I need to do a biology research project. Basically it calls for conducting a set experiment and recording the data and information. But I don't know what to do. Like some ideas are growing a fern, one with fertilizer, one w/o, or seeing the variation in fruit flies offspring and recording that shit, but that has been done and I need to think of something new. Anybody with any ideas?

In this science project, you'll use food dyes to follow the path of water through a carnation.

All plants, even those living in deserts, need water to survive. Plants use water to keep their roots, stems, leaves, and flowers healthy and to prevent them from drying out and wilting. The water is also used to carry dissolved nutrients throughout the plant.

Most of the time, plants get their water from the ground. This means that the plant has to transport the water from its roots up throughout the rest of the plant. How does it do this? Water moves through the plant by means of capillary action. Capillary action occurs when the forces binding a liquid together (cohesion and surface tension) and the forces attracting that bound liquid to another surface (adhesion) are greater than the force of gravity.

A simple way of observing this is to take a teaspoon of water and gently pour it in a pool on a countertop. You'll notice that the water stays together in the pool, rather than flattening out across the countertop. This happens because of cohesion and surface tension. Cohesion is the attractive force that pulls similar substances together. In this case, the individual water droplets are being pulled together. The force of the pull is strongest at the edge of the pool. The water droplets at the edge have fewer neighboring water droplets, so they cling more tightly to those around them; this is known as surface tension. Now gently dip the corner of a paper towel in the pool of water. The water is attracted to the paper and "climbs" up the paper towel-this is capillary action.

Materials and Equipment

For this science project, you will need to gather the following items:

* Water (1/2 C.)
* Measuring cup
* Glass or plastic cup
* Blue or red food dye
* Spoon
* Several white carnations (minimum of 3)
* Knife (ask an adult for help with the knife)
* Camera (optional)



* Camera (optional)

Experimental Procedure

1. Measure out 1/2 cup of water.
2. Pour the water into a glass.
3. Add 20 drops of food dye to the water in the glass. Stir with a spoon until the dye has fully dissolved in the water.
4. With the help of an adult, use a knife to cut the stems of several (at least three) white carnations at a 45° angle. Be sure not to use scissors, as they will crush the stems, reducing their ability to absorb the water.
5. Place the carnations in the colored water.

Observe your project 2, 4, 24, 48, and 72 hours after you first put the carnations in the colored water. Write down what you see in a data table like the one below. Don't forget to record what the flowers look like at the beginning of the project! You can also draw pictures or take photos of the flowers at each time interval.

Variations

Here are some additional questions you can investigate with this science project.

* Do you see the same results with other flowers and plants? How about trying another white flower, like a daisy? Or try a plant that is mostly stem, like a stalk of celery.
* What are the results if you use other colors of food dyes? Is the effect easier or harder to see?
* What happens if you increase or decrease the concentration of food dye in the water? Try using one-half, twice, four times, and ten times as much food dye.
* How would you make a multi-colored carnation? Hint: Two methods to try are:
Leaving the flower for a day in one color of water and then putting it in another color of water for a second day
Splitting the stem in two and putting each half of the stem in a different color of water

That's a good website. I'm not going to do this project, but that site is filled with them. thanks Zombie Terri Schiavo/Mouse. The site fits the bill i think.

Cum in an underwear and then Cum another one in something made from another material and record which becomes crusty the fastest

Or you can just save us the time and tell us. :wakeup
