effect of concentration of acid on the rate of diffusion in agar blocks? Aim: To investigate how the concentration affects the rate of diffusion of hydrochloric acid through agar blocks Research Question: To determine how will different concentrations (0.1M‚ 0.2M‚ 0.3M‚ 0.4M‚ 0.5M) of hydrochloric acid affect the rate of diffusion of sodium chloride through agar blocks? Introduction-include prediction; information you have researched before Diffusion refers to the passive movement of molecules along

How feedbacks help a team As a member in the group‚ it is important to give feedbacks to others which will increase the effectiveness within the teamwork. What the article tells me is that how to improve the word choice for feedbacks in order to avoid the negative consequences. By using the descriptive words instead of evaluative ones‚ useless anger toward others can be avoided. For instance‚ by point out the problems one have in doing certain task is much better than categorize the person. Furthermore

Peaceful resistance to laws positively affects society. By following a law one agrees with it. For the most part laws are just and by following them one can contribute positively to society‚ but there are unjust laws. By following an unjust law simply to prevent personal harm one is agreeing to the terms of the law. In agreeing to the law it is strengthened and others are more likely to follow. It is in this way that “injustice anywhere is a threat to justice everywhere” (Luther) due to the

he policies and procedures put in place at school help children to feel safe. For example‚ a behaviour policy that highlights the code of conduct expected from all children reassures the child that the school have consequences in place if a child is being unsafe. This may include if a child is being unsafe with equipment in class that child will get a negative consequence. Similarly‚ if a child gets bullied theyâ€TMll know something will be done about it as the school bullying policy highlights the

Cell Size: Is Bigger Better? Problem: Why are cells small? Objective: To see the relationship between cell size and diffusion of materials. Hypothesis: If we cut three different sizes of cells‚ then the smallest one will survive the longest due to its sufficient permeable membrane.

Summary: Paul Krugman‚ Nobel Prize in Economics in 2008‚ made a remix of a previous book on the Asian crisis to explain the crisis of 2008. Examines with an entertaining crises that followed the Great Depression of 1929 and focuses on Asian and Latin American 90s and 2000‚ he drew attention for its stagnation. He says that when all augured an era of unlimited growth after learning the lessons of the Great Depression and the elimination of the cyclical crises in Asia happened just the opposite. For

Process of Diffusion and its importance in living organisms Diffusion is the movement of molecules or ions down a concentration gradient i.e. from an area of high concentration to an area of low concentration. For a diffusion system to be efficient‚ it should have a large surface area so that high amount of substances can be exchanged at a time. It should also have a thin membrane and a continuous supply of substances‚ as a thin membrane means that the diffusion pathway would be short‚ and the continuous

Lab Report on Osmosis and Diffusion Biology 1‚ Period 3 March 15‚ 2010 Lab Team: Jason Perez‚ Kicia Long‚ Chris McLemore Purpose: The purpose of this lab is to observe the acts of passive transport: diffusion and osmosis in a model membrane system. The experiment will show how molecules in solution move from areas of higher concentration to areas of lower concentration. The model membrane is dialysis tubing. Materials Used 2.5 cm dialysis tubing 15% glucose
