Have you ever wondered what would happen if the sun suddenly disappeared? Let’s explore this fascinating idea together!
The sun is incredibly important because its huge mass and gravitational pull keep all the planets, including Earth, in their orbits. If the sun were to vanish, Earth would no longer follow its usual path. Instead, it would start moving in a straight line into space.
Without the sun, Earth would become dark after about 8 minutes, which is the time it takes for sunlight to reach us. The moon would also disappear from view because it doesn’t produce its own light; it only reflects the sun’s light.
Plants would be in big trouble without sunlight because they need it for photosynthesis, the process that helps them make food. Without photosynthesis, plants would die, and soon after, the Earth’s temperature would drop dramatically. Within a week, it would fall below 0 degrees Fahrenheit, and within a year, it could reach negative 100 degrees Fahrenheit, making it impossible for humans to survive.
While the surface of the oceans would freeze, the water deep inside might stay liquid due to heat from Earth’s core. Some tiny organisms that don’t need sunlight could survive by using this heat for energy. However, without the sun, humans and most other life forms wouldn’t be able to exist.
Did you know that the Eiffel Tower, made mostly of iron, changes height with the seasons? In summer, it can grow about 17 centimeters taller due to thermal expansion. This happens because heat makes the particles in iron move faster and take up more space.
Here’s another cool fact: grasshoppers hear through their bellies! They have special hearing organs called tympanums and air-filled sacs that help them listen. This system is so accurate that male grasshoppers can find females just by hearing their calls. The pitch of a grasshopper’s call can even tell others about its size. If a call sounds like it’s from a large grasshopper, other males might avoid its territory to prevent fights, while females might respond to the call.
Did you know that it might rain diamonds on planets like Jupiter and Saturn? These planets have atmospheres rich in methane. During storms, lightning turns methane into soot. As the soot falls, it faces high temperatures and pressures, turning into graphite and eventually into diamonds. Imagine diamond rain!
Isn’t our universe full of amazing wonders? From the sun’s vital role to the possibility of diamond rain, there’s so much to learn and explore!
Gather materials like foam balls, paint, and string to create a model of the solar system. Show how the planets orbit the sun and discuss what would happen if the sun disappeared. This hands-on activity will help you understand the sun’s gravitational pull and its importance in keeping planets in orbit.
Conduct an experiment to see how plants react to the absence of sunlight. Place one plant in sunlight and another in a dark area. Observe the changes over a week. This will help you learn about the role of the sun in photosynthesis and plant survival.
Use a thermometer to measure the temperature in a sunny spot and a shaded area. Discuss how the absence of the sun would affect Earth’s temperature. This activity will help you understand the drastic temperature changes that would occur if the sun disappeared.
Learn about thermal expansion by measuring a metal object at different temperatures. Discuss how this concept explains the Eiffel Tower’s height change. This activity will help you understand how heat affects materials on Earth.
Watch a video or read about how diamonds might form on Jupiter and Saturn. Create a drawing or model to illustrate the process. This activity will help you explore the fascinating phenomena that occur in our universe.

It’s AumSum Time! What if the sun disappeared? We would need a lot of flashlights. No. The sun’s enormous mass and gravitational power keep the planets in their orbits. If the sun disappeared, the Earth would move in a straight line into space. The Earth would be plunged into darkness after about 8 minutes, as that is how long sunlight takes to reach us. The moon would also vanish since it doesn’t produce light on its own.
Plants would die without sunlight, as photosynthesis would cease. Within a week, the Earth’s temperature would drop below 0 degrees Fahrenheit, falling to negative 100 degrees Fahrenheit within a year, making survival impossible. Ocean surfaces would freeze, but water in the interior would remain liquid due to heat from the Earth’s core. Only microorganisms that do not require photosynthesis would survive by converting the core’s heat into the energy they need. Thus, without the sun, humans would not exist.
What happened? AumSum to the rescue! The Eiffel Tower is mostly made of iron and its average height is about 324 meters. Surprisingly, during summer, its height increases by about 17 centimeters. Why? Because of thermal expansion. As iron heats up, the kinetic energy of its particles increases, causing them to vibrate faster and occupy more space, which makes the tower taller.
Did you know that a grasshopper hears through its belly? It has hearing organs called tympanums and air-filled sacs that help it hear. This mechanism is so precise that male grasshoppers can pinpoint a female’s location just by hearing her mating call. Additionally, from the pitch of a grasshopper’s call, others can determine its size. If it sounds large, males may avoid its territory to prevent fights, while females respond to mating calls.
Now, about diamonds! Scientists believe that it can actually rain diamonds on Jupiter and Saturn. These planets have methane-rich atmospheres. During storms, lightning converts methane in the clouds into soot. As the soot falls, it is subjected to intense temperatures and pressures, which compress it into chunks of graphite. As the pressure increases, the graphite is transformed, resulting in diamond rain.

Sun – The star at the center of our solar system that provides light and heat to the planets orbiting it. – The sun is essential for life on Earth because it provides the energy needed for plants to grow.
Earth – The third planet from the sun in our solar system, which is home to all known life. – Earth is unique because it has the right conditions to support a wide variety of life forms.
Plants – Living organisms that typically grow in soil and use sunlight to make their own food through a process called photosynthesis. – Plants are important because they produce oxygen and food that other living things need to survive.
Photosynthesis – The process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll. – Photosynthesis allows plants to convert sunlight into energy, which they use to grow and thrive.
Temperature – A measure of how hot or cold something is, usually measured in degrees Celsius or Fahrenheit. – Scientists use thermometers to measure the temperature of the air and water in different environments.
Oceans – Large bodies of saltwater that cover most of Earth’s surface and are home to a wide variety of marine life. – The oceans play a crucial role in regulating Earth’s climate and weather patterns.
Heat – A form of energy that is transferred between objects with different temperatures, often felt as warmth. – When you touch a warm cup of cocoa, you can feel the heat being transferred to your hands.
Diamonds – Hard, transparent crystals made of carbon that are formed deep within the Earth under high pressure and temperature. – Diamonds are often used in jewelry because of their brilliance and durability.
Gravity – The force that attracts objects toward each other, especially the pull of the Earth that gives weight to objects and causes them to fall when dropped. – Gravity is the reason why we stay grounded and don’t float off into space.
Space – The vast, seemingly infinite area beyond Earth’s atmosphere where stars, planets, and other celestial bodies exist. – Astronauts travel to space to explore and learn more about our universe.
