Teaching Students About Density Divided by Mass


Density divided by mass is an important concept for students to understand in physics, chemistry, and engineering. This concept can be difficult for some students to grasp, but with effective teaching strategies, educators can help make it more accessible. In this article, we will explore various methods and tips that instructors can implement in order to teach students about density divided by mass effectively.

Start with the basics

Before diving into density divided by mass, ensure that students have a thorough understanding of basic units and dimensions such as length, mass, and volume. Familiarity with these units is critical in comprehending the concept of density. Begin by explaining the formula for density (density = mass/volume) using examples drawn from real-life scenarios to promote relatability.

Use relatable examples

One approach to teaching density divided by mass is through practical and engaging examples that students can relate to in their daily lives. For instance, compare different liquids’ densities by having students observe oil floating on water, or use materials like cork and metals to demonstrate the differences between dense and light objects.

Hands-on activities

Hands-on activities are an effective approach to deepen learning experiences. One such activity could involve measuring the mass and volume of various objects provided in the classroom, then calculating their densities followed by ranking them from highest to lowest densities. This allows the student not only to calculate density but also develop an understanding of how density is relatively distributed among different materials.

Visual representation

Utilizing visual aids such as diagrams or graphs can help facilitate better comprehension in some students. For example, use a graphic illustrating how the relationship between mass and volume affects density: as volume increases keeping the mass constant, density decreases; similarly, when mass decreases at a fixed volume, density decreases as well.

Address misconceptions

Many students often struggle with the concept of mass and may mistakenly be under the impression that heavier objects are always denser. Be sure to thoroughly address these misconceptions so that proper understanding of the density-to-mass relationship can be established. This can be achieved through extensive examples in which various scenarios are compared.

Real-world applications

Discussing real-world applications of density divided by mass can promote deeper comprehension. Students will appreciate the relevance when they’re shown instances where this concept is applied, such as determining an object’s buoyancy or choosing appropriate construction materials for a specific project.


Teaching students about density divided by mass can indeed be a challenging task. However, by employing varying teaching strategies and incorporating hands-on activities, relatable examples, as well as addressing misconceptions, educators can make this concept more accessible to students. With a solid understanding of density divided by mass, students will possess a key fundamental skill in science and engineering fields.
