If you are teaching about water reservoirs and distribution, check out this activity! Do your students struggle to grasp how little freshwater we have on Earth? Creating a visual model is much more powerful than showing them a pie chart! In this lab, students will create a model to scale of where Earth's water is located.

There are 3 versions included in this lab:

1. In version 1 (grades 6-7) students are given all the measurements and simply have to pour them into the proper containers. No calculations necessary.

2. In version 2 (grades 7-9) students are walked through the process of how to calculate the water quantities.

3. In version 3 (grades 9-11) students are given the percentages and materials and have to figure out how to create a scaled model on their own.

to see state-specific standards (only available in the US).
Develop a model to describe the cycling of water through Earth’s systems driven by energy from the sun and the force of gravity. Emphasis is on the ways water changes its state as it moves through the multiple pathways of the hydrologic cycle. Examples of models can be conceptual or physical. A quantitative understanding of the latent heats of vaporization and fusion is not assessed.
