I woke up earlier than my brother as every other day of the week. I took a fifteen minute warm shower. It left me with twenty five more minutes to get dressed‚ have breakfast‚ brush my teeth‚ say good bye to my mother and get in the car no later than 7:05. I got to school on time‚ even though my brother came out of the house late as he used to. It was a Thursday. Those first two forty five minute math periods made the morning go by too slow for me. I took the math test and did pretty well at it.

Student Work Portfolio Senior Reflection I’ve been in AITE since my freshman year‚ I walked into the school not knowing anyone and now I’m walking out knowing everyone. I have built so many different relationships throughout my four years being here. I’ve experienced my good and bad days here. I’ve had accomplishments and failures. I feel like I matured a lot‚ not from the school itself but the road and path I took in this school which is something I hope no other student ever experience. I honestly

molecules spread faster and faster. The opposite would be true of colder temperatures. 3. Considering the osmosis lab‚ explain the relationship between fluid volume and osmotic pressure. Answer: Osmotic pressure is the measure of the tendency for osmotic flow to occur. Osmotic flow is from a solvent to a solution. This is the amount of pressure that needs to be applied from the outside to prevent osmosis. Fluid volume might be connected to osmotic pressure as the amount of pressure required to contain

Alfred Wegener was born in Berlin in 1880. His father was a minister who ran an orphanage‚ Alfred was even brilliant as a young child he took interest in the land textures and topography. He took special interest in Greenland‚ and always walked‚ skated‚ and hiked. This prepared him of what was to come in his future. He studied in Germany and Austria‚ receiving his PhD in astronomy. But no sooner than he got his PhD he dropped astronomy (in desire for a more interesting department) to study meteorology

different concentrations of glucose affect osmosis in potato cells. Osmosis is the passive process of diffusing water which means within this experiment particles of water will move from a lower concentrated area to an area of higher concentration ; in this case it will be a concentration of glucose. Diffusion is when particles move from an area of high concentration to low concentration ; for example when a smell of cooking spreads through the house. Osmosis is a vital mechanism in the transport of

retains the solids and contaminants in the water. The membrane is the most important part of the system. It very hard to located problems in the membrane. In addition‚ if the membrane is not in perfect condition‚ the system is not working. Reverse osmosis is a kind of filtration. Filtration is an oldest process that consists in the water passing through sand‚ gravel or membrane. Thus prevent the solids and contaminates passing for the other side. The pores of the filters need to be small. The smaller

Exploration How do increasing sucrose concentrations of 0.0 mol dm3‚ 0.2 mol dm3‚ 0.4 mol dm3‚ 0.6 mol dm3 and 0.8 mol dm3 affect the osmolarity point of potato cells‚ where it is investigated how osmosis changes the weight of the potato cells‚ measured by the percentage change between the initial and final mass of the potato? Independent Variable: Increasing sucrose concentrations Dependant Variable: Mean percentage change in mass of potato cells All cells have a protective barrier‚ one which

The oxygen-hydrogen bonds in water are very polar. Because of the arrangement of the two bonds and two lone pairs of electrons on the oxygen‚ the molecule is bent. (The four sets of electrons are arranged in a tetrahedral arrangement. The angles between these sets of electrons are about 108 degrees) This bent shape makes water polar. Since it is polar (actually very polar) there are considerable intermolecular forces attracting the molecules of water together. The result of these forces is that

What is life you may ask. To me‚ life is the most vulnerable thing on earth for you may lose it anytime. Life is fragile and thus precious. Today you might be happily enjoying it and then for all you know‚ tomorrow‚ you may not live up to it. Life‚ is given to us so we will learn to cherish it be it the good times or bad times. Its funny how some people in some parts of the world choose to give up their life so easily‚ like example suicide but then on the other hand‚ there are people who wants to

People have had someone to influence them in their lifetime at some time or another‚ but my biggest influence in my life is my mom. I can’t but admire my mom’s strength and her wisdom. I am a strong believer in the saying “like father"‚ “like son" goes with both genders‚ however‚ I do think that this is more a result of following example rather than a result genetics. It is common knowledge that not everyone is perfect‚ even heroes‚ and in realizing this I know. Although I wish to be like my mom
