Energy sources and their environmental impacts come into focus in this Grade 4 Science reading organizer. Students explore how sunlight, wind, moving water, fossil fuels, and heat from inside Earth can be used as energy sources, while practising how to identify a main idea and support it with details from an informational passage.

Five Sources, Five Reading Topics

The readings introduce different ways people obtain energy. In “Power from Sunlight,” students explore solar energy. “Wind Makes Electricity” focuses on using wind to generate electricity, while “Energy from Moving Water” introduces hydropower. The passage “Power from Fossil Fuels” examines energy from fuels such as those taken from the Earth. Finally, “Energy from Earth’s Heat” introduces geothermal energy.

Together, these topics give students a foundation for comparing energy sources and considering their environmental impacts. Rather than treating energy as one broad subject, the passages focus on distinct sources and the ways each can be used. This makes the set useful when introducing renewable and nonrenewable energy concepts and discussing how energy choices can affect the environment.

Read, Highlight, and Organize

Each informational text is paired with a main idea and supporting details graphic organizer. Students read the passage, identify and highlight its central idea, then find the details that support it. They write the main idea and supporting information in the matching organizer, using evidence from the text rather than relying on unrelated facts.

This activity provides practice with informational text comprehension, identifying central ideas, selecting relevant supporting details, and summarising science content. The topic-specific reading also introduces vocabulary and examples connected to solar, wind, hydropower, fossil fuel, and geothermal energy.

What Teachers Receive

• Five informational reading passages, each focused on a different energy source
• A matching main idea and supporting details organizer for each reading
• Picture planning spaces connected to the subject of each passage

Classroom Use

Use the set during a Grade 4 unit on energy resources and environmental effects, as teacher-guided reading, or for independent science literacy practice. Passages can also provide starting points for class conversations comparing different ways to generate energy and considering why communities make different energy choices.

By combining specific energy topics with a consistent reading task, this resource gives students a meaningful reason to return to the text: they must find the main idea and choose details that genuinely support it.
