lesson 2
Objective: By the end of the lesson, students will be able to investigate the characteristics and spatial distribution of global water resources, including the classification of water resources and the identification of different forms of water used as resources. They will also be able to create visual representations and examine spatial distribution patterns of water resources.

Definition of a Water Resource: Water resources are natural sources of water that are essential for human survival and development.
Water is something we all need to live and grow. It's very important for people, animals, and plants. But did you know that most of the water on Earth is salty and not good for drinking or farming? The water we can use is called fresh water, and there's not a lot of it. In some places, there isn't enough water for everyone. Even where there is enough, we have to be careful not to waste it. We use water for many things, like drinking, washing, and growing food. So, we need to take care of our water and use it wisely to make sure there's enough for everyone. |
Water resources are not all the same and cannot be used interchangeably. Most of the water on Earth is salt water, which is not suitable for drinking or farming. Only about three percent of the water on Earth is fresh water, and the majority of this is frozen in glaciers and polar ice caps. The remaining fresh water is found as groundwater, in rivers, lakes, and in the air. Human activities depend on fresh water for drinking, agriculture, industry, and maintaining healthy ecosystems. It's important to understand that different water sources have different uses and must be managed carefully to meet the various needs of people, animals, and plants.
- Why is it important to manage and use water resources wisely?
- What are some of the uses of fresh water mentioned in the text?
- How does the text explain the distribution of fresh water on Earth?
Lesson 3
the spatial distribution of water
The spatial distribution of water resources varies globally and within countries due to a combination of factors, including:
In summary, the spatial distribution of water resources is influenced by a complex interplay of physical, ecological, and human factors, making it difficult to predict and manage water availability in different regions.
- Climate and weather patterns: Different areas of the world receive varying amounts of precipitation, with some regions receiving higher rainfall and others experiencing drought.
- Geography: The distribution of water resources is heavily influenced by physical geography, such as the presence of rivers, lakes, and aquifers. Mountainous regions tend to have higher water availability due to precipitation and snowmelt, while coastal areas often experience water scarcity due to the high demand for water for irrigation and other uses.
- Human activities: Human activities, such as dam building, water diversions, and groundwater pumping, can impact the distribution of water resources by altering the natural flow of water and affecting the availability of water in certain areas.
- Soil and vegetation: Soil type and vegetation can influence the availability of water in different regions. For example, soils with high permeability tend to allow for greater water infiltration and retention, while soils with low permeability are more likely to result in runoff and water scarcity.
- Political and economic factors: Political and economic factors, such as water management policies and water allocation agreements, can also impact the spatial distribution of water resources. For example, some countries may prioritize water allocation for agricultural production, while others may prioritize urban water supply.
In summary, the spatial distribution of water resources is influenced by a complex interplay of physical, ecological, and human factors, making it difficult to predict and manage water availability in different regions.

To explain what drives ocean currents, we can use a simple analogy. Imagine a big bathtub with water and a few toys floating in it. When you move your hand back and forth in the water, the toys will move along with the water in a certain direction, right? This is similar to how ocean currents work.
Ocean currents are driven by a few things, including:
Overall, ocean currents play an important role in regulating the Earth's climate and weather patterns by transporting heat, nutrients, and water from one part of the ocean to another.
Ocean currents are driven by a few things, including:
- The wind: Just like how you move your hand in the bathtub, the wind can blow on the surface of the ocean and create currents.
- Differences in water temperature and saltiness: Cold water is denser than warm water, and water that has more salt is denser than water with less salt. When cold or salty water sinks to the bottom, it can create currents that flow along the ocean floor.
- The Earth's rotation: The Earth spins on its axis, and this rotation affects the direction of ocean currents.
Overall, ocean currents play an important role in regulating the Earth's climate and weather patterns by transporting heat, nutrients, and water from one part of the ocean to another.
