back and forth through membranes with little difficulty. This process is known as osmosis. The direction of motion is regulated by the relative concentrations of water and dissolved substances inside and outside the cell. Water will move from an area of high concentration of water molecules (low concentration of dissolved particles) to an area of low concentration of water molecules (high concentration of dissolved particles). It is difficult to observe osmosis at the cellular level since cells are

Osmosis Lab: Potatoes and Elodea Background Information: Cells have a need to regulate their internal environment. They need to be able to this because cells often find themselves in environments where the concentration of dissolved solids outside the cell is different from the number of dissolved solids inside the cell. Since the solids can not move across the membrane‚ the cell responds by moving water either into or out of the cell in an attempt to balance the number dissolved particles.

from 0.93-1.04 grams from the solutions containing AgNO3 (Table 1). Graph one depicts the correlation of percent change in weight for each sucrose concentration with AgNO3 added. The initial length of the potato cylinders were 2cm as depicted in table two. Graph two depicts the correlation of percent change in length in different sucrose concentrations. The initial weights for the solutions lacking AgNO3 ranged from 1.0-1.7grams (Table 3). Graph three displays the correlation for the percent change

Effects of Different Concentration of Catalyse on Hydrogen Peroxide Aim: In this investigation I will try to find how long it takes for the filter paper disc to rise up whilst varying the amounts of concentration of catalyse. Prediction: I predict that the lower the concentration of catalyse the longer it will take for the filter paper disc to rise to the surface of the tube. Equipment: 1. Hydrogen peroxide in a container 2. Flat bottom tube 3. Tweezers 4. Filter paper

Concentration Camps Did you realize that over 1 million people died at the Auschwitz camp!Auschwitz was the biggest concentration camp.It was the only camp left after the end of World War 2. Concentration camps were designed to remove Jews from Europe. They were a strenuous and cruel place to live. The concentration camps were created in 1933-1945 by Hitler and the Nazis. Auschwitz was the largest concentration camp. Hitler and the Nazis made Jews‚ and people they did not like‚ build the camps

A concentration camp is where people got captured and taken to. These people get taken by the Nazis and go to a camp. In these camps some torched‚ beaten‚ some have a disease. This was a place for punishment. Hitler got a group of people called the nazis and rounded up millions of people to tourche in these concentration camps. Concentration camps are a brutal place. Over 40‚000 men‚ women‚ babies‚ kids people of all sorts got taken. Some people tried to hide out but it didn’t really work out for
