask: What does L stand for? How about mL? What do they measure?

6. Capacity means how much liquid a container can hold. Some of the units of measure for capacity is liter (L) or milliliter (mL).

7. About how many milliliters of water does this glass contain/hold? = Which of these devices will you use? Why?

8. Which of these devices will you use? Why? = Can you put 1 L of water in the small glass? Why? How about in the pail? Why? About how many liters of water can it contain or hold?

9. Performing the Activities Divide the class into 4 groups. Let them do the activities given. Activity – Groups 1 and 2 Materials: measuring cup/jug that shows mL, water, glass, small medicine bottle

10. Procedure: 1. Take turns to use the containers. 2. Fill the container up to its brim with water. 3. Pour the water from the container to the measuring cup/jug. 4. Read the scale carefully. 5. Record the amount of liquid the container holds in the table as shown.

11. Activity – Groups 3 and 4 Materials: plastic cups with labels 250 mL and 100 mL, respectively, 1 L juice drink bottle (see illustration)

12. Procedures: 1. Fill a 250-mL plastic cup with water. 2. Fill the soft drink bottle with 250 ml water until it reaches 1 liter. 3. Record the number of times the 1 L bottle is filled with 250 mL water. How many 250 mL cups of water does the 1 L bottle contain ? How many milliliters of water did you put in the 1 liter bottle? 4. Pour water in a plastic cup up to 100 mL. 5. Fill the bottle with 100 mL water until it reaches 1 liter. 6. Record the number of times the 1 L bottle is filled with 100 mL water. How many 100 mL cups of water does the 1 L bottle contain? How many milliliters of water did you put in the 1 liter bottle? Let the groups present their answers.

13. Processing the Activities How much liquid/water does each of the containers that were given to you hold? How many milliliters are there in 1 liter? How many liter is 1000 ml?

14. Reinforcing the Concept What is the appropriate unit of capacity measure to be used, mL or L for each container.

15. Group Activity How do you measure capacity with metric units? Make a table like the one shown below. Select five empty containers with various capacities. Estimate the capacity of each.

16. Summarizing the Lesson How do we find the capacity using standard unit of measure? When do we use milliliter? Liter? Milliliter (mL) is a metric unit used to measure the capacity of small containers. Liter (L) is used to measure the capacities of the large containers. How do we convert milliliter to liter? To change to liter, divide the amount in milliliter by 1 000. How do we convert liter to milliliter? To change to milliliter, multiply the amount in liter by 1 000.

17. REMEMBER: Capacity means how much liquid container can hold? Milliliter (mL) is a metric unit used to measure the capacity of small containers. Liter (L) is used to measure the capacities of the large containers. To change to liter, divide the amount in milliliter by 1 000. To change to milliliter, multiply the amount in liter by 1 000.

18. ACTIVITY 1: A recipe calls for ½ L of vinegar, 1/4 L of soy sauce and ¾ L of water. How many milliliters will each liquid contain? 2. How many liters of liquid are there in the recipe? milliliters of liquid?

19. Activity 2 Choose inside the parenthesis the correct measurement that will complete the sentence. The can contains (4mL, 4L) of paint. A glass has (250mL, 250L) of milk. The pail has a more or less (10 mL, 10 L) of water. 4) The pitcher has (200mL, 2L) of juice. 5) A cup contains (200mL, 2L) of coffee.

20. Activity 3 Convert the following. 6 L = _____ mL 6. 8 000 mL - _______ L 11 L = ________ mL 7. 2 000 mL = _______ L 3.5 L = _______ mL 8. 4 500 mL = _______ L 10 ¼ L = ______ mL 9. 7 250 mL = _______ L 22 L = _________ mL 10. 15 750 mL = ______ L

21. A. Milliliter (mL) o Liter (L): Which unit of measure is appropriate to use for each item. 1) glue 6) medicine syrup 2) water in a bathtub 7) one cup of red tea 3)orange juice in a punch bowl 8) soup in a bowl 4)shampoo in a sachet 9) gasoline in a container drum 5) tetra pack juice 10) one teaspoon honey EVALUATION:
