Module 6 Weather And Climate Changes - 1179 Words

Module 6: Weather and Climate Changes Students are to understand the four major greenhouse gasses in the atmosphere and perform two experiments to address the hydrologic, or water, cycle. One experiment requires 20 ml of 60  °C put into a sealed canning jar with a petri dish filled with ice on top; this experiment is used to visualize the water cycle. Then, for the second experiment, students are to construct two identical plastic bags, each filled with 200 ml of room temperature sand and 200 ml of room temperature water. One of these bags is to be exposed to sunlight for 12 hr and the other to the shade for the same amount of time; this experiment is used to visualize water infiltration and the hydrologic cycle. Greenhouse Gases There†¦show more content†¦When the water condenses enough to form larger droplets, these droplets overcame the water’s surface tension and dropped from the canning lid or flowed down the side of the jar in the form of precipitation and runoff. This portion of the cycle continued until the experiment was concluded at the 30-minute mark. The heating of the water definitely expedited the evaporation process of the water though; this was witnessed early in the experiment. Water droplets formed quickly when the water was hot, and near the end of the experiment, when the water was cooler, there was not a noticeable change in condensation. While witnessing this, it can be concluded that the cooler water will evaporate slower and hotter water will evaporate quicker. This can easily be tested by using cold water instead of the hot water that was required by the lab. Without a soil base, plant fauna, and a large enough area infiltration, groundwater flow, transpiration, and transportation were not witnessed in this experiment. To get a full spectrum of the water cycle, a large enclosed environment filled with a portion of soil would be needed. On one side of this container would have the soil and plants with a heat source above it. While on the other side, a large pool of water is placed with a large rock in the center. Above this side is a large cooling source. The water from the pool would infiltrateShow MoreRelatedThe Science Of The Module ( Climate Change ) Essay1248 Words   |  5 PagesWith regard to the topic of the module (climate change): 1.

The research process has not only given me time to learn more about a subject I find so important, but I have gained much more knowledge about climate change in general, and the experience has taught me how to critically look at opposing sides to a topic just as intently as I would my own view. In module 1, I learned ways that helped me come up with ideas to develop theRead MoreLayers Of The Atmosphere- Bri Caamano1178 Words   |  5 PagesThe Atmosphere- Bri Caamano Our atmosphere on Earth has many different layer which protect us from the harmful elements in space. Our atmosphere is divided into five layers. The troposphere is the first layer closest to earth. In this layer weather occurs, this is also the closest layer to us. The second layer would be the stratosphere. The stratosphere is one of the most stable layers. Due to the stability of this layer jets and aircrafts fly within this area. The Mesosphere is the thirdRead MoreSolar Energy Pros and Cons1990 Words   |  8 Pagesoxide, sulphur dioxide and mercury that come from many traditional forms of fuels have been kept from being released into the atmosphere, also it greatly contributes to the decrease of harmful green house gas emissions that affect our climate. The warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global mean sea level. The Earths average surface temperature hasRead MoreElectricity Via Natural Sources : Solar And Wind Energy1260 Words   |  6 Pagesboards change over the sun s beams into power by energizing electrons in silicon cells utilizing the photons of light from the sun. This power can then be utilized to supply renewable energy to our homes. Solar panels are the devices that convert light to electric energy, which are called solar panels. The powerful source of light is available from the Sunlight, which are called Sol in technical world. Solar electricity is a reusable form of energy. Solar panels are called as modules which containRead MoreEssay on The Global Warming Controversy3199 Words   |  13 PagesThe globe is being rocked by extreme weather and the hottest temperatures on record. As the average global temperature soars, there are floods, droughts, unusually cold winters, forest fires, and huge storms. Are all of these horrors being caused by human-induced global warming? The source of global warming is a very controversial topic. Some scientists think that global warming is a natural part of the Earth’s cycle because the Earth has always had natural heating and cooling cycles. OtherRead MoreSolar Radiation Resource Assessment Stations2320 Words   |  10 Pagesunder an acute power crises, the Government of Tamil Nadu has recently unveiled its new Solar Energy Policy which aims at increasing the installed solar capacity from the current approximate of 20 MW to over 3000 MW by 2015. The policy aims at fixing a 6% solar energy requirement on industries and residential buildings for which incentives in the form of tax rebates and current tariff rebates of up to â‚ ¹1 (1.5 ¢ US)/unit will be applicable to those who comply with the Solar Energy Policy.
