• Is there is an underground lake in the model?
• Where is the water?
• What is needed to maintain the supply of water?
• Could the well be pumped dry?
• Are wells used to supply water in all countries or just some countries?
The activity is simple enough to be understood by children of all ages, and can be used in any lesson, e.g. in science or geography where water supply is being taught, or where renewable and non-renewable resources are featured.
This is one of many 'watery activities' stored on our website. For a complete list, refer to 'Teaching strategies'.

This is a great demo! Perhaps you could explore pollution issues if you "contaminate" the water with food colouring and test how long it takes to arrive in the drinking water, and how long it takes to flush out again. Cheers!
Thank you, Julian, for your enthusiastic comment, which is of vital significance in many parts of the world. It has reminded us that we have already produced a simple activity to demonstrate the rate at which pollutants seep into groundwater supplies, using a plastic box full of sand, some plastic cups and a colouring agent for the water. See www.earthlearningidea.com "From rain to spring: water from the ground - Demonstrating how water flows through the ground – and how it can be used and polluted".
