    out if the color of light a plant receives‚ affects the plant growth. Light is electromagnetic radiation that comes in waves‚ the basic units of which are called photons. Plants use light to turn carbon dioxide into sugars necessary for growth‚ a process called photosynthesis. Sunlight is a full spectrum of different wave lengths of light. Seen through a prism‚ this spectrum turns into bands of color: red‚ orange‚ yellow‚ green‚ blue‚ indigo and violet. (Stern‚ 2004). The light of the sun is white

    Light Intensity Characteristics of Photocells The photoelectric effect is defined as the emission of electrons from a material by visible light. The cadmium sulfide photocell is used to act as a conductor once exposed to light‚ allowing light to travel through. However it also acts as an electric resister (an opposition to a current flowing in a circuit) once not exposed to light. The photocell serves today ’s cause in a sufficient manner. It is used for a variety of reasons but it is mainly

    Properties of Light Purpose: The ideal purpose of this lab activity is to investigate the relationship between the frequency of the light (color) and the energy produced by different colors of light. Other purposes of this experiment include calculating the proper current for each LED‚ measuring the evaporation rate of rubbing alcohol‚ and being able to discuss the outcome of the relationship in light energy and the color of the light producing the energy. Materials: Light Emitting Diodes

    Light Lab Introduction: The purpose of this lab is to observe how influential light is to the construction and/or use of CO2 and O2 amongst plants. This can be examined by experimenting the effects of plants under both light and no light. In order to begin this experiment you must begin by wrapping the “BioChamber” with aluminum foil to prevent light from coming through to the leaves‚ however‚ once the lid has been covered you are to poke holes so you can insert the sensors. Next‚ you will

    Each element emits a unique color light. The purpose of this experiment was to observe these unique colors and calculate their energy. In order to observe this‚ we placed the physical elements in a 24 well plate‚ dipped wet q-tips into the wells to gather the element‚ and put it over the bunsen burner to observe the flame emitted. While observing the different flames‚ we saw that different elements did indeed emit unique flame colors. Colors such as red‚ violet‚ and turquoise were emitted. All of

    The Effects of Light Intensity on the Rate of Photosynthesis Aim: To investigate the effects of light intensity on photosynthesis. Background: Photosynthesis is a process that plants undergo to produce glucose. The plant then uses the glucose to produce energy which the plant needs to sustain life. The chemical formula for photosynthesis is: Sunlight 6CO2 +6H2O → C6H12O6 + 6O2 Chlorophyll The plant requires light‚ carbon dioxide and
