The Meaning of Volume of Liquid
Volume of liquid refers to the capacity of liquids in the containers. Normally volume of liquid can be measured using non standard units and in standard units which is called millimeters (ml) and litters (l) in the metric system. Investigations amount of liquids which can be poured between containers of different shapes and sizes. Exploration of capacity or volume of liquid involves manipulation of containers of various sizes that may either be collected or purchased for classroom activities. A cheap way to do the activities is to have your students collect some containers such as mineral water bottles, soft drink cans, vases and many more which can be found around them.
The above chart is made by a cheap and possible to be created item. Teacher will make a mental switch to metric by pouring, measuring and creating a handy chart to compare volumes.
Teacher can create this handy chart by finding a one liter bottle, such as a water of bottle. Then wash it to make sure it’s clean to be use and dry it under the sun. Teacher can asks the pupils to gather five to six different measuring tools such as cups and container with printed volume amounts. After that, fill the container with water. When everything is ready, teacher may ask the pupils question like, how many of each of them do you think will need to fill the little bottle? So the pupils will start estimating.
Teacher will pours each container at a time. Then mark the water levels using a line of marker on the bottle to show the water level for each container. Remember to choose a different colour for each measurement. Keep continue the process until you have achieve one liter. Then compare the finding to your estimates. After that, empty the bottle before experimenting with another measuring tool.
Then the last process is to use a cardboard as tall as the liter bottle and about twice as wide to lay behind the bottle. Extend the line from the bottle on the cardboard using the same colour. After that label the line and glue the bottle to the cardboard.
