Water Cycle

Look right in front of you.  Do you see that?  Yes, right there all around you.  It's water vapor!  
Our water cycle board
1st graders have been hard at work learning about the water cycle.  We began by making our own water cycle board in our classroom. We made sure to label the important vocabulary: evaporationprecipitation, and condensation.  After we finished our introduction to the water cycle we transformed into scientists and began a water cycle experiment.  

 Students were paired up to construct their Mr. Potato head inspired water cup for our experiment.  Cups were filled with water and placed around the classroom.  Some experiment cups have nothing on top of them, other have napkins, tissue paper, duct tape and even plastic bags (some with holes).  We need lots of variables for a good scientific experiment.
Once experiment cups were filled with water, students worked as pairs to make a hypothesis about what they predict will happen to the water in their cup. 1st graders wrote their hypothesis in their water cycle journal.  
Now we wait and observe what happens...


  1. The science book our district uses has a basic evaporation experiment using two jars (one covered and one not) -- your experiment is cooperative and much more hands on. Thank you. -- Nelcy

    1. I'm so glad you enjoy the experiment. It's always a great experiment and a huge hit with the students! Happy Evaporation :)
