Product Description
Award-winning video and lesson investigations on the topic of water use. Key concepts include:
- Huge amounts of water are needed to supply cities and towns.
- Sometimes artificial lakes (reservoirs) have to be created.
- Dams are needed to keep the water in the reservoir.
- Building a reservoir changes the use of the land.
- Reservoirs provide a centralised water source for a community.
- They are created in river valleys, existing lakes, or spring fed ponds.
- The ground area is dug out and deepened to adjust to the increased water level.
- For some, the building of a reservoir is a disadvantage, eg they lose homes and/or land; for others, it can be an advantage, eg for water recreation
