Activity Introduction
NASA is always on the lookout for earth-like planets that we might be able to colonise in the future. 71% of the Earth’s surface is covered in water. That sounds like a lot, but how much can we actually drink? Use your mathematics skills to determine the actual amount of potable water on Earth, so NASA has a clearer idea of what to be looking for.
This is a good activity for kids to complete independently.

[email protected] resources are designed for parents and teachers to use with children in the home environment. They can be used as stand-alone activities or built into existing curriculum-aligned learning programs. Our [email protected] series includes two types of resources. The first are fun and challenging real-world activities for all ages, the second are self-directed lessons for upper primary and secondary students. These lessons support independent learning in remote or school settings.
Cool Australia’s curriculum team continually reviews and refines our resources to be in line with changes to the Australian Curriculum.
