This is blog post 2. I am going to update you with the measurements of the plants over the last 2 to 3 weeks. These are the very important updates.

On June 1st the highest the controlled plant had grown was 8 cm in cell 2. By June 5th the highest the controlled plant was 14 cm in cell 3. The plants now have buds and some of the buds have bloomed into yellow flowers.

On June 1st the highest manipulated plant was 12 cm. It has grown really tall. We have been watering the manipulated plants with red food coloring. One of the cells has a little speck of red on the plant stem. The manipulated plants have two flowers, the same as the controlled plants.

We have noticed that the manipulated plants are a little bit shorter than the controlled plants. They have the same number of flowers, and the flowers are both yellow. I think the manipulated plants are a little shorter because they are adjusting to the food coloring.

 In class we are studying a plant unit in science.  When we started to plant we put wicks into each cell.  We have wicks so when we have no school they can suck up water from the felt and give it to the plants. Then we put some dirt in the cells half way up.  Then we put in 3 fertilizer pellets then we added more soil. We used an index finger to make a hole in the dirt. We put 2 seeds in each cell. We then covered up each cell with more soil to the top.  

We have two quads, one is controlled and one is manipulated. The controlled is everything stays the same, we don’t change anything.  We are giving the controlled 5 drops of water, same amount of sunlight using the plant light, same soil, fertilizer, and 2 seeds. On day 3 the plant started growing and it was 1 cm.  On day 3 there was 4 leaves and it was green. On day 7 in cell 1 it is 3cm . The highest plant is 4cm in cell 2 and has 4 leaves.

On day 6 we added 1 variable which was red food coloring. We are following the scientific method. Our scientific question is what is the effect of altered water on plant growth?  Our hypothesis is if I add food coloring then I think it will still grow because the water is just a different color. I also wonder if the plant turns red.
