The Expirment:
This expirement is going to state what happens tp shells and coral when effected by acid rain.

Let's Start:
The following are the steps in which you will take during this project. Read the items listed below.

Hypothesis:
List your predictions on what this experiment is going to prove and disprove.
Materials:
List the materials that you are needed for the exepriment. Remember to be specific.

Procedure:
List the steps in witch you took to preform this project.

Observations:
Write down what you have noticed during the process of the experiment.

Materials Needed:
  • 3 empty Soda Bottles
  • pH strips
  • Lemon juice
  • Water
  • Measueing Cup
  • Paper
  • tape
  • Permanent Marker

Before you Start:
  1. Label each bottle: 1, 2, 3, with paper, and attach it with tape on the top and bottom,
  2. Leave room in the upper left hand corner, this is where you are going to put your pH readings.
  3. To research on pH readings, see: pH Scale .
  4. Make sure that you understand the pH scale before you start, this scale will be used later in our experiment.
5. This expirement will take 3 days, so remember to refigerate your mixtures.

Start your Experiment:

  1. Pour a small ammount of lemon juice into the measuring cup. Then dilute the juice with a small ammount of water.
  2. Then, test the pH scale with the pH strips.
  3. Make sure that the mixture is not heivily acidic.
  4. Write the measurement on Bottle 1 (while looking at the link above) in the space you left on the peice of paper.
  5. Using the spout of the measuring cup, pour the mixture into Bottle 1.
  6. Do the same thing for the other 2 bottles. but remember that Bottle 3 has the most acidic out of all the bottles. Bottle 2 will be in the middle pH of the 3.

Record Your Data:
Remember to take good notes during this project.
