Procedures for my bean expeirment.

                                                                               Original methodology                                
Step 1: Get materials.
Step 2: Fill cups with 3/4 of the way full of dirt.
Step 3: Put the seeds in the 2 cups.
Step 4: Fill one cup with 5 ML full of water.
Step 5: Fill the other cup with 5ML full of Dr. Pepper.
Step 6: Do steps 4 and 5 each day for 3 weeks.
Step 7: Record your data regularly basis each day by how tall its getting.
Step 8: Which liquid made it grow faster? (conclusion)
                                                        Revised methodology
Step 1: Make a hypothesis/ What will make the seed grow faster Dr.Pepper or water?
Step 2: Get the materials needed.
Step 3: Get 2 beans that have the same color and texture.
Step 4: Get 2 cups and fill them 3/4 of the way full of dirt.
Step 5: Weigh the beans and get two that weigh the same. Also weigh the dirt and make its weight equal for both cups.
Step 6: Dig a hole in the middle of each cup 2 centimeters into the cup.
Step 7: Place 1 seed in each cup, and then fill in the hole.
Step 8: Fill 1 cup with 5ML of water, and the other 5ML full of Dr.Pepper.
Step 9: Make a table and measure the size it has grown each day for 3 weeks.
Step 10: Conclude your data by which has gotten taller.

            I had to change my procedure because, if I had to do this by my first procedure there might be parts missing and I wouldn't be able to figure it out so I made a revised copy so its easier to get it done. In my last procedure I didn't say to weigh anything or get a very similar bean. I also didn't say how far to dig the holes in the dirt to bury the seeds.
