Earth: Water Cycle

Water Cycle

Welcome to another Playful Preschool Wednesday post. This is were a group of bloggers come together to share some free hands on learning activities for preschool aged children. Last week we explored Space and this week we are exploring the Earth with an easy preschool science experiment.

My girls and I had fun last week exploring earth. We focused mainly on the workings of our planet. While I thought our activity of showing how earthquakes happen was going to be a hit it turned out to be a dud. What did turn out great is our water cycle in our window. This was something the the girls checked daily and multiple  times a day. Next time we do this we will be better at recording.

The purpose of this activity was to show how the earth recycles water. The lesson that we learned  is that if our planet can recycle  then so can we. (We already recycle. My preschooler just caught  on to the earth’s recycling)

We made an water cycle bag for our window. The idea is to let the bag sit in the window (we picked the window that gets the most sun) and let the sun warm the water in the bottom of the bag so that the fun can begin.

Water Cycle


For this activity  we used: 

  • One sandwich sized zip lock bag
  • Blue marker
  • Yellow marker
  • Black marker
  • Tape water


  1. Draw a sun in the top corner of the bag with the yellow marker.
  2. Use the black marker to draw a cloud in the opposite top corner of the bag
  3. Use the blue marker to draw a water wave 1-2 inches above the bottom of the bag.
  4. Using the blue marker again draw on some raindrops (I did this after a day or so per the suggestion of my two year old.)
  5. Add your water up to the water wave line
  6. Seal bag and tape to sunny window

For our records we took a picture of the bag daily and the girls both checked it daily. Heck they checked it at least three times a day. Once in the morning when we woke up, in the afternoon once the sun had finally hit it’s high point, and at night right before bed.


What did we notice


  • Cold looking water bag with small droplets of water above the water wave line. It was always a misty morning in the bag.


  • On a hot day we got some small water droplets from above the water wave line to the top of the bag.
  • On a cooler day nothing changed from the morning look


  • The water settled and sometimes we could see little droplets sometimes we couldn’t

Different  weather

  • On the days that it was foggy we noticed that the water had not changed.
  • On the days that it was hot we had a nice wet bag with big bead drops of water
  • On the cold day we had last week that bag was misty and wet.

New words that we learned this time were:

Condensation and precipitation.


Water Cycle

We are enjoying watching the water tell the weather in the house. I can’t take it down yet because  it has not gotten  hot enough for the girls to really see what will happen. They want to wait until the end of summer.

By day four of this experiment our drawing was gone. I suppose it was due to the constant weather change or the blinds being let up and down so often.

Well that’s it for today. I hope that you enjoyed this post and if you would  like to see more activities  then check out the posts below shared by the Playful Preschool  Team.

    Fantastic idea – I know what we will be setting up for the summer months here when it’s warm enough for the full cycle to work.

    What a fun experiment! This would be great for multi-aged homeschoolers since each child could explore according to their skills!

  7. We have had lots of rain lately so that has brought up lots of questions about where water comes. This activity is super helpful.

      yeah we had lots of questions about the rain also. Great for me because I love the rain and can tell them more about rain than I can anything else.

  8. Thanks for the great idea / resource! I have water cycles for later in the year and this will be perfect
