1. Does iron rust more quickly in Mott's apple juice, Ice Mountain water, salt water, or Coke?
For this experiment, I will be trying to prove which liquids rust iron the quickest. To do this experiment, I will get 16 tablespoons of each liquid. I will then get four clear containers and put a label with the correct liquid name. Next, I will put the correct liquid in the correct container. I will put the iron nails in each container and watch them rust. I will put my information in a data table. After one of the nails rust, that liquid is the winner.

2. What detergent removes stains the best?
For this experiment, I will be trying to prove that one detergent will be the best for getting out stains. To do this, I will get three different detergent. I will also get the same number of shirts, which will be fifteen because there will be four loads of laundry to do so I should have a few extra shirts. I will be getting fifteen because if one of the shirts does not work well, I have other shirts to test out. They will all be the same color, same size, and same brand. I will stain each shirt with the same thing and wash four shirts with one detergent and another four shirts with the other detergent and so on. I will do it this way to see which detergent works well on getting stains out.

3. Do LED lights or regular lights help plants grow better?
For this experiment, I am trying to prove which type of light helps plants grow better. To determine this, I will get get two the same plants and put them in the same pots. I will also give it the same amount of water. I would get two lamps but put a regular light bulb in one and an LED light bulb in the other lamp. I will record how tall they get over a period of three days and see which lamp works the best.
