Puddle Science: Watch Evaporation in Action
The water cycle is a second grade science concept with some challenging elements: evaporation, condensation, and precipitation. While precipitation (rain, snow, and hail, for example) and condensation (water droplets collecting on a cold beverage glass, for example) can be seen with the human eye, evaporation is much less visible a process. So how can you make this challenging science concept more visible to your second grader? Try this activity, in which your budding scientist collects information about a puddle that seems to disappear before his very eyes!
What You Need:
- Sidewalk chalk, in various colors
- An outdoor puddle on a paved surface, such as a sidewalk (Important! Choose a puddle that is in a location where it is not likely to be disturbed.)
- A sunny day
- Colored pencils
