The discovery of atoms was a major breakthrough in the field of chemistry. After several studies, it was constituted that all chemical combinations are governed by two major laws: law of conservation of mass and law of constant proportions. In this video, students will get to know about the law of conservation of mass, which was developed by Antoine Lavoisier. According to this law, mass can neither be created nor destroyed in a chemical reaction. This means that new substances are formed only when previously existing substances combine in nature.
This video satisfies the 5-PS1-2 requirement of fifth-grade science proficiency.
Students who demonstrate understanding can: 5-PS1-2. Measure and graph quantities to provide evidence that regardless of the type of change that occurs when heating, cooling, or mixing substances, the total weight of matter is conserved.
