How Does Acid Rain Affect a Building?

Overview

Objectives/Goals To conduct my investigation, I will use multiple liquids (acids, bases, and neutrals) to simulate rain. The liquids will represent the independent variable as it will be changed. I will use a common brick to represent a building#s stereotypical exterior. The brick will be my dependant variable. Investigative question: How does acid rain affect a building? I hope to answer a few questions with this experiment: 1 Does acid rain erode buildings? 2 If so, how does it erode a building? 3 Does an acid erode faster? 4 Does a base help preserve buildings? Methods/Materials MATERIALS: 1 Stds bricks 10; 2 Med droppers 5; 3 Containers 5 - 20 oz; 4 Bleach 16 oz ea. liquid; 5 Milk; 6 Water; 7 Coke; 8 Vinegar; 9 Planter to house bricks. PROCEDURES 1. Place bricks in planter vertically. 2. Fill ea glass w/ ea liquid. 3. Place 3 drops on brick to start. Add 3 drops on the next day (adding 3 more drops to amount ea. day). 4. Observe for 15 days. 5. Tally up your observations. 6. Chart how each liquid did using a point system. Point System for effect & discoloration: 1st=5pts, 2nd=4pts, 3rd=3pts, 4th=2pts, 5th=1pt. Add up pts & make final rankings. Convert rankings into chart.
