how does different color light affect plant growth experiment

My second hypothesis was that green light will produced the least oxygen. My second hypothesis is that elodea will produce the least amount of oxygen when in green light. From: The Independent variable of this experiment is the light that enter the plant. It can inhibit growth, reproduction, and plant health. Below are some general strategies and recommendations based on years of practical experiments with indoor lighting.

Question: I need help with an experiment I'm doing. This evolved in bacteria long before the appearance of more complex leafy plants. Links to More Science Projects Here's a compilation of all the pages with information from students who are conducting scientific color experiments. For your experiments, I suggest using distilled water to eliminate the possibility that heat or light frequency is affecting some component of your tap water. I measured overall height and leaf width for the tallest and best plant of each color. Place the three boxes on a table. To answer your question though, yes, light affects plants.

Can Colored Lights Affect How Plants Grow?

how does different color light affect plant growth experiment

Background information: The relationship between light and plant growth can be demonstrated by exposing leaves to various colors of light. Purpose To determine whether different colors of light hinder or aid in the growth of common bean plants. The colors used in the experiment are red and green. Dependent variable How will the dependent variable be changed? This has produced a very detailed map of which light spectrum is related to which type of plant growth. Hold the graduated cylinder in place with a ring stand clamp. Elodea grows up to 3.

Try this experiment on a non-green leafy plant it may need to be an outdoor plant, which is okay. If you use a prism, you can separate the white light into the colors. The cells become differentiated into different organs and the mature cell maybe dead or living. Be sure to measure from the bottom of the aquarium and not the surface of the potting soil. If the intensity is 6. Cover each hole with soil.

Is Plant Growth Affected by Light Color?

Fill each of the plastic cups ¾ full with potting soil and plant each seed ½ inch deep in the soil. The information gained from this experiment can be used in green houses to determine under which color light do plants produce the most oxygen. How does the health of the plant change depending upon the number of leaves blocked from the sun? Because this is the main way in which plants obtain their food, and light energy is the base of said process, light is absolutely essential for their growth. What may be news to you, however, is that the color of the light has a measurable impact on the amount of energy a plant absorbs. As an aside, the typical cool white fluorescent lamp emits strongly in the blue and green emission bands try peeking at one with a prism or spectra scope. It may even make our featured science project! The color of light measures its quality.

Can Colored Lights Affect How Plants Grow?

how does different color light affect plant growth experiment

Potency is important and often tested but typically considered strain specific and not considered that dependent on cultivation techniques. You may not be any warmer if you wear blue instead of green, or green instead of purple. Light is one of the most essential things used by plants to manufacture food for growth. We used red, blue, normal classroom lighting and no lighting for lab. Welsh and Cotner, 2012 They do that by converting light energy into chemical materials, and plants are the only organisms capable of carrying out that process. Good luck with your experiments. Apply the recommended dosage of fertilizer.

Light Spectrum and Plant Growth

how does different color light affect plant growth experiment

Plants absorb light to harness its energy for plant growth and internal processes. Light traveling in a wave has a wavelength, which is a measure of the cycles of the wave. But that is just one of the factors to consider when it comes to lighting. To cultivate them, you will need soil, water, light, oxygen, the right temperature, and the mineral nutrients they need to grow. Abstract The objective: My objective is to find out how different light colors affect plant growth. Anonymous: About the absorption of heat and emissivity in coffee cups: The cups would take heat energy from the coffee at same rate, given same material of cup, as this is conductive heat transfer, while the white cup will radiate heat to surrounding air more slowly than the black cup, and so in total the black cup of coffee will cool down quicker. Many plant functions can be enhanced and promoted just by knowing what light colors they react and respond to.

How Color of Light Affects Plant Growth

how does different color light affect plant growth experiment

These catch the light to be used in photosynthesis. Repeat the experiment at least 6 times and calculate the average temperatures for each color. It is only through refraction of light that the many wavelengths of light are reflected to show different colors. Plants use light to turn carbon dioxide into sugars necessary for growth, a process called photosynthesis. What would you tell our sponsors about how Science Buddies helped you with your project?
