Water Cycle In A Bag Activity

Water Cycle In A Bag Activity

Do your kids question you why it rains?  Or perhaps how clouds appear in the sky?  Spend a day with your kids to educate them with this easy to do a science activity where you and your kids will create a water cycle in a bag! This is also an excellent activity for elementary science classes. Imagine your window covered in your kid’s shimmering water cycle experiments! You have to follow simple, step-by-step directions to create something fun and informative with your kids today. This hands-on activity will get your kids fascinated about science and wanting to learn more about weather science.

About Water Cycle In A Bag Activity

Has your kid ever asked you where rain comes from? What’s the water cycle? Well, rain is an essential part of the water cycle. It’s the pattern of how water flows through our atmosphere. The sun warms water on Earth and makes it evaporate into a gas. This gas assembles in the sky as clouds. The water in the clouds then compresses, or changes back into a liquid, and comes back to the Earth as rain. It can be difficult to witness the whole water cycle in real life, but you can build a smaller model at your own home! If you’re on the lookout for an easy, playful kids’ science activity, you’re in the right spot! This water cycle in a bag is a quick prep science activity with a BIG payoff. This engaging science activity helps kids learn about the water cycle with a simple experiment that only needs a sealable plastic bag, permanent marker, optional blue food coloring, and water.

Materials Required For Water Cycle In A Bag Activity

  • A sealable sandwich bag
  • Blue food coloring
  • A permanent marker
  • Sticky tape
  • Water
  • A teaspoon

Steps Involved In The Water Cycle In A Bag Activity

1. First of all, put some water in a container and add a teaspoon of blue food coloring.

2. Now stir well.

3.  After this, take the sealable sandwich bag and draw a sun, some clouds, sea and a bit of land with trees, etc, you can also color the sun and the land and trees if you want to.

4. Now, pour the blue water into the bag and seal it.

5. Attach the bag on a sunny window with the help of the tape.

6. Now, leave the bag on the window for a while and examine what changes occur when the sun begins to heat up the water. Finally, you will start to view the droplets of water sticking to the side of the bag. Some of these will be up high in the clouds while other droplets will be on their way back down.

The Science Behind It

You might be wondering about the science behind it. It’s because the water in the bag is being warmed up against the sunny window. That water transforms into a gas through the process known as evaporation. In nature, evaporated water vapor goes into the atmosphere, but in our bag, it has nowhere to go, so it ends up adhering to the sides of the bag, rolling back into a liquid as condensation. That evaporated water then slides back into the pool of water below as “rain”.

Just keep checking back on your activity a few times a day, or anytime it’s sunny to observe the water cycle development! With some simplistic materials and a weekend afternoon, you and your kids can have a fabulous time learning about the water cycle together.
