Dolphins are amazing creatures known for their intelligence. They are part of a group of animals called cetaceans, which also includes whales and porpoises. Over millions of years, these animals have evolved into the complex beings we see today, with dolphins having large and intricate brains.
Dolphins are known for their social skills, which are quite similar to humans. For example, bottlenose dolphins often work together when hunting. One dolphin might stir up the seabed to create a ring of mud around a group of fish. As the ring gets smaller, it traps the fish, and the other dolphins line up to catch them as they try to escape.
Dolphins have a special ability called echolocation, which helps them find their way, especially in murky waters. They make high-frequency sound waves that travel through water, bounce off objects, and return as echoes. This helps them figure out where things are and what shape they are. Dolphins also communicate using low-frequency sounds and have unique whistles, like names, to call each other. Some studies even suggest that dolphins can recognize themselves in mirrors, showing a level of self-awareness not often seen in other animals.
Vaccines are important for keeping us healthy. They train our bodies to fight against harmful germs. Vaccines usually contain weakened or dead germs that trigger an immune response without making us sick. Our immune cells recognize these germs as invaders and produce antibodies to fight them off. These immune cells also remember the germs, so if we encounter them again, our bodies can respond more effectively.
Pop rocks are a fun candy that pops in your mouth! They are made from sugar, water, corn syrup, and flavorings. The ingredients are mixed and heated until most of the water evaporates, creating a thick syrup. Then, highly pressurized carbon dioxide gas is added to the syrup, which is cooled to form hard candy. When the candy dissolves in your saliva, the pressurized carbon dioxide escapes from the bubbles, creating the popping sensation.
Sunsets are beautiful and often have a red color. This happens because of the way light scatters in the atmosphere. Our atmosphere is made up of tiny particles of nitrogen and oxygen. When sunlight, which contains seven colors, passes through the atmosphere, it scatters blue and violet light more than red and orange light. During sunset, sunlight travels through a greater distance in the atmosphere, scattering most of the blue and violet light before it reaches our eyes. This allows the less scattered red and orange light to dominate, giving sunsets their beautiful colors.
A black umbrella is useful in summer because it absorbs most of the sunlight, including ultraviolet radiation. While it gets heated, it also radiates heat back into the air, making it a practical choice for staying cool in hot weather.
Imagine you are a dolphin! Work in small groups to create a short skit demonstrating how dolphins use their social skills to hunt. One student can be the dolphin stirring up the seabed, while others line up to catch the fish. Perform your skit for the class and discuss what you learned about dolphin teamwork.
Create a simple echolocation experiment using a blindfold and a small object. One student will be blindfolded and use sound clues provided by classmates to locate the object. Discuss how dolphins use echolocation in the ocean and compare it to your experience.
Develop your own “dolphin language” using whistles and clicks. Pair up with a classmate and try to communicate a simple message using only these sounds. Reflect on how dolphins might use similar methods to communicate in the wild.
Research and create a poster about the intelligence of dolphins. Include facts about their brain size, problem-solving abilities, and self-awareness. Present your poster to the class and explain why dolphins are considered intelligent animals.
Learn about the mirror test for self-awareness. Set up a mirror and observe how different animals or pets react to their reflection. Discuss how dolphins might recognize themselves in mirrors and what this tells us about their cognitive abilities.

**It’s AumSum Time!** Can you guess the title of my next video? Hurry up! Write your guess in the comments section below.
**Are dolphins smart?** Yes, dolphins are indeed intelligent creatures. They belong to the family of cetaceans, which includes aquatic animals like whales and porpoises. Over millions of years, cetaceans have evolved into the complex beings we see today, including dolphins with large, intricate brains.
Dolphins exhibit various functions that are typically not seen in other animals. One such function is their ability to socialize in a human-like manner. For example, bottlenose dolphins often work together to hunt. One dolphin can stir up the seabed to create a circular ring of mud around a shoal of fish. As the ring gets smaller, it traps the fish, and the other dolphins line up to catch them as they try to escape.
In addition to their social skills, dolphins possess the ability to echolocate, which helps them navigate, especially in murky waters. They produce high-frequency sound waves that travel through water, bounce off obstacles, and return as echoes. This allows them to identify the location and shape of objects around them. Dolphins also communicate using low-frequency sounds and have unique signature whistles, similar to names, to call each other. Studies suggest that dolphins can even recognize themselves in mirrors, indicating a level of self-awareness not commonly found in other animals.
**Now, let’s talk about vaccines.** How do vaccines work? Vaccines train our bodies to fight against harmful pathogens. They often contain weakened or dead pathogens that trigger an immune response without causing the disease. Our immune cells recognize these pathogens as foreign invaders and produce antibodies to eliminate them. Additionally, these immune cells remember the pathogens, allowing our bodies to respond more effectively if exposed to the same pathogens in the future.
**Why do pop rocks pop?** Pop rocks are tiny candy crystals made from sugar, water, corn syrup, and flavorings. The ingredients are mixed and heated until most of the water evaporates, resulting in a thick syrup. For pop rocks, highly pressurized carbon dioxide gas is added to the syrup, which is then cooled to form hard candy. When the candy dissolves in saliva, the pressurized carbon dioxide escapes from the bubbles, creating the popping sensation.
**Why are sunsets red?** The red color of sunsets is due to the scattering of light in the atmosphere. Our atmosphere consists of tiny nitrogen and oxygen particles. When sunlight, which contains seven colors, passes through the atmosphere, it scatters blue and violet light more than red and orange light. During sunset, sunlight travels through a greater distance in the atmosphere, scattering most of the blue and violet light before it reaches our eyes. This allows the less scattered red and orange light to dominate, giving sunsets their beautiful colors.
**Lastly, why do we use a black umbrella in summer?** A black umbrella is effective in summer because it absorbs most of the sunlight, including ultraviolet radiation. While it gets heated, it also radiates heat back into the air, making it a practical choice for staying cool in hot weather.
