Acid rain experiment request
Name: Tess Troha-Thompson
What is a good science experiment to demonstrate acid rain?
Plant five or ten beans. Water the first with pure water, the second with a
little lemon juice in the water, the third with a little more lemon juice, and
so on, until the last plant is getting pure lemon juice. Lemon juice is
acidic, like acid rain (that is why it tastes sour). Observe how the beans
grow, measure their height every week, and write down the color.
Which beans grow best?
