The best way to color fresh flowers is to cut the ends, and place in containers of water that have food coloring in them.  The stems will absorb the colored water, and eventually change the flower color.  The longer they are in the water, the deeper the color will be.

Grind the leaves with sharp sand and ethanol in a pestle and mortar.\nThe solution will contain many pigments - mostly those associated with photosynthesis.\nA fine mesh filter is usually sufficient to retain the sand and debris.\nSeparate the pigments by chromatography.\nNote: extracted pigments are light sensitive and will degrade.

You can dye yarn using several different methods.  For wool, alpaca, angora, nylon, and other natural protein fiber yarns (not cotton) you can use what is called acid dye.  The acid dye can be anything from comercially purchased dye (I use Jacquard acid dyes) to Kool-Aid (Kool-Aid really works!  Very well!).  \n\nThe "acid" part of the name comes from the fact that you need to use an acid to "set" the dye into the yarn so it doesn't wash out.  You can use a chemical mordant as your acid, or something safer like vinegar or citric acid to set your dyes.\n\nThere are several different methods of dyeing the yarn but here's how I do it.  First, soak the yarn in some hot water for about 30 minutes.  This will help the yarn take the dye.\n\nMix your dyes in small containers according to the instructions that came with your dye.  Generally you add a small amount of dye, water, and a couple tablespoons of vinegar.  Next, lay your yarn out on some plastic wrap, and pour small amounts of of your dye onto the yarn.  This is called handpainting the yarn.\n\nWhen you are done, roll the yarn up in the plastic wrap and microwave it on high.  Check it every few minutes, watching for the colour of the water on the yarn to turn clear.  This means the dye has exhausted and will not rinse out of your yarn when you wash it.  Rinse your yarn and hang it up to dry.  You've dyed yarn!\n\nThere are many other methods of dyeing yarn like crockpot dyeing, rainbow dyeing.  Try Googling how to dye yarn if you need more information.

MAKE A RAINBOW \n\nMATERIALS:\n\nglass of water \nsheet of white paper \nthe sun \nPROCESS:\n\nFill the glass all the way to the top with water.\n\nPut the glass of water on a table so that it is half on the table and half off of the table. Be careful that the glass doesn't fall.\n\nThen, make sure that the sun can shine through the glass of water.\n\nAfter you do that, place the white sheet of paper on the floor.\n\nAdjust the piece of white paper and the glass of water until a rainbow forms on the paper.\n\nEXPLANATION:\n\nWhy does this happen? Light is made up of a lot of colors. Specifically, the colors are red, orange, yellow, green, blue, indigo and violet. When light passes through the water, it is broken up into the colors seen in a rainbow.

Here are some fun and A+ ideas.\n\n1. Can solar energy be used to cook food? (You will build or buy a solar oven and see if it is possible to cook hot dogs. Simple and really is A+ material. Trust me, that's what I got on it!)\n\n2. What are all the microscopic things found on one strand of human hair? (Test a strand of your hair, someone else's hair and more under a microscope. Easy, simple, and informing.)\n\n3. What ingredients help plants grow? (Test different soil and items to see what makes plants grow the most affectively. Easy and fun.)

Hydroponic Nutrient Solutions\n\nThe macronutrients and micronutrients must be added to the hydroponic solution.  There are very complex recipes for making the hydroponic nutrient solution.  One of the most common and widely used is Hoagland's Nutrient Solution.  The following table gives all the chemicals used to make a Hoagland's nutrient solution:\n\nhttp://generalhorticulture.tamu.edu/YouthAdventureProgram/Hydroponics/Hydroponics.html\n\n\nIf you do not want to make your own nutrient solution, you can Google "hydroponic supplies" and you will find many web sites where you can order hydroponic nutrients that you just dissolve in water. \n\nHere's a few hydroponic vendor sites to get you started:\n\nhttp://www.hydroempire.com\nhttp://www.bghydro.com/\nhttp://homeharvest.com/\nhttp://www.hydroponics.net/items/\n\nBest of luck!

You will need to hit the library since such general information will require multiple books to explain.  If you have some specific questions, post those.  Just the dyeing part is a very complicated subject if you want details.  If you want some general starting points look at the links at \n\nhttp://www.itt.edu/staff/boyter/links/index.html#WASTEWATER

The pigments belong to a group of chemicals called flavonoids.\nPlants make all the things they need from carbon dioxide in the air and water from the soil (this is photosynthesis) plus minerals (e.g. nitrates, sulphates, phosphates, etc.)from the soil.\nThe pigment you mention and any other colour you see in plants is made by the plant.\nPlants make themselves.
