Activity+Cards

=Activity Cards = In the lead-up and during the first part of the game, we will be using the classroom activity cards below. These may be viewed, printed or downloaded as needed.

The activity cards cover 10 topics related to water and the environment and through your investigations you should come to some basic understanding of each. You will be asked to share your work with the rest of the class so make sure it is easily read and is **ALL** your own work.

**Accidents activity card**
 * Spills of many kinds can be villains
 * A spill can occur along distance from the site it affects. Pollutants are carried in the water and may reach the groundwater.
 * Some spills can be difficult or impossible to clean up.

**Flow, silt and sediment activity card** 
 * Dams and other artifical changes (irrigation) to the river change the flow.
 * The flow affects the amount of dissolved oxygen in the water.
 * Flooding can be beneficial to a river system.
 * Soils and silts cause changes to the depth and flow of the water, which in turn affects the temperature and the fishe' ability to breathe.

** Land use activity card ** 
 * Human activity affects water quality.
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Pollutants direvtly emptied into the water system can be generated by factories, sweage, abbattoirs and so on.
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Chemicals and other run-off can enter the water system in indirect ways.
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Cleared land and overgrazed land will allow sediment to wash into waterways.
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Recreation, dams and transport affect water quality

<span style="font-family: Tahoma,Geneva,sans-serif;">** Nutrients activity card ** <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Nutrients from run-off, chemical fertilisers and sewage cause an increase in plant and algae in rivers
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Water temperature is raised, flow is lowered, oxygen is lowered.

<span style="font-family: Tahoma,Geneva,sans-serif;">** Run-off activity card ** <span style="color: #000000; font-family: Verdana,Geneva,sans-serif;">
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Run-off is the rain that is neither absorbed by the ground nor evaporated.
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Run-off can carry with it all the loose materials in the catchment, washing soil, fertilisers and pesticides into the waterways.

<span style="font-family: Tahoma,Geneva,sans-serif;">** Salinty activity card ** <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">The level of salts and minerals in the water is affected by the rising water table.
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Land clearing and irrigation (inclusing domestic lawn watering) create high water tables and high salinity.
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Salinity affects agriculture.

<span style="font-family: Tahoma,Geneva,sans-serif;">** Climate change activity card ** <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Climate change can affect vegetation and habitats.
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Climate change can change the flora and fauna.
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Human activity can contribute to climate change.

<span style="font-family: Tahoma,Geneva,sans-serif;">** Stormwater activity cards ** <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Stormwater systems carry litter and other residential rubbish, which can wash down gutters and drains.
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Sewerage systems can overload into the stormwater system.

<span style="font-family: Tahoma,Geneva,sans-serif;">** Vegetation activity cards ** <span style="color: #008000; font-family: Verdana,Geneva,sans-serif;">
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Trees and plants play a vital role in the health of our waterways
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Removing trees allows more water to reach the groundwater system.
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Vegetation protects the fragile river banks from collapsing and forms a buffer between land and the waterway.
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Plants in and around the water provide habitats for animals, as well as shading the river and slowing the flow.

<span style="font-family: Tahoma,Geneva,sans-serif;">** Water temperature activity cards ** <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Cold water holds more oxygen.
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Warm water results in the growth of plants and algae.
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Turbid (mudd) water heats up more quickly than clear water.
 * <span style="color: #000000; font-family: Tahoma,Geneva,sans-serif;">Cutting trees along river banks raises water temperature.
