Effects of Cold Weather on Incandescent Light Bulbs Abstract Cold weather hasn’t previously been known to have much of an effect on incandescent light bulbs. But colder temperatures do make electricity flow more smoothly and easily. In this experiment‚ it was concluded that cold weather‚ does in fact‚ affect an incandescent light bulb in a circuit. The tests in this experiment showed that when a light bulb circuit is placed in cold temperatures‚ the incandescent light bulb seems to glow brighter

rate of photosynthesis increased from a cold temperature to room temperature; however‚ the rate of photosynthesis decreased in the body temperature. This means that the hypothesis was rejected. The rate of photosynthesis did increase‚ but only to a certain point. Based on these results‚ it can be concluded that photosynthesis performs better at room temperature that at cold temperature because thee low temperature slows down the reactions taking place in the chloroplasts. Photosynthesis performs

respiration and photosynthesis. Photosynthesis is performed by plant organisms and some bacteria‚ and cellular respiration is performed by all living organisms. These two processes are reliant on each other. Photosynthesis creates oxygen‚ which is used in cellular respiration. Cellular respiration in turn creates carbon dioxide‚ which is an important “ingredient” in the process of photosynthesis. Let’s take a closer look at what makes these processes so important to all living things. Photosynthesis is the

the objects picture a description of what happens when light ray is shone on it. The source of light is a light bulb from a ray box. If a beam of light of one colour is shone through a prism‚ the direction of the beam is changed by the prism. This is because the two faces of the prism through which the light passes are not parallel. If white light is used the prism splits up the light into a series of colours. This shows that white light is actually made up of many other colours - a fact first

to investigate the effects of light and gravity on the growth of sunflower seeds. Background Info: Tropism is directional movement in response to a directional stimulus eg light or gravity. Plants are not able to relocate if they happen to start growing where conditions are nor perfect but they can alter their growth towards more favorable conditions. Plants respond to light (phototropism) where the stems grow towards the light and the roots grow away from the light. They also respond to
