Electromagnetic Radiation Infrared Radiation
1,377 wordsYou might remember the heroic role that newly-invented radar played in the Second World War. People hailed it then as "Our Miracle Ally." But even in its earliest years, as it was helping win the war, radar proved to be more than an expert enemy locator. Radar technicians, doodling away in their idle moments, found that they could focus a radar beam on a marshmallow and toast it. They also popped popcorn with it. Such was the beginning of microwave cooking. The very same energy that warned the B...

The Effect Of Temperature On Air Pressure
1,303 wordsDESCRIPTION: My project consists of a series experiments to determine the effect of air pressure in a given environment at various temperatures. The experiments I chose to conduct are: 1) Heat an ordinary pop can on a hot plate and then putting the can upside down in cold water to see the effect of a fast change in temperature. 2) Partially full milk jug with hot water, put the cap on tightly, and let it sit for one hour to see the effect of a slow change in temperature. 3) Setting a small piece...

Miles Per Hour Warm Air
1,621 wordsWeather is the condition of the air that surrounds the earth. Weather affects our lives in many ways; for example, the type of clothing that we wear any given day depends largely on the weather. If it is cold we put on slacks, if it is hot we slip on shorts.

Life On Earth H 2 O
726 wordsThe first thing water reminds us of is the clear liquid in our water bottles. However, water is more than a normal substance. Water is the beginning and the continual of life on earth. Because of its many unique properties, water was able to start life on our planet. The simple structure of H 2 O is the source of all water's properties. With two hydrogen atoms sticking to an oxygen atom in a tetrahedron shape, water is considered as a polar molecule. Because oxygen is very electronegative, it pu...

Atomic Absorption Spectrophotometry Parts Per Million Water
1,290 wordsThe purpose of this experiment is to explore the hardness of the water on campus. Hard water has been a problem for hundreds of years. One of the earliest references to the hardness or softness of water is in Hippocrates discourse on water quality in Fifth century B. C. Hard water causes many problems in both in the household and in the industrial world. One of the largest problems with hard water is that it tends to leave a residue when it evaporates. Aside from being aesthetically unpleasing t...

Rate Of Reaction Bunsen Burner
2,301 wordsFor this investigation I am going to investigate the effect of the concentration of an enzyme, in this case Amylase, on the time taken for the enzyme to fully breakdown the substrate, which in this case is starch. The reason why these two enzymes have to be used is because each enzyme is designed specifically to break down only one substrate as each enzyme is made of a protein that causes it to be a specific shape, in this case the enzyme Amylase can only break down starch to dextrin. I am going...

Cold Blooded Oxygenated Blood
1,437 wordsMammals have existed for the past 200 million years. According to fossil evidence, they evolved from a mammal like reptile group. These reptile ancestors were small, active carnivores. They were equipped with several specialized types of teeth. Their limbs were positioned more directly under the trunk as opposed to spreading out to the sides. Both of these characteristics are prominent features of mammals. For the past 70 million years mammals have been the dominant animals in terrestrial ecosys...

Source Of Energy Earths Surface
683 wordsAll life on Earth depends on energy from the sun. Solar energy is the source of energy for photosynthesis. It provides the warmth necessary for plants and animals to survive. The heat from the sun causes water on the Earths surface to evaporate and form clouds that eventually provide fresh rainwater. Solar energy is the result of thermonuclear fusion reactions deep within the sun. These reactions produce so much energy that they keep the surface temperature of the sun at about 10, 300 B 0 F. Eve...
