Visualizing scientific concepts leverages dual coding theory, combining images with words. Observing the cycle in action helps solidify abstract ideas about water movement and its phases.
1. Gather a clear ziplock bag and permanent markers. 2. Draw the sun, clouds, and rain on one side of the bag. 3. Fill the bag with about 1/4 cup of water and seal it tightly. 4. Tape the bag to a sunny window to catch sunlight. 5. Observe the changes over the next few hours — look for droplets forming! 6. Discuss with your family how this mini model relates to nature's water cycle.
