Lesson Number
Lesson Aims
1: Introduce Unit: What do we know about water?
Students explore water and access, and how it is treated in Australia. We play a game exploring the different types of water, Students write about water, what they know what they want to know and what interests them.
Introduction/ Engagement Session: Students discuss what and water use and access around the world.
2: How much water is available for human use?
Through a classroom demonstration, students will calculate the percentage of fresh water available for human use and explain why water is a limited resource.
Students are encouraged to ask questions, and are expected to conclude that that freshwater is limited and must be conserved and protected.
3. How much water do we need?
How can we reduce our consumption?
Practical investigation into water consumption. Students begin Investigation. Students collect data about their personal and family water use. They use their data to identify where water consumption could be reduced.
The amount of water required for different activities varies greatly. The collected data shows which activities require the most water.
4. Access to Fresh Clean Drinking Water
This lesson addresses the issue of differences in the availability, use and consumption of water in Australia and in Central

2). Students will continue to learn about the importance of water and the different ways water is used in everyday lives in some African nations, and will examine the consequences communities face when they lack clean
“Last Call at the Oasis” is a documentary about our world’s water crisis. The film discusses how many large cities in America are getting closer to use up their available water, how many areas across the globe do not have access to drinking water and are forced to drink contaminated water, how water shortages are causing acts of violence and are causing stress to agricultural communities, and a possible solution of using recycle water to stop us from wasting so much water. The film goes around the globe to talk to scientists who are studying contaminated water, people who have become very sick due to this water, and to the agricultural community in Australia where, unfortunately, some farmers have take their own lives due to water shortages.
how the water is distributed to the consumer. There are different expectations on how the water
The water that supplies Western Australia comes from a variety of sources, including surface water and groundwater. Recent technologies have emerged which allow WA to use water sources that were previously unusable, such as desalinated ocean water and recycled wastewater (Government of Western Australia, 2012). The scale for this report is the state of Western Australia. This scale will allow for analysis of more elements of water consumption in Perth and its surrounding areas, not just the city’s consumption of water, but consumption from other key industries that fuel the economy of Perth and WA, including mining and agriculture.
Water has become a very controversial issue in the United States and around the world. As populations increase and resources decrease, the way we use our resources and keep populations safe become more and more important. Throughout the world there are nearly 1.1 billion people who do not have access the clean drinking water. 5 Most of these 1.1 billion people are located in poor areas and do not have the financial means to build the infrastructures needed to provide water to the citizens of their country. 5 Drinking water is an essential part of our everyday life. People must have water to survive, but it must be clean and safe to consume.
One out of five children suffer from starvation and thirst all around the world. But suffering from thirst isn 't so common in the U.S because one way or another water is easy to find. Many people all over the world take purified water for granted and see it as something they will always have. In Africa the people dream of having drinking water in their daily lives. Contaminated water affects many people from Africa. Such as health issues, pollution, and starvation. Africa civilians are one of the top countries in the world that suffer the most from starvation and dehydration.
This is because only a small part of the population, particularly in developing countries, have access to water of acceptable quality. It is estimated that in some countries only 20% of the rural population has water of satisfactory quality. Based on these statistics, it is clear the urgent need for awareness about caring for water use. Almost without realizing it, we are seriously jeopardizing this essential resource, not for us but for our children's children and their generations, aware that in other parts o...
Introduction on Water It covers 70% of our planet, makes up 75% of our body, it is necessary for survival and it is declining at a rapid rate (http://www.sscwd.org). It is water. Unfortunately, clean water is rare, almost 1 billion people in developing countries do not have access to water everyday. “Yet, we take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles” (The Water Project). Use of earth’s natural resources should be seen as prosperity, although it is taken for granted, every aspect of daily life revolves around the environment, forcing water conservation to be necessary for future on this planet.
Another problem for people of Africa is clear access to clean water. Clean drinking water is very rare for the people of Africa. Unclean water and sanitation problem leads to many diseases in African countries. Main problem which occurs due to unclean water is child morality. Around 2000 children’s die from diarrhoea which spread due to poor sanitatio...
There is a global shortage of drinking water. A person might wonder how this can be if seventy percent of the earth’s surface is covered by water. Most of the Earth’s water is unsuitable for human consuption. Ocean water is salt water, which makes up 97.5% of all water on the planet. Freshwater is only 3.5% of all the water on Earth. Drinking water is sourced from bodies of freshwater.
The combination of safe drinking water and hygienic sanitation facilities is a precondition for health and for success in the fight against poverty, hunger, child deaths and gender inequality. UNICEF works in more than 90 countries around the world to improve water supplies and sanitation facilities in schools and communities, and to promote safe hygiene practices. All UNICEF water and sanitation programmes are designed to contribute to the Millennium Development Goal for water and sanitation: to halve, by 2015, the proportion of people without sustainable access to safe water and basic sanitation. Key strategies for meeting the water, sanitation and hygiene challenges are to:
Water scarcity is harmful to human life because when water is poorly managed throughout the world, those who need water are deprived of nutrients they truly need, causing them to die. This eventually affects the global population. Therefore, many experts have proposed several solutions such as the LifeSaver Bottle, TrojanUVPhox treatment system, and Waste Water Recycling. The problem of water scarcity has increasingly spread throughout the world as of yet, The UN reports that within the next half- century up to 7 billion people in 60 countries which is more than the whole present population will face water scarcity (Sawin “Water Scarcity could Overwhelm the Next Generation”). As well, the demand for freshwater has tripled over the past 50 years, and is continuing to rise as a result of population growth and economic development.
Water is the most priceless resource on our planet. Billions of gallons flow through our rivers and lakes. Millions of gallons are consumed by humans each day. Our world’s surface is seventy percent water. With so much water around us, how can 1.1 billion people still lack access to clean water (Cooper, Water Shortages)? People are already using fifty four percent of all the freshwater available on this planet (Cooper, Water Shortages). We cannot afford to neglect something so essential to our very survival. We must defend our most important natural resource—water.
Many of these in later years shall need to be addressed as tension rises: Saving and consumption of water Improving drinking water supply Increasing access to clean water supply Decreasing tension between war-ing nation over resources With the population expected to rise 40-50% within the next 50 years, the demand for water in Agricultural needs and Environmental needs will rise as well, creating a more desperate water crisis. Developed countries struggle with managing water consumption. Our high demand in agriculture, industry, and domestic use further complicates this issue. With increasing urbanization and extravagant changes in lifestyle, our use and wasting of water will only increase.
Water is one of the most essential non-renewable natural resources on the Earth. Technically, an un-hydrated human being can live no more than three days. In the United States, people consume water mainly from tap water and bottled water. However, the consumption between these two sources is not even, but lean to one side heavily. According to the Natural Resources Defense Council, people consume from 240 to over 10,000 times more per gallon of bottled water than they usually do for tap water.
