reaction will occur more slowly. I think that as we move the lamp away (and therefore reduce the light intensity) from the elodea pondweed the number of bubbles produced will decrease steadily. For instance‚ say at 10cm distance 50 bubbles are counted‚ it is likely that at 20cm distance 25 bubbles will be counted‚ as the lamp is twice the distance away. This means the rate of photosynthesis is halved. I think that if we move the lamp any further away than 50cm no bubbles at all will be produced

is placed against the wall from one end of the room to the other‚ which has a dresser on one side where as the other side has a place to put books‚ novels and so on. Usually people prefer side tables on either side of their bed for a lamp‚ but I would like lava lamps that light up as the lights are switched off during the night‚ hanging off the ceiling‚ low enough to be able to touch it‚ on either side of the bed. The colours would be one that matches the one of the room. For the colour of the room

Pompeii was a great city in ancient Rome that was abruptly destroyed when the seemingly harmless and docile Mt. Vesuvius unexpectedly erupted destroying the city of Pompeii and the bordering city of Herculaneum. Before this tragedy struck Pompeii was a very wealthy city and a staple of Roman culture. Located just 10 Kilometers from Mount Vesuvius‚ Pompeii appeared to be nothing more than a wealthy city with a view of great mountain until its one defining moment in history changed everything.

(AA/AAA battery). However‚ producing 1.5 volts does not necessarily produce enough current to make the lamp actually power up to full use. Voltage is only the POTENTIAL to do work. (See Ohm’s law: V = I x R) This kind of battery generally produces only a few milliamps. Even multiple potatoes may not generate enough amperage. Most assuredly‚ it will NOT power a household light‚ but a small flashlight lamp will GLOW. Cut the potato in

Also‚ with the surface as liquid-like as it is‚ its surface is constantly refilling all impact craters with molten lava. This lava ’s contents are not exactly discovered yet‚ but scientists are led to the belief that it contains sulfur

And then‚ tired of reading‚ one might rise and see for oneself‚ the house all empty‚ the doors standing open‚ only the wood pigeons bubbling with content and the hum of the threshing machine sounding from the farm. "What did I come in here for? What did I want to find?" My hands were empty. "Perhaps its upstairs then?" The apples were in the loft. And so down again‚ the garden still as

Some people identify Texas with cowboys‚ horses‚ oil‚ or even J.R. Ewing – but not me. I think of the great food of Texas‚ and that food is chili. A staple dish in my household‚ chili is a dish with a long history. From the “pioneer” days of the early West to today‚ chili remains a favorite among many in the West‚ but particularly in Texas. My chili recipe is based on the contributions of friends‚ relatives‚ and hometown chili parlor. Prepared with its own special ingredients‚ my Texas Chili

When the flowing frozen nitrogen slowly warms up‚ parts of it rise up to the surface like splotches in a lava lamp. These bubbles cool down and sink to the bottom again. This leaves room for new bubbles to raise and take their place. They believe that these cells sometimes merge together in sets before they sink down‚ which could help make some of the more complex

This is a lawful crime in the United States and is taken very seriously when a human’s life is in danger.
