Product Description
Acid rain is a term used generically to describe any type of
acidic moisture, be it rain, snow, or fog. Acid rain can have
devastating effects on not only aquatic ecosystems but also
terrestrial areas. Acid rain not only effects naturally-occurring
surfaces, such as exposed rocky surfaces of mountainous
regions, but also human-made surfaces as well. Different
stone and metal substances used in the construction of
buildings, statues, monuments, etc. may all be affected by
acid rain. The rates of erosion and weathering may increase
rapidly depending on the degree of acidity in the precipitation.
In this activity, students expose many rock materials and
metals, both naturally-occurring and common in construction,
to an acidic environment and examine the reaction of
these materials in contrast to the same materials exposed
to “normal†rain (tap water). There are enough materials for
15 groups. Teacher’s manual and student copymasters are
included.
