Let's watch a movie!

Ok,now Let's play a game

This term in Social Studies we will be looking at water, the choices society makes regarding water, the reasons for these choices and the impacts these choices can make.

We will begin by looking at dams.

Dams have three main purposes, to act as reservoirs (storage and purification of water), to create power (hydroelectric) and to act as a flood barrier if heavy rainfall causes sudden surges of water.

In Auckland, 'Watercare' manage a number of dams and reservoirs in the Waitakere and Hunua Ranges. 

Click here to find out more about them.  If you want to see what they look like, copy and paste the name of a reservoir into youtube or google images.

Find out:
1) The biggest dam/ reservoir in Auckland (in terms of lake capacity)
2) The smallest dam/ reservoir in Auckland (in terms of capacity)
3) The newest dam in Auckland
4) The oldest dam in Auckland

So, dams are good things...right?
Take a look at this
Why do you think they are so please to release all the water they have worked so hard to store up?

Flooded Habitats, culture and homes                 Greenhouse Gas Emissions 
Displaced People            Hydropower for electricity           Maintenance or Decommissioning
Loss of livelihood from fisheries              Food from irrigation
Salinity, waterlogging                Riverbank erosion                 Loss of downstream aquifers
Environmental flow requirements         

There are lots of labels on this picture that give you an idea for some of the benefits and drawbacks of building a dam.
In your social studies book, categorise these labels into 'Benefits', 'Drawbacks' 'Neither', 'Both'.  You should use a Venn diagram to do this.  You will need to discuss some of the terms and/ or research the meaning of some of these words in order to complete the activity.
