INTRODUCTION


Nowadays, pupils did not clear understand about the liquid volume concept. They think the taller container with full water must be much more than the fat container. To ensure students understand the liquid volume concept, effective teaching used to identify what is liquid volume is play a vital role in school.   
    Water is a form of liquid. It is an important natural source and a basic need in our lives. We use water for drinking, washing, cleaning and cooking. Factories producing drinks use water to prepare drinks. How is the amount of water measured?
             Long ago the standard unit of capacity in the English system are the cup, pint, quart, gallon, tablesppon and teaspoon.The name of the traditional volume units are the names of standard containers. Nowaday the standard unit of capacity in the metric system is the litre, millilitre, etc. Measuring cylinders, pipettes, beakers and measuring jugs are some of the tools used to measure the volume of liquid accurately.                                                                                                                                                    
            The volume of anything is the amount of space it occupies.Volume also called as capacity. Capacity and volume can be distinguished; capacity being used for how much a container can hold.
            Pupils should begin their work with volume and capcity by simply experimenting with pouring water into containers to get the basic idea of volume of liquid.  Next , they should also be exposed to the skill of estimating volumes. Formal skills of reading, measuring and recording volume should then follow up.
 Liquid volume is the volume of a given amount of liquid, i.e., the amount of space a liquid takes up. There are a number of different units used to measure liquid volume, but most of them fall under either the metric system of measurement or the Imperial system of measurement.
 This concept is mainly used in measuring volume of liquid. The volume of an item is the amount of space it occupies. Only in case of solids, the amount of space that is occupied by them is decided by their own shapes. The amount of space is not only constant but the shape of the space required by them is always fixed. But liquids and gases have no shape by themselves. They occupy the space available in the containers they are filled. In fact in case of gases, the amount of gas that occupies a container varies with its pressure.
 To ensure understanding from pupils, prepared two different sizes cup and teapots that filled full water. By first impression of students, they can examine which is more water container. By measuring the water, students clearly determined that the liquid volume concept.   
 The designs of teaching methods important to ensure pupils clearly understand the liquid volume concept through experiment. Leading students know the “liquid volume” concept similar with “how much water in the container”. Students understand the concept deeply.
 Teaching litres and mililitres before volume is important because these two units used wisely in routine. Litres and mililitres knowledge teaching by using real life situation. Teaching using real life situation more simple and understanding by students. Besides that, teachers use real life situation able to attract attention from students. Students believed that will use mathematic widely in their future.
When teaching, teacher trying to answer student’s questions, given assumptions, design case scenario, research experiment, analysis data, and examine the conclusion by using real life situation.

CONCLUSION

Teaching Design emphasizes leading students into right ways and experience the teaching process. By guessing how much water inside container, comparison discussions creating measure scale and finally understanding measuring cylinder. Within these activities, students clearly understand the concept. Students learning through liquid volume by compare water in two different containers. Students deeply remember by using experiment.   
However, liquids have no definite shape. They occupy the available space of a container. They spread over the entire the area of section and stands up to a height.  Hence the volume of a liquid is the volume of its container up to the height of the liquid level. For this reason, the volume of hollow shapes is called as ‘capacity’ of the shape.
“Comparing water” is basis knowledge of standard two students. Teaching content divided into two parts: one is comparing how much water in different containers. Through guessing and arguing, students believed that learning how to solve up their problems. Second is comparing how much water is more. Students create their own  tools. In this activity, students learned how to measure water by using measure cylinder.

Students used measurement in their life. Through these activities, students more realized the important of measurement. Experiment leads students understand and remember knowledge of litres and mililitres. They learned liter and milliliter measure by using different methods. Experiment design helps students understand the meaning of litres and mililitres. Students trusted will remember deeply in future.
Teacher learned how to attract attentions from students, how to improve their learning ability, and the important to design a right learning method is very important to teaching learning concepts.
