Light Colors and Plants Science Fair Project
Many plant functions can be enhanced and promoted just by knowing what light colors they react and respond to. Implementation of any Science Project Idea should be undertaken only in appropriate settings and with appropriate parental or other supervision. An excellent student experiment about color and heat absorption The following is documentation of a student's experiment with color and heat absorption. Make sure you are able to get at least one of the corners of cellophane up for watering later. And gosh - publish your findings here if you do perform the experiment.
The cells become differentiated into different organs and the mature cell maybe dead or living. The oxygen goes into the air and the hydrogen stays in the plant to help make sugar and starches. Plants react differently to different colors of light. Other spectrums seem to have very little effect in plant growth. Sunlight is a full spectrum of different wave lengths of light. Science Fair Projects - Do different colors of light affect plants differently? Red light has the longest wavelength, is the warmest, and is closest to infrared light.

The same thing was true for violet, indigo, and forest green fabric. And each color may play a unique role in the growth process of plants. Plants require sunlight to grow, which they transform into usable energy in their chlorophyll. Regardless how humans may react when showered with sunshine, it may be helpful for the serious gardener to know: how does light affect plant growth? By using this 4-stage spectrum control approach you can truly optimize the cosmetics, fragrance, density, and color, i. An adult can help saw the wood into 1 foot long pieces for you to use or the hardware store can do it for you. Plant leaves usually look green to us because they are reflecting the green back. There are lists that give the values of emissivity of various materials - in books on spacecraft design, thermal properties handbooks, and similar texts.
Hypothesis: The color blue would make plants grow the tallest. The energy from the light is what chops up the water molecules like your favorite horror movie villain. Chloroplasts are complex green structures within a plant cell that contains chlorophyll pigments and gives plants their green color. Measure 13605 grams of soil by measuring the weight of each plant in pounds, and converting it into grams. Light from the sun refracting through raindrops allows us the rare and beautiful glimpse of Roy G.

Dependent variable How will the dependent variable be changed? Regardless of whether the color of the light is red or purple the plant will absorb some amount of energy from the light it is receiving. Place sound-proofing materials in between each box. Research indicates that light can affect plant growth. Based on your knowledge of lights and plants, do you think this is the appropriate light for my situation? I suggest you read some of his work. Conclusion So in conclusion, it can not be stressed enough that these recommendations are only starting points, because the all the results are strain specific and can also vary with other factors such as temperature, shading, and nutrients. These wavelengths encourage stem growth, flowering and fruit production, and chlorophyll production. The green light will hinder plant growth as plants naturally reflect green wavelengths of light and therefore, the plants absorb absolutely no light.
Plants use other colors of light to fulfill basic needs of their life cycle. You might also be interested in. Cover each hole with soil. Phosphate Affect the Growth of Aquatic Plants? The process of photosynthesis is in green plants, algae and a limited amount of bacteria. Springfield, New Jersey: Enslow Publishers, Inc. We used red, blue, normal classroom lighting and no lighting for lab.
Cellophane tents don't work because they don't supply the correct amount and cellophane affects opaqueness of the light. The experiment itself can be extended to enable pupils to develop their ideas about collecting evidence in science and their investigative skills. Place one of the white light beakers upright into a large waterproof 2-liter beaker. Plants absorb light that they use to grow and to produce flowers, fruits and seeds. Elodea grows up to 3. Light is one of the most essential things used by plants to manufacture food for growth. Continue watering plants for four to six weeks.
Can you suggest any improvements or ideas? There are two types of chlorophyll, chlorophyll a and chlorophyll b, that each absorb different wavelengths of light and work together to give the plant energy to use to make food. Any conditions that harm such a balanced environment can potentially destroy thousands of organisms that live there. However, there are some species of plants that have non-green leaves year round. However, we used sugar dough cookie mix and mixed 7 different colors for 10 classmates to try. Yellow and blue are the worst for the growth of Dwarf French marigold plants. I picked the colors for my experiment, by asking myself some questions.
You can also do this experiment on several different types of houseplants to see if some plants respond faster or slower than others. How do plants absorb different wavelengths of light? The best light and the best nutrients will not effect yield as much as insuring that only flowers sites and select sun leaves see light, and that all flowers left on the plant get enough light. I measured overall height and leaf width for the tallest and best plant of each color. Repeat step 1 ten times 3. I suspect it's not the color 'temperatures' you'll find to be central, but the frequencies of light that come in contact with the plants. Without them, much of the world would be different and it would affect the planet in a negative manner. Materials: All the materials for this project are available locally.
Other plants might not like such a long sunbath and end up seeking shade back under the soil. They let 100 students try the three sodas and asked which they liked the best. Light is electromagnetic radiation that comes in waves, the basic units of which are called photons. Sunlight contains many different wavelengths which, when isolated, present different colors of visible light. Plants need to continuously make the chlorophyll in their leaves in response to light. Make sure the plants are watered and put in the sunlight all the plants must be put together 2.
