of photosynthesis has a direct reflection on the amount of oxygen that is produced Complete a lab report using the scientific method. What effect does the intensity of light have on the rate of photosynthesis (measured as the number of oxygen bubbles)? The higher intensity of light creates more oxygen‚ while the least amount of light produces a lesser amount of oxygen. Is it possible to examine the relationship between photosynthesis and cellular respiration under controlled experimental conditions

many inventions‚ including the telegraph and the light bulb and when he failed‚ he didn’t give up‚ he kept on working on it until he got it right(Thomas Alva Edison).” Thomas Edison was one of the greatest minds of the 1900s he helped the people leave the dark age and to the light age by making the light bulb. It took Thomas Edison 1000 unsuccessful attempts to invent the light bulb and he never gave up that is how determined he was to make the light bulb. Thomas Edison not only invented many things

CONCEPT OF WIRELESS ELECTRICITY (Wi-Tricity) Our forefathers marveled at the invention of glowing light bulbs by Thomas Edison in 1879. However‚ to us 21st centurions‚ the light bulb is nothing out of the ordinary. When computers‚ cell phones‚ laptops‚ iPods‚ etc. were invented our antennas tweaked. Now this is what you call invention! However‚ as time’s progressing we are getting used to these devices. In fact‚ charging all these appliances has become so very cumbersome. Each appliance has its

Electricity Saving At Home Replace old light bulbs with new florescent bulbs. Turn off the lights when not in use. Never leave electrical appliances on a standby. Keep doors and windows closed when heat or air conditioning is on. Check heat setting on the water heater. By lowering down the temperature you can reduce electricity

Converting Saltwater into Electricity I. Introduction The world we live in is abundant with food‚ life and resources‚ but we continue to use up non-renewable resources in massive amounts. As a result‚ the many nations and countries of the world will have to deal with water‚ food‚ and energy shortages‚ as an effect of overpopulation. This Project presents a new‚ derived energy source. It will also discuss the methods and ways we can utilize this environmentally-friendly resource to produce an efficient

Anthem displays Equality as becoming an individual‚ but that is not the only reason he breaks away from his civilization. Equality defies the teachings and stands up for what he believes in even if he is killed. Equality’s motivation for creating the light bulb makes him a sacrifice for the advancement of mankind.
