To design and build a model water supply system for a human settlement on the Moon.

Key Words

water conservation



"Moon ABCs Fact Sheet"

construction materials
such as cardboard boxes
and tubes, blocks, hoses,
straws, string, pins, rubber
bands, tape, etc.


Think of all the things you do during a regular school day, from the minute you wake up until the time you go to sleep. List each activity which involves water.

Are there any water activities you could eliminate for a day? a week? longer?

What other activities in your town use water? Could any of those activities be eliminated?

During a dry summer, have you ever heard a public announcement that "water conservation measures are in effect"? What activities are affected by this announcement?

Imagine if summer drought continued for years, then how could water be conserved for people? for animals? for crops? for businesses?

Review the "Moon ABCs Fact Sheet." Where is the water on the Moon and in what form or forms does it exist?

Design a water supply system to be used by the Moonbase inhabitants which will rely only on water available from the Moon's resources. You may assume that ample electricity will be available.

Construct a model of this sytem based on your design. It must include the application of at least four facts from the "Moon ABCs Fact Sheet." For example, how will the Moon's gravity affect the design of your system? Maybe your system will be very heavy but still portable by only a few Moonbase workers because the Moon's gravity is only 1/6th of Earth's gravity.

Make a detailed and labeled sketch of the model.
