Teaching Students About Biomolecules

Biomolecules are the building blocks of life. They are the compounds that make up all living things, including plants, animals, and humans. Understanding biomolecules is critical for students in fields such as biochemistry, biology, and genetics. But even students who are not pursuing careers in science can benefit from learning about biomolecules. Here are some tips for teaching students about biomolecules.

Start with the Basics

Before diving into the different types of biomolecules, it’s important to teach students the basics of chemistry. This may include an overview of elements, atoms, and molecules. Once the foundation is in place, students can begin to understand how biomolecules are made up of atoms and how they relate to the chemical structures they already know.

Explain the Different Types

There are four main types of biomolecules: carbohydrates, lipids, proteins, and nucleic acids. Each of these biomolecules plays a unique role in the body. Carbohydrates provide energy, lipids make up cell membranes, proteins are involved in cell structure and function, and nucleic acids (DNA and RNA) are responsible for genetic traits. It’s important to explain how these biomolecules function in the human body and how they are used in various processes.

Relate to Real Life

One of the best ways to teach about biomolecules is by relating their functions to everyday life. For example, when discussing carbohydrates, use examples such as bread, pasta, and cereals. Explain how they are broken down into glucose and how the body uses glucose as an energy source. For proteins, use examples such as eggs, meat, and beans. Explain how proteins are involved in muscle development and repair. This way, students can see the importance of biomolecules in their daily lives.

Activities and Experiments

To keep students engaged, it’s a good idea to incorporate hands-on activities and experiments. For example, have students build models of the different biomolecules using materials such as colored pipe cleaners, beads, or even candy. This gives students a visual representation of what they’re learning and helps them remember the information better. There are also numerous lab experiments available online that can help students better understand how biomolecules function in the body.


Teaching students about biomolecules is critical in helping them understand the fundamental building blocks of life. By using relatable examples, hands-on activities, and experiments, students can better grasp how biomolecules function in the body. As educators, it’s important to help students see that science is not just a subject in school, but something that is applicable in everyday life.
