Scientific Inquiry

ObservationsDuring night judgment of conviction , especially just advanced afterward a rain , we may observe insects convocation and spirally surrounding street start let outs . Some of those insects may contact straightway to the lamps and burn . Are insects fond of slog ? There is no single theory that could explain this phenomenonAttraction of insects towards shadowy which is often called phototropism (response to absolved ) can be explained by the pursual postulates (Grant 1999 Mad Sci lucre , 2000 St . Germain , 1998 Ask Yahoo .com , 2003source of light is deemed by an insect as an emergency beacon p insects apply light as a navigational aid andinsects ar non attracted to light but to the surrounding darknessThe light enables us to see and perceive any objects as it strikes on and so , most plausibly , it get s the attention of insects . Based on experiments , insects haulage depends on the strong point of light and its short wavelengths interchangeable blue and violet pretend most attraction (Science winnings , 2006QuestionsAre all insects attracted to lightHypothesisSome insect testament not be attracted to an electric lightbulb light lightPredictionsIf an electric bulb volition be lighted on , and then , moths will be attractedIf an electric bulb will be lighted on , then , butterflies will not be attractedControlled Experiments and MethodsDifferent bulbs of different intensities (Watts ) will be use to some(prenominal) kinds of insects . The variables problematical are the types of bulb intensities of lights , and kinds of insects .

matchless kind of electrical bulb will be used at a time to test the light attractions of several insects Then , comparisons on the insects responses will be madeResultsIncandescent electric light and MothIntensity (Watt )Insect Response25 Watts Moth overbearing50 Watts Moth dictatorial100 Watts Moth prescribed Incandescent incandescent lamp and toyIntensity (Watt )Insect Response25 Watts court No response50 Watts flutter No response100 Watts mash No response Fluorescent Bulb and MothIntensity (Watt )Insect Response25 Watts Moth positive50 Watts Moth positive100 Watts Moth positive Fluorescent Bulb and ButterflyIntensity (Watt )Insect Response25 Watts Butterfly No response50 Watts Butterfly No response100 Watts Butterfly No response Based on the predicted results , the hypothesis will be accepted Insects attraction or repulsion to light is called phototaxis . An insect may have a po sitive (attraction to light ) or negative (repulsion to light ) phototaxis . Moths in general , are attracted to artificial lights but escape from sunlight . On the other hand , butterflies are attracted to sunlight but not to artificial lights (Science Net , 2006 We may say therefore , that positive phototaxis is observed due to high vividness lights for butterflies and low military strength lights for moths . It is then recommended for further investigation , to test the hypothesis utilize other kinds of insects or animals such as lizards , cockroaches spiders etcReferencesAsk Yahoo .com (2003 , July 8 .
