Video 1: Kid’s misconceptions on volume of water in 2 containers.
Prior to present the video of “how to measure the volume of liquid”, an interesting video on kids misconception on volume with respect to container’s height was shown below. This preliminary video showed how a child student make his common mistake to judge the same volume of liquid in two different size of container (with different height). After conversation guidance and hand-on demonstration given by the Teacher, the student finally managed to understand the concept of liquid volume.
Video 2: How to Measure The Volume of Liquid Using Graduated Cylinder
In this video, the teacher is showing small, medium and large graduated cylinder that use to measure the different volume of liquid from irregular shape of container (of unknown volume). The teacher explained the correct method of measurement such as placing the cylinder on the flat surface and how to read the scale of the cylinder to avoid parallax error on the curve line. At the end, the teacher showed how to transfer the water from a beaker to the graduated cylinder and read the scale of the cylinder. In this video, the teacher has delivered very effective lecture to the student on how to adopt right measuring tool and methodology to measure a unknown liquid volume in a scientific way.
