1. Provide aim and background information 1.1 Diffusion is the process which molecules dissipate into a solution evenly over a period of time. An example is putting sugar in your coffee‚ after a while if you don ’t mix the solution‚ the sucrose will over time‚ go through the process of diffusion and be distributed throughout the coffee. Osmosis is movement of H2O molecules passing through a permeable cell membrane to the less concentrated solution‚ eventually to reach an equivalent number of molecules

City-States vs. Empires The first civilizations emerged thousands of years ago in a region in the Middle East called Mesopotamia. Around 4000 B.C.E‚ a group called the Sumerians invaded Mesopotamia and organized their civilization‚ Sumer‚ into many city-states. A city-state is a self-governing state that consists of a city and its surrounding territory. Some Sumerian city-states include Kish‚ Uruk‚ Lagash‚ and Ur. In these city-states‚ the Sumerians would develop a sense of culture and create

Egypt and Mesopotamia were both similar in the way that government controlled the irrigation systems. These early river valley civilizations formed by the fertile lands so that farmers don’t have to live a nomadic life. There religious ideas were both

Early civilizations often had many similarities in their politics‚ economies‚ and social norms. The civilizations of Mesopotamia‚ or the Fertile Crescent (3000 BCE)‚ and the Nile River Valley (3000 BCE) are prime examples of this‚ but with different geography‚ leaders‚ and resources many differences divided the two nations. Both the Nile River Valley and the Fertile Crescent had authoritarian governments and mainly agricultural economies‚ but the Nile River Valley was much more unified‚ while Mesopotamia’s

Mesopotamia and Egypt were two of the most well known civilizations of their eras. Civilizations are defined societies distinguished by their reliance on sedentary agriculture‚ their ability to produce food surpluses‚ and the existence of nonfarming elites‚ as well as merchant and manufacturing groups. Although the political structures and cultural ideas of these civilizations differed‚ some of their social structures were similar. The political and cultural ways of life were completely different

The relationship between shape and diffusion rate Aim- To investigate the relationship between the shape of an object and the time taken for a substance to diffuse to its centre. Hypotheses- Part A) The 5x5x2.5mm block will turn clear first as the Surface area to volume ratio is high and the 10x10x10mm block will take the longest to completely diffuse the Acid to its centre. Part B) The flat‚ rectangular block will be the first to completely turn clear due to its high Surface Area/Volume Ratio

When comparing how Mesopotamia developed into a successful civilization with Egypt during the foundations period there are many similarities and differences. they were similar in that the rivers are what help the civilization prosper. This was because a rivers provided resources for survival. They were different in that the way their rulers maintained order because of different political systems. They were also similar in that they both constructed monumental architecture. This was because it shows

Emily K 20 August 2013 Diffusion Lab Research Question: How does the amount of water in a beaker affect the rate at which food coloring diffuses to the bottom of the beaker? Independent Variable: Height of water in beaker (Inches) Dependent Variable: Rate of diffusion (seconds) Controlled Variables: * Size of beaker * Temperature of water (23°C) * Type/color of food coloring * Person Timing * Environmental conditions Materials: * Beaker(well over 4 in tall) * Food

Aim:To discover what factors affect the rate of diffusion of potassium permanganate crystals in water. Statement:What will happen? How will room temperate solutions or heated solutions increase the rate of diffusion of the potassium crystals?Hypothesis:Heat will speed up the process of diffusion because heat will give out energy that will be able to speed up the process of spreading the potassium molecules.

ancient Egypt and Mesopotamia lived in two different locations and interacted with two different environments. Both places were affected by water in different ways. Euphrates and Tigress rivers shaped the development of Mesopotamia whereas‚ the Nile‚ shaped the development of Egypt. At the end‚ the people of these lands were able to use this water to their benefit. Mesopotamia is the land between the rivers Euphrates and Tigress. In the time when the first people arrived at Mesopotamia‚ it had a very
