Plants appear green to us bec… Explore this fun middle school science fair idea to learn about photosynthesis and the key role of light in the growth of green plants. Office stores sell colored transparency sheets. Plants use sunlight to make energy. Light supplies the power to carry on photosynthesis, the food-making process in leaves… Thus, roses do not thrive in the shade whereas yews will grow quite well in a shady location. Therefore, while red light isn’t the most efficient color for general illumination for people, it is among the best colors of light to stimulate plant growth. Find more gardening information on Gardening Know How: Keep up to date with all that's happening in and around the garden. This science fair project idea researches the effects of acid rain on plant growth. Background: The relationship between light and plant growth can be demonstrated by exposing leaves to various colors of light. Plants affected by light shortages or too little blue light will have the following signs: Read more articles about Environmental Problems. this curve is sometimes over-interpreted, it does show that red light is at least as effective as other colors of light at promoting plant growth. Some plants require … Adequate spacing between plants will ensure that each plant receives sufficient light … Blue light is essential at the beginning of a plant’s growth cycle as this is the type of light that plants first absorb to help with chlorophyll production. Procedures: Plant four soybean plants of the same size in an aquarium containing 5" of well moistened potting soil. Plants absorb most light, but filter out the color they do not need. Normally they are referred to as low/shade, medium/part sun or high/full sun plants. Kids learn about greywater and how it affects plant growth in this cool science fair project. This hormone is responsible for the plant’s stem and root growth. The purple and blue light wavelengths, 400 to 490 nanometers, stimulate the vegetative growth phase while the yellow-orange-red wavelengths are used for flowering and fruiting. Wiggly worms are known for staying buried in the soil, but how does that affect plants? Keep in the same location during the experiment and water daily. Does The Color of Light Affect Plant Growth? All things need energy to grow. Other factors such as temperature and available soil nutrients are important, but without sunlight the plant cannot … Plant growth relies on a series of interactions that involve the presence of light. Plants see blue light as well as red light, using a photoreceptor that is called a cryptochrome. In this science fair project, students examine how the flow rate in a stream affects the growth of aquatic plants. of the plant. Green light is generally reflected away from plants (which is why they appear green), but plants will absorb a small amount of green light throughout the photosynthesis process. Thus the amount of sunlight a plant receives will effect its rate and amount of growth. Blue and red light, which plants absorb, have the greatest effect on plant growth. Light quality is the color or wavelength that reaches the surface of the plant. Plants get energy from light through a process called photosynthesis. The natural spectrum of color in a ray of light includes all the colors of the rainbow, but only two are ultimately necessary for plant growth--red and blue. For example, leaves appear green because green is the color most leaves reflect rather than absorb and use. How do Culverts Affect Plant Growth in Streams? This science project examines the effect of culverts on plant growth in streams. Purpose: The purpose of this project is to show that different colors of light affect the development of plants. When determining the effect of light on plant growth there are three areas to consider: intensity, duration and quality. In order to maximize a plant’s productivity, it helps to understand the light conditions under which it will experience vegetative growth (i.e. Sign up to get all the latest gardening tips!
