There are many misconceptions about the chemistry concept, â€œConservation of Massâ€. Thus, the aim of this video lesson is to teach students about the chemical concept of Conservation of Mass through several chemistry experiments. The students will carry out experiments while assisting a fortune teller named Pak Belalang to gain victory for his kingdom. In an effort to help Pak Belalang, students should be able to answer all the questions related to the Conservation of Mass that are posed by an evil witch. In this video, materials such as a box of matches, a closed and open container, a box of panadol soluble tablets (Alka-Seltzer), and weighing scales are needed. At the end of the lesson, students will be able to see that mass is â€œconservedâ€. The lesson will take up to 60 minutes to complete.
