DEFINITION ANAEROBIC POND Anaerobic ponds are deep treatment ponds that exclude oxygen and encourage the growth of bacteria‚ which break down the effluent. It is in the anaerobic pond that the effluent begins breaking down in the absence of oxygen "anaerobically". The anaerobic pond acts like an uncovered septic tank. Anaerobic bacteria break down the organic matter in the effluent‚ releasing methane and carbon dioxide. Sludge is deposited on the bottom and a crust forms on the surface as show in

Egg Drop (lab writes) In our science class we did an egg drop experiment. We used the scientific method to answer the question and solve the problem. Our question for this particular lab was “will an egg break or be secured‚ if covered with thick sponges and drop from ten feet above the ground?” our idea was to secure the egg from breaking and we wanted to design something that would provide a lot of cushioning directly on the egg. We came up with many different ideas until we choose

The Egg Drop Analysis 1. As far as researching goes I did not do many research besides videos I mainly saw a lot of sponges or big sponges use for people experiment and I in fact went with it and prototypes I used were mainly the same thing with some added cushion to it. 2. I forgot to take a picture but a good description would definitely be a can and thats wrap in cushion on the inside and the outside but the error I made was not covering the metal shock that will it takes impact it release

Save water‚ save life Water is necessary for life. Water is needed for domestic‚ agricultural and industrial purposes. Three-fourth of Earth ’s surface is covered by water bodies. 97 per cent of this water is present in oceans as salt water and is unfit for human consumption. Fresh water accounts for only about 2.7 per cent. Nearly 70 per cent of this occurs as ice sheets and glaciers n Antarctica and other inaccessible places.

“Water is essential to the sustenance of life” Give three examples: 1. Water’s polarity 2. Water’s H Bonds 3. Cohesive property of water The polarity of water makes water essential to the sustenance of life. It allows water to be a good solvent and form many different solutions.

The polarity of water also causes different
