For our planting we have two quads. One is controlled. Controlled is one where nothing changes. All of it is the same. The other quad is called manipulated. Manipulated is a quad where you change one thing. You only change one thing because if we changed more than one thing then if the plant does not grow you won’t know which thing that you changed did the damage to the plant or if both things you decided to manipulate caused the damage to your plant.
How we set up each caud was like this. First we put in a wick to absorb water, acting like a root so it can give water to the plant. Next we added a little bit of soil about half way up. After that we put in three fertilizer pellets. Then we put in more soil over it. After that we put the seeds in. We poked a hole in the soil with our finger. Then we put in two and seeds and now two plants are growing in each quad. After that we had to cover it up and then our plant was ready!
We have been doing this for seven days. I have noticed a lot in the seven days. On the first day nothing much happened. There was just a little plant on the quad that was around a mm high. For the next six days the plant was a lot bigger and now it is around five cm! It is like a person growing into a adult. Around day four it started to grow very high. Then day five came and it was crazy if you think that it grew that much in three days! Now on day seven the plant is about six cm high!
Now since you change only one thing we don’t see much of a change in our plant. My group decided to water the plant with food coloring instead of water. We have been manipulating it for two days so right now our plants are a little droopy. We each had a hypothesis. My hypothesis was if we add food coloring to the plant, then it will still grow, because food coloring has water in it. Also my group is wondering if the plant will turn a little bit red because we used red food coloring and we put it in the soil so it might go under the plant to the roots and the roots might turn a little red and cause the plant to turn a little red.
