In this experiment, we will explore patterns of acidity in rain water.
- Several rainy days
- pH paper with chart indicator
- Standard beakers
- Pen/paper for notes
- On a rainy day, take a beaker outside and allow it to fill up with water. About ¾ full would do the trick.
- Come back inside and dip the strip of Ph paper in the water. Take the strip out, note the color and compare it on the color guide to find out the Ph. Record this number.
- Repeat steps 1-2 for at least seven rainy days. Did you notice an differences in Ph or is it exactly the same?
- Evaluate your results.
