Measuring Volume Of Liquid : Teaching Aids



Teaching and learning process would be more meaningful if we can associate it with our daily life. Students are able to understand better with something that they used to see everyday. Moreover, they can remember it better because they really understand why they have to learn the lesson.
There are two sets of teaching aids suggested here. The first set of teaching aid would include the packaging of fresh milk that we can get from any supermarket. Fresh milks come in different packaging. Some of them are in bottles and others are in packets. For young children they like to drink milk and these are something that they are familiar with. The packaging comes in different sizes as well. Teacher will have to prepare the containers of fresh milk before entering the class. The preparation of these teaching aids does not need any extra budget as most of us drink milk and we just have to collect the containers and clean them properly before giving to students. 

The second teaching aid would be the different sizes of beakers that we have in school labs. These beakers are properly calibrated. It is a good instrument to introduce students to the concept of volume of liquids. It is easier for students to understand when we use instrument with the same shape but different in size. They have no problem in relating the size of the object and its capacity to hold liquid. However, they might have the wrong perception that the higher the liquid in the container means the higher the volume of the liquid in the container. This is the misconception that teacher needs to show the students.
