 1. Choosing A Project:  TOPICS THAT INTEREST ME: CURRICULUM CONNECTION  :  • When you put a white flower in water that has food coloring in it the flower changes color so if you water a potted white flower with colored water will it change colors? • Is it possible to make a gravity free chamber and if so what would its affect most likely have on objects. •How long dose it take to teach a 5-year-old boy to read? •What is the farthest distance I can make a catapult fling an object? MY TESTABLE QUESTION:  • When you put a white flower in water that has food coloring in it the flower changes color so if you water a potted white flower with colored water will it change colors?- Plant cells. INDEPENDENT VARIABLE:color of water  DEPENDENT VARIABLE:the flower  What about the flower??? 2. Investigate the Information: ﻿  NOTES/FACTS:  Food dye in the water of a vase changes the flowers color. The flower drinks the colored water and as the water traveled up the stem and into the petals, it carries the food coloring with it. As the food coloring reach the petals, they take on the color of the water. Incidentally, this is similar to why flamingos are pink. Flamingos eat a lot of shrimp and shellfish and they absorb the pink and red colors into their feathers, making them pink. one web site said that it was possible to change the color of plants trough change of pH or by changing genes in a lab. The color changes through plant transport. The plant absorbs the colored water through the tissues in its stem, which pulls the water through the plant by forming a hydrogen bond with the water molecules. This hydrogen bond creates a string of water molecules that travel up the stem and out to the leaves and flowers of the plant. In this case, the colored water is dispersed in the outermost tips of the petals and leaves, where transpiration occurs. : http://wiki.answers.com/Q/How_do_flowers_change_colors_with_food_coloring#ixzz1HFnu9NDb  How the Eye Sees Color;  Color originates in light. Sunlight, as we perceive it, is colorless. In reality, a rainbow is testimony to the fact that all the colors of the spectrum are present in white light. As illustrated in the diagram below, light goes from the source (the sun) to the object (the apple), and finally to the detector (the eye and brain). 1. All the" invisible" colors of sunlight shine on the apple. 2. The surface of a red apple absorbs all the colored light rays, except for those corresponding to red, and reflects this color to the human eye. 3. The eye receives the reflected red light and sends a message to the brain. The most technically accurate definition of color is: "Color is the visual effect that is caused by the spectral composition of the light emitted, transmitted, or reflected by objects.  http://www.colormatters.com/seecolor.html  When the sun's rays refract light through millions of raindrops, a colored arc appears in the horizon, better known as a rainbow. Most people have never noticed that the sun is always behind you when you face a rainbow, and that the center of the circular arc of the rainbow is in the direction opposite to that of the sun. The rain, of course, is in the direction of the rainbow.  We will discuss the formation of a rainbow by raindrops. It is a problem in optics that was first clearly discussed by Rene Descartes in 1637. An interesting historical account of this is to be found in Carl Boyer's book, The Rainbow From Myth to Mathematics. Descartes simplified the study of the rainbow by reducing it to a study of one water droplet and how it interacts with light falling upon it. He writes:” Considering that this bow appears not only in the sky, but also in the air near us, whenever there are drops of water illuminated by the sun, as we can see in certain fountains, I readily decided that it arose only from the way in which the rays of light act on these drops and pass from them to our eyes. Further, knowing that the drops are round, as has been formerly proved, and seeing that whether they are larger or smaller, the appearance of the bow is not changed in any way, I had the idea of making a very large one, so that I could examine it better. Descartes describes how he held up a large sphere in the sunlight and looked at the sunlight reflected in it. He wrote, "I found that if the sunlight came, for example, from the part of the sky which is marked AFZ and my eye was at the point E, when I put the globe in position BCD, its part D appeared all red, and much more brilliant than the rest of it; and that whether I approached it or receded from it, or put it on my right or my left, or even turned it round about my head, provided that the line DE always made an angle of about forty-two degrees with the line EM, which we are to think of as drawn from the center of the sun to the eye, the part D appeared always similarly red; but that as soon as I made this angle DEM even a little larger, the red color disappeared; and if I made the angle a little smaller, the color did not disappear all at once, but divided itself first as if into two parts, less brilliant, and in which I could see yellow, blue, and other colors ... When I examined more particularly, in the globe BCD, what it was which made the part D appear red, I found that it was the rays of the sun which, coming from A to B, bend on entering the water at the point B, and to pass to C, where they are reflected to D, and bending there again as they pass out of the water, proceed to the point ". http://eo.ucar.edu/rainbows/ Many people are familiar with the concept of dyeing flowers with food coloring. But did you ever stop to think about the underlying process that occurs when you dye flowers using just colored water? The structure of the plant and natural processes like transpiration and cohesion enable many flowers to readily absorb the food coloring and deposit the dye on their petals.

Two processes occur in a plant to help it absorb water: capillary action and transpiration. Flowers absorb water through the xylem, a tissue of thin tubes found on the outer stem of plants. Its job  is to transport water and nutrients from the roots to all areas of the plant. The water moves up the xylem like soda moving up a straw when you suck on it. This process is called capillary action. The water molecules are attracted to the molecules in the xylem, helping to pull the water upward. Solar energy also pulls the water up through the plant. Sunlight evaporates the water from the surface. This transportation process of water is called transpiration. The top of the xylem tubes become empty from the loss of water, creating a vacuum, so water rises to fill the empty space.

A plant's stems contain passageways that allow water to travel  from its roots to its leaves and flowers. Adding food coloring to the water illustrates the path it takes on its journey to the flowers, where it eventually deposits its pigments. How It Works Water molecules pass directly through the walls of the plant's hair-like roots and immediately make their way up through the xylem, or the tiny pipelines that run the length of its stem. In this way, colored water travels  to the plant's leaves and stems and is stored briefly in tiny pores called stomata. Plant Plumbing In a system of water displacement, water that moves up into plant through its roots replaces what is lost through transpiration, or the giving off of water into the atmosphere. As colored water reaches the plant's flowers, the water is released by the stomata but the coloring remains in the petals and along some of the leaf veins. Cutting the plant's stem also reveals food coloring around the edges of the xylem. Effects Tinting plants with food coloring works best on plants with pale or white flowers, such as Queen Anne's Lace or white carnations. According to the MadSci Network, red or blue coloring works best, and it takes about six to 12 hours for a white flower to show the full effects of the food coloring.
