How does light intensity affect the rate of photosynthesis? Poorly Pondweed Questions 1) How does light intensity affect the rate of photosynthesis? 2) How does temperature affect the rate of photosynthesis? sunlight carbon dioxide + water glucose + oxygen chlorophyll sunlight 6CO2 + 6H2O àààààà C6H12O6 + 602 chlorophyll Prediction I predict that the more intense the light‚ the higher the rate of photosynthesis. To photosynthesise‚ plants need light. It provides the energy for the process

Armadillidium vulgare‚ naturally prefers: wet or dry environments along with a light or dark environment. It was hypothesized that a Pill bug would prefer and wet and dark environment based on its natural habitat of soil. For the wet and dry experiment‚ a coffee filter and soil were placed in each chamber of a double petri dish with one being dampened before being placed in. For the light and dry experiment a light was hung above one chamber of another double-chambered petri dish while the other

electric light bulb‚ using a carbon filament. (Collier 66) An incandescent bulb consists of a filament‚ which today is made of a wire of tungsten‚ and Anchor wires‚ which hold the filament in place. Also a flare‚ Which has two red wires that run through the to the base of the bulb to the filament‚ and an exhaust tube as well‚ which is a space where air is sucked out of the bulb to create a vacuum. It would also include a glass bulb‚ which is a base to help screw light bulbs into lamps and light fixtures

Fluorescents or Long Fluorescents using plasma discharges use only 1/4 of the energy and heat of incandescent lights‚ which derive their light from heating filaments hot enough to emit visible light. If every home changed their five most used lights‚ they would save $60 per year in costs. This would also be equal to 21 power plants. The fluorescents also last up to 10 times as long. Replacing one bulb means 1‚000 pounds less CO2 emitted over the compact fluorescent’s lifetime. Traffic signal

Lighting – LED Technology 1. What is it LED light bulb refers a solid-state lamp that uses light-emitting diodes as the sources of light. LED light bulb produces light when electrons move around within its semiconductor structure. It has a longer service life and high higher energy efficiency than other source of lighting such as fluorescent and incandescent light bulb though its initial cost is much higher. LED light bulb has wide range of applications including both general and specific.

environmentally friendly‚ but after conducting research‚ I believe that one small additional change will cut our company’s utilities greatly. Background and Purpose Starbucks Corporation can become more energy efficient by using LED light bulbs instead of standard incandescent lights. About 80 percent of our company’s total carbon emission solely comes from the energy use in our stores. This means that energy use is our single biggest impact on the environment‚ but it is also our biggest opportunity to make
