Investigating the Osmosis Effect in Potato Cores Aim The aim of this experiment is to investigate the osmosis effect in potato cores while they are submerged in different concentrations of sucrose solution. Osmosis will take place while the potatoes are fully submerged in the sucrose solution. Apparatus æ Scalpel (1) æ Tile (1) æ Pr.

Investigating the Water Potential Of Potato Cells Aims 1. To test how water potential‚ in a solution‚ affects the movement of water in and out of a cell by osmosis Prediction I predict that by increasing the water potential around the outside of the potato cell‚ (i.e. so that the water potential is greater outside the cell compared to the inside of the cell e.g. 0m sucrose) that the net movement of water into the cell will increase. This is due to the water potential being greater outside the cell

Investigating Factors that Affect the Strength of an Electromagnet Aim: To investigate the factors‚ which affect the strength of an electromagnet‚ also known as it’s‚ pick up power. Predictions: The more coils of wire used on the electromagnet then the greater number of paper clips picked up. Also The greater the current the greater the number of paper clips picked up. There will also be a limit to the amount of magnetism created and how many paper clips can be picked up

Investigating arteries and veins Methodology 1. Suspend a ring of artery from a hook on a clamp stand. 2. Use a metre rule to record the length of the ring once the mass carrier has been attached to the free end of the ring. 3. Attach a 10 g mass and record the length of the ring after the mass is added. 4. Remove the mass and record the length of the ring. 5. Repeat steps 2 and 3 using 20‚ 30‚ 40 and 50 g masses. Record the length with and without the masses each time. When comparing

Investigating Factors That Affect Rates Of Reaction Aim: How does the mass of calcium carbonate affect its rate of reaction with hydrochloric acid? Hypothesis: I hypothesize that when the mass of the calcium carbonate increases‚ the rate of reaction of the calcium carbonate and hydrochloric will also increase. The collision theory states that the more successful collisions there are within the reaction‚ the faster the rate of reaction. When the mass increases‚ so does the number of particles

Investigating the effect of discomfort on reaction time Purpose and method The purpose of this investigation was to investigate the effect of discomfort on reaction time in humans‚ measured by dropping a ruler into a subject’s hand. Discomfort was caused by a bowl of ice. Background information Information is carried from the sensory receptors to the central nervous system and back the to effectors by means of nerves. When a number of different processes are involved (a situation informally

Investigating the Effect of Temperature on the Permeability of Membranes The permeability of membranes can be altered in several ways. From previous preliminary work I know that reagents‚ for example detergents and alcohol alter the arrangement of the phospholipids in the membrane allowing substances to leak out of the cell. Temperature also affects the membrane. As membranes relay on protein molecules to allow molecules to enter and leave the cell through facilitated diffusion the temperature must
