This activity involves the use of beakers with different size. The activity is very simple and most of the students are able to follow the instructions. First, students will be divided into groups. Then each group will be given four beakers with different size. The beakers will be labeled from 1 to 4 with 1 is the smallest and 4 is the biggest. Then students are instructed to pour 20 ml, 30 ml, 40 ml and 50 ml into each of the beakers accordingly.
Then students are required to observe the height of the water in each of the beakers. Students need to arrange the beakers according to the height. Teacher asks students to point out the beaker with the highest volume of liquid in it. Teacher would like students to observe that beaker with the highest volume of liquid in it does not mean that the liquid must be the highest in the beaker in height.
For high achiever, teacher may ask them to pour the liquid in each beaker to the same height and take the reading of each of the beakers. Students will find out that with the same height of liquid in the beaker, the bigger beaker has the highest volume of water.
