The effects of acid rain to erode marble structures
Abstract: The purpose of the experiment is to measure the concentration of the ethanol made during the yeast fermentation with sugar. Results during the experiment showed the more yeast placed in the container, that the concentration increased. The most significant point of discussion was the amount of time the experiment took. Also, how the experiment can be made to go faster, that yeast have much of the same qualities humans have. The

We are looking for the concentration of the ethanol to water. To determine if the amount of yeast increase if it will affect the concentration of the ethanol.

Hypothesis: If the amount of yeast increase, then the concentration of solution will also increase. I predict that the more yeast there is that the sugar will also be affected by the concentration increasing. My hypothesis means that if there is more yeast put into that the solution will increase This is your prediction of the effect one variable will have on another.
-What you think will happen/your predicted answer
-Justify your hypothesis
-Future tense
- e.g. If the concentration of acid increases, then the rate of marble breakdown will increase.

Equipment: List the equipment you need to conduct the experiment in alphabetical order. Draw a labeled diagram clearly showing what the equipment is and how it is used, preferably large and easy to understand.
