Water Cycle

-

 

Water is essential to all living beings because it is used to hydrate plants, animals, and humans. Living beings find water in lakes, rivers, oceans, and man-made reservoirs.

The forms of water are solid, liquid, and gas. Ice is a solid form, rain is a liquid form, and vapor is a gas form. Water becomes solid at 0 degrees Celsius and becomes vapor at 100 degrees Celsius. Snow helps control the Earth's temperature, water vapor forms clouds, and rain fills up reservoirs.

Water on Earth's surface, such as in oceans or seas, gets heated by the sun and becomes vapor. This is called evaporation. When the vapor cools, it becomes water droplets through a process called condensation. It takes millions of water droplets to form raindrops. When the droplets become heavy, they fall as rain. However, when the droplets freeze due to the temperature inside the cloud, they fall as snow, hail, or sleet. This process is called precipitation.
Changes in the climate can affect the water cycle. This is called global warming. It can be caused by pollution and deforestation. But we can solve that! We can use clean fuels and plant more trees. Doing these things can help save the water cycle and prevent flooding and droughts.

Birthday 2025

  Dear grandpa, My 9th birthday is coming up very soon, so in this letter that I am writing to you, I am going to tell you what I wish to do on my 9th birthday. (from morning to evening). When I wake up in the morning, the first thing  I will do is shout "It's my birthday!" Then I will go brush my teeth like I usually do. Then I will so some chitchatting with my parents for 5-10 mins, and then I wish to head to IHOP (a pancake place) to have breakfast.  After having breakfast, we will go home and I will read a book. In the afternoon, after having lunch which might be paneer and pulav that I'm hoping my Mother will make for me, I wish for my parents to take me to the mall so  I can get a hoverboard, a keychain, a soccer ball, and a LEGO set. After doing those, we will head home so my parents can rest for a while, while they do so I can do some drawing. In the evening we will head to the Living waters church to have some fun, worship, and have a big feast! I am looking...

How does it work - Maglev Train & Scrap Yards

-
Image
  Have you ever been on a maglev train or worked in a scrapyard and wondered "How do these things work?" I will write about how maglev and scrap magnets get into action. The maglev trains and scrap magnets work by using electromagnets . The maglev train has U-shaped undercarriage which gets attracted by the track due to magnetism, so the train moves along the rails. There are guidance magnets in the train which include magnetic repulsion; they help direct the train to either left or right, or stop the train from crossing the tracks and falling down. The driver is not the only one driving the train! In fact , there are levitation magnets which have computers controlling them in order to slow down the train, keep it on the track, and move the train. In a scrapyard, there will be a crane with the magnet which picks up car scraps. It also has an iron disc which is armored with an electric coil to pick up the scraps. It has a switch to turn on so the magnet works just like ...

Dolphins

  Dolphins are very intriguing creatures. In this passage, I am going to explore some fascinating facts about dolphins. The first remarkable fact about dolphins is that they are really smart. A dolphin's trainer might use hand signals to represent objects. For example, the trainer would throw a ball into the water and signal, "Is there a ball?" The dolphin would respond with a "yes." Then, the trainer might point to a broken vase and signal, "Is the vase broken?" The dolphin would answer "no." Dolphins are intelligent enough to remember the hand sign for an unbroken vase and respond correctly. The another remarkable fact about dolphins is that they can communicate with each other, just like humans. But instead of using English, they rely on motions and sounds to communicate. For example, if one dolphin puts its flipper on another dolphin's back, it means they are friends. If two dolphins jump at the same time, it shows that they are bon...
