Topic: Water


  1. Water 💧 is a clear liquid that we drink and use for many things.
  2. It has no color or taste, and it’s very important for life.
  3. Example: When you drink from a glass, you’re drinking water.


  1. Water comes from different places 🌊.
  2. It can be in rivers, lakes, and big oceans.
  3. You also get water from your tap at home or a bottle.
  4. Example: The water in a lake or river is not the same as juice or soda 🥤.

Water is everywhere! It’s clear, tasteless, and helps us live. We find it in rivers, lakes, oceans, taps at home, and bottles. It’s not like colorful juices or sodas. 💦🏞️🚰

Distinguishing Water from Other Liquids:

Water and other liquids can be different in several ways. Let’s see how we can tell them apart:

  1. Color: 🌈 Water is clear and doesn’t have any color. But other liquids, like orange juice or cola, have colors.
  2. Taste: Water doesn’t have a taste, but juice, milk, and soda have different flavors. For example, orange juice is sweet and tastes like oranges 🍊.
  3. Transparency: Water is see-through, which means you can look through it and see things on the other side. Most other liquids are not transparent.
  4. Use: We use water for drinking and cleaning. We use juice for drinking and for its taste. Milk is good for our bones, and soda is for special occasions.

So, if something is clear, has no taste, and you can see through it, it’s probably water! 💧🥤🍊
