Water Resource Management Quiz

To be successful on Survival Island, you need to figure out how much water is available on the island and the best ways to use the water resources. Each person requires an average of 10 gallons of water each day for all their activities, but less than one gallon is used each day for drinking. Identify two other human activities that require the use of water and could help explain the difference between total water usage (10 gallons) and drinking water usage (1 gallon).

Each summer, rainfall decreases so that a single rain barrel cannot provide enough water for the population. Use your understanding of water resources to help the group identify different ways to address water supply problems during the summer.

Identify activities that could add water resources to help solve the problem. Choose all answers that apply.

• build another rain barrel or a larger rain barrel

• dig a well or find a spring to get groundwater

• make sure all the group members drink plenty of water

• purify (desalinate) ocean water for drinking/cooking

• each person reduces the amount of water they use each day for brushing their teeth

• the group shares water for some activities, like cooking or washing dishes

• ask the Survival Island owners to provide extra water during the summer months

A partial model of the water supply system is shown in Figure 2. Complete the model by adding the following:

- Arrows to show the path of the water from the water source to the kitchen

- A labeled symbol to show a solution to the problem of sediment in the water.

In one of the houses on the island, the drinking water looks clear but tastes like coconut! The house gets its water from the nearby river (see Figure 3 to the right). There are two groups of coconut trees along the river, North Grove and South Grove.

Tasting like coconut is a property of water caused by: _________. Choose one answer below.

• removing contaminant molecules from water

• water molecules that are shaped like coconuts

• coconut contaminant molecules dissolved in the water

• the number of water molecules in a sample

A house located on the other side of the island has clear drinking water with a salty taste. What would best describe why water in one location on the island tastes like coconut and water at a different location tastes salty? Choose one answer below.

• The environment (e.g., rocks, soil, plants) where the water resource is found causes the difference in taste.

• The taste of water is a random property, so every water sample on the island will have a different taste.

• The amount of water collected as a sample causes the difference in taste.

• The difference in taste occurs because different water molecules have different flavors.
