This engaging Grade 4-5 science passage explains biomass energy and how it works as a renewable energy source. Students learn how biomass energy comes from burning plant materials, wood, and organic waste to release stored energy originally captured from the Sun through photosynthesis. The passage connects to real-world examples like burning wood for heat and using crop waste to generate electricity. Aligned with NGSS 4-ESS3-1 standards, this comprehensive resource includes the main reading passage, a simplified differentiated version, Spanish translations of both versions, an interactive glossary, multiple-choice quiz questions testing recall and comprehension, writing activities with suggested answers, and graphic organizers. All content is audio-integrated to support diverse learners. Students explore why biomass is considered renewable because new plants can grow quickly to replace what was burned, making it a sustainable energy option. The material uses age-appropriate language and concrete examples to help elementary students understand this important renewable energy concept.

People have used biomass energy for thousands of years. When you see someone burning wood in a fireplace or campfire, that's biomass energy at work. Image credit Pixabay.
Biomass energy is energy that comes from living things or things that were recently alive. This includes plants like trees, corn, and grasses, as well as organic materials like wood, food scraps, and animal waste. Organic materials are things that come from plants or animals. People use biomass to create energy that powers homes, schools, and factories.
When biomass is burned or processed in special machines, it releases energy in the form of heat and electricity. For example, burning wood in a fireplace releases heat energy that warms a room. Large power plants can burn wood chips or plant materials to make electricity for entire communities. Some farms collect animal waste and food scraps, then use special equipment to turn them into a gas called biogas that can be burned for energy.
Biomass is a renewable energy source, which means we can replace it. Renewable energy sources do not run out because we can make more of them. Unlike coal or oil, which take millions of years to form underground, we can grow new trees and crops in just months or years. When we plant new trees to replace the ones we use for energy, we ensure there will always be more biomass available.
Using biomass energy helps reduce waste because we can use materials that might otherwise be thrown away, like food scraps or sawdust from lumber mills. This makes biomass an important part of finding cleaner ways to meet our energy needs.
