Fish need oxygen to breathe, just like we do, but they get their oxygen from the water. When the water gets too hot, it can’t hold as much oxygen. This makes it hard for fish to breathe. Also, when the water is warmer, fish use up oxygen faster because their bodies work harder. If the oxygen level gets too low, fish might not survive. That’s why it’s important to keep the water temperature in an aquarium just right. Using a filter or a bubbler can help by moving the water around and adding more oxygen, which keeps the fish healthy.
Have you ever noticed that ice cubes from your freezer are often cloudy? This happens because the water we use has tiny minerals and gases dissolved in it. When the water freezes, ice forms from the outside in, pushing these minerals and gases to the center. When the center freezes, it traps them, making the ice look cloudy. To make clear ice, some special ice makers freeze water slowly, layer by layer. This lets the minerals and gases escape before the water turns into ice, resulting in clearer ice cubes.
Our bodies are made up of about 60% to 80% water, which is super important for things like digestion and getting rid of waste. Every day, we lose about 2 to 3 liters of water through sweating, peeing, and even breathing. If we don’t drink enough water to replace what we lose, we can get dehydrated. This can cause headaches, make us feel tired, and give us a dry mouth. If we stay dehydrated for too long, it can lead to serious health problems and can even be dangerous.
Every year, many birds travel long distances to find food and escape bad weather. Scientists are still figuring out exactly how they do it, but they think birds can sense the Earth’s magnetic field, which helps them know which way to go. Birds might also use landmarks like mountains and rivers to help them navigate. Plus, they might look at the sun and stars to guide them on their journey. It’s amazing how these birds can travel so far and find their way!
Conduct a simple experiment to see how temperature affects oxygen levels in water. Fill two jars with water and place one in a warm area and the other in a cool area. After a few hours, use a dissolved oxygen test kit to measure the oxygen levels in each jar. Discuss why the warm water holds less oxygen and how this impacts fish.
Imagine you are a fish living in a pond where the water temperature suddenly rises. Write a short story about your experience, describing how the change in temperature affects your ability to breathe and your daily life. Share your story with the class.
Make ice cubes using tap water and distilled water. Observe the differences in clarity once they are frozen. Discuss why the ice made from distilled water is clearer and relate this to the concept of dissolved minerals and gases.
Keep a diary of your water intake for a week. Record how much water you drink each day and note any changes in how you feel. At the end of the week, discuss the importance of staying hydrated and how it affects your body.
Choose a migratory bird species and research its migration route. Create a map showing the bird’s journey, including key landmarks it might use for navigation. Present your map to the class and explain how the bird finds its way.

**It’s AumSum Time!**
**Why is hot water harmful for fish?**
Hot water can be harmful to fish because most fish rely on oxygen dissolved in water for respiration and metabolism. As the temperature of the water increases, the solubility of gases, including oxygen, decreases. This means that warmer water holds less oxygen, making it difficult for fish to breathe. Additionally, higher temperatures can increase the fish’s metabolism, leading to a greater oxygen requirement. If the oxygen levels drop too low, fish can suffocate and potentially die. Therefore, it’s important to monitor and maintain the water temperature in an aquarium. Using a filter or bubbler can help circulate and add oxygen, promoting the health of the fish.
**What makes ice clear or cloudy?**
When we make ice at home, we typically use room temperature tap water, which contains dissolved minerals and gases that are not visible to the naked eye. As the water freezes, the temperature drops, and ice begins to form from the outside. The dissolved minerals and gases are pushed toward the unfrozen center, and when the center finally freezes, these trapped substances become visible, resulting in cloudy ice. To create clearer ice, some specialized ice makers freeze water slowly, layer by layer. This method allows minerals and gases to escape before the water completely freezes, resulting in clearer ice.
**What if we stopped drinking water?**
The human body is composed of about 60% to 80% water, which is essential for various bodily functions, including digestion and excretion. We lose about 2 to 3 liters of water daily through sweat, urine, and breathing. If we do not drink enough water to compensate for this loss, we can become dehydrated. Dehydration can lead to symptoms such as headaches, nausea, dry mouth, and decreased energy levels. Chronic dehydration can result in severe health issues and, in extreme cases, can be life-threatening.
**How do migratory birds find their way?**
Every year, many migratory birds travel thousands of kilometers to find food and avoid extreme weather. While researchers are still studying how these birds navigate, it is believed that they can detect the Earth’s magnetic field lines, which run from the south pole to the north pole. When migrating, birds may align themselves with these magnetic field lines. Additionally, they may create mental maps of their routes using natural landmarks like mountains and rivers. It is also thought that migratory birds use the positions of the sun and stars to help guide them to their destinations.

This version removes informal language and maintains a more neutral tone while preserving the key information.
Fish – A cold-blooded animal that lives in water, has gills, and usually has fins and scales. – Many fish swim in the river, using their fins to move through the water.
Oxygen – A gas that is essential for most living organisms to breathe and survive. – Plants produce oxygen during photosynthesis, which is important for animals to breathe.
Water – A clear liquid that is essential for life, covering most of the Earth’s surface. – All living things need water to survive, and it is found in rivers, lakes, and oceans.
Ice – Frozen water, a solid form of water that is cold and hard. – In winter, the pond turns to ice, and we can see animals like polar bears walking on it.
Minerals – Natural substances found in the earth that are important for the health of living organisms. – Plants absorb minerals from the soil, which help them grow strong and healthy.
Gases – Substances like air that are not solid or liquid and can fill any space. – Carbon dioxide and oxygen are examples of gases that are important for life on Earth.
Drink – To take liquid into the mouth and swallow it. – Animals drink water from streams and lakes to stay hydrated and healthy.
Dehydrated – When a living thing loses more water than it takes in, leading to a lack of water in the body. – If you don’t drink enough water, you can become dehydrated, which is not good for your health.
Birds – Warm-blooded animals with feathers, wings, and beaks, most of which can fly. – Birds build nests in trees and sing beautiful songs in the morning.
Navigate – To find the way to a place, often used to describe how animals move from one location to another. – Many birds navigate long distances during migration, using the stars and the Earth’s magnetic field.
