Observe the Bags After 1 Hour

Do your kids ask you why it rains?  Or maybe how clouds happen?  Spend an afternoon didactics them with this easy to practise science experiment where you and your kids volition make a water wheel in a pocketbook!

Water Cycle In a Bag Science Experiment for Kids

This is also a great action for elementary science classes.  Imagine your window covered in your student's shimmering h2o cycle experiments!

Follow these simple, footstep-by-stride directions to create something fun (and educational) with your kids today.


Watch this video to meet how it's done:

Step 1: What Y'all'll Need

You demand just a few mutual household items to create your h2o bike display:

  • Plastic aught lock-way bag

  • Permenant marker(s)

  • H2o

  • Bluish food coloring

  • Clear tape

You'll need food coloring, water, a plastic bag, a permenant marker, and tape

Pace 2: Decorate the Bag

Earlier yous do anything else, decorate your bag!

Utilise your permenant marker (washable markers will wash right off) to draw a sky in the upper half of your plastic bag.  Include clouds and the sunday, as they are important elements to the h2o bike.

Decorate your Plastic Bag with a Permenant Marker

Step 3: Prepare the H2o

Adjacent, fill a cup with regular tap water.  Then add a couple of drops of blue food coloring to information technology to make information technology stand up out.  Swirl the cup of water a few times to mix the coloring until information technology's a squeamish, solid blue.

Now, carefully cascade the water into the plastic pocketbook and zip it closed.  Make sure it's prissy and tight!  Y'all don't want any water to exist able to escape.

Pour the water into the bag

Step 4: Hang Upward the Purse

Once your water has been added to the bag and it'southward sealed up, it'southward time to hang information technology up on a window!  Pick a window that gets a lot of sunshine for best results.  Cut ii long pieces of tape and stick them to the corners of your pocketbook.  Then, press the record tightly to the window - y'all don't desire your bag to autumn downwardly!

Hang up your bag and observe the water cycle in action!

Footstep 5: Wait and Notice

Wait a couple of hours and cheque on your experiment.  You lot should encounter a change in your purse between ii hours and i day (depending on the amount of lord's day and the fourth dimension of day you started).

Somewhen, you will begin to see droplets of water sticking to the side of the bag.  Some of these will be upwards loftier (in the clouds) while other droplets will be on their way back down (like rain).

Why is this happening?  It'south because the water in the bag is being heated up confronting the sunny window.  That water turns into a gas through the process called evaporation.  In nature, evaporated water vapor goes into the atmosphere, but in our bag, it has nowhere to go, and so it ends upward sticking to the sides of the bag, turning back into a liquid as condensation.  That condensed water and so slides back into the pool of water below equally "rain".

Keep checking back on your experiment a few times a solar day, or someday information technology's sunny to come across the water bike progress!

With some uncomplicated materials and a weekend afternoon, you and your kids can accept a not bad time learning about the water cycle together.
