I am having a science fair on 12-9-09.My project is if the color of light affects the growth of plants. The people who i am working with Kylan and Charles we are going to work on it this Saturday i hope we win! The science fair is going to be in the gym.The suply we have is 1 green bottle and 1 clean bottle. I got that project cause my buddies picked it.We are going to Kylans to finish it.

To grow most plants need water air nutrients from soil or water and light.plants get their energy directly from light. During a process called photosynthesis they use light and energy to manufactrue simple sugars from water and carbon dioxide. Without light most plants would die.But not all light is created equally.Sunlight which most plants rely on is a full-spectrum light source. It consists of a wide range of different wavelengths when you look at a rainbow.other light sources such as incandescent.

Or fluorescent bulbs frequently are missing some wavelengths of light.As a result indoor plants that get their energy from an artificial lamp or from sunlight passing through a tinted window which filters out certain wavelenghths are often stunted.In this activity you are going to investgate if the color of light affects a plants growth.You will need about two weeks to complete your observations.Place your two plant samples side by side on a sunny windowsill or under a grow lamp.

Use the maker to laber one pot green and the other clear. Carefully observe the two plants.Use the ruler to measure the height of each plant and the width of its leaves.Record your observations for each plant below. Water each plant with the same amount of water.You will be conducting a controlled experiment which means that all conditions for both plants will be the same except for one. Why is it important for the two plants to be as similar as possible in every way?Cover the plant labeled green with the green soda bottle cylinder and the plant labeled clear with the clear soda bottle cylinder.Leave the caps off the bottles.Check the plants each day over a 14 day period remembering to water them every few days so they dont dry out.Record your observations below.
