Requirements in Science IV Submitted By: (name) February 16‚ 2011 ABSTRACT Black Light is also referred to as a UV light. A lamp that emits electromagnetic radiation almost exclusively in the soft near ultraviolet range that is only partially visible. Black Light as used to detect money helps us protect from fraud and for our security and theft prevention. This thesis contains

Science Investigatory Project LAVA LAMP [pic] Background of The Study A lava lamp is a decorative tube-shaped light fixture containing a colored‚ oily fluid that flows up and down throughout the lamp chamber in a manner reminiscent of molten lava. As the fluid rises and sinks in the lamp chamber it changes shape and breaks into globules of various sizes‚ giving a psychedelic effect of constantly shifting patterns. Credit for the creation of the lava lamp is given to English engineer Craven

Energy Saving Tips to Use Throughout the Year * Be sure to turn off lights when you leave a room. * Turn off machines when you leave a room (examples include TV’s‚ computers‚ radios‚ stereos‚ video games‚ VCR’s‚ and DVD players). * When you go away on a trip‚ be sure to unplug these same machines because they have stand-by functions that consume electricity even when they are turned off. * Fill your dishwasher efficiently and limit the number of times you run it. * Don’t put furniture

demonstrated that red and blue rays maximize this process (Rothenburger‚ 1993). The purpose of this experiment was to examine the effect of several different light sources on plant growth. The Five lights sources studied were incandescent‚ black‚ fluorescent‚ colored‚ and natural light. Past research in this area has shown that natural light produces the healthiest plants‚ because it contains an even amount of red and blue light waves. Humans cannot see light waves. Though we cannot see the distribution

are affected by devices oscillating in the same frequency band. Aim To test if - a TV; a microwave oven in use; a mobile phone making a phone call; a TV remote control; water surrounding the aerial; a thin-metal box; an incandescent light bulb; a fluorescent light bulb – causes interference with AM and FM radio reception. Hypothesis I think that a TV will affect AM reception‚ but not FM reception‚ because TV’s will give off electrical pulses which will interfere with AM radio‚ but not FM. I think that

Benito REACTION PLAN Ways to Slow Down Ozone Depletion Global warming refers to an increase in the average temperature of the Earth as a result of the greenhouse effect‚ in which gases in the upper atmosphere trap solar radiation close to the planet’s surface instead of allowing it to dissipate into space. Both natural and human-made

A light-emitting diode (LED) is a semiconductor light source.[6] LEDs are used as indicator lamps in many devices and are increasingly used for other lighting. Appearing as practical electronic components in 1962‚[7] early LEDs emitted low-intensity red light‚ but modern versions are available across the visible‚ ultraviolet‚ and infrared wavelengths‚ with very high brightness. When a light-emitting diode is switched on‚ electrons are able to recombine with holes within the device‚ releasing energy

first preparing our fast plants we had to set up four different systems that would dictate our variable of fluorescent light. Each system would provide light to our fast plants for different amounts of time per day. Our systems were set up for 0 hours of light‚ 6 hours of light‚ 12 hours of light‚ and 24 hours of light. To setup the lab we began to setup our lighting system with fluorescent a timer for each set of fast plants. Our 24 hours was set up in the classroom with a lighting system directly
