For children in Grade 5 learning about space systems and Earth.

From the Curriculum:

Making greater use of renewable and alternative sources and conserving energy are options that students need to know about if we are to sustain our present standard of living and ensure adequate energy supplies for future generations. Students must also recognize that there are immediate and long-term impacts and costs associated with every choice.

Big Ideas:

• Energy sources are either renewable or non-renewable.
• Energy can neither be created nor destroyed, but it can be transformed.
• Choices about using energy and resources have both immediate and long-term impacts.
• Conservation (reducing our use of energy and resources) is one way of reducing the impacts of using energy and resources.
