Osmosis Experiment

Osmosis Experiment

Aim:

The aim of this experiment is to show how osmosis works in a plant

cell.

Plan: Method

The ways we will do this experiment is firstly by getting a beaker and

put a 100ml of water in it, then get a visking tube and put it in the

beaker, so we don't block the holes with natural grease on our hands.

After, we will get another beaker and pour some 1% sugar solution in

it. When we have done this, we get one end of the visking tube and

'ruffle' it, then we get some string and one person will tie the end

of the tube, while the other person hold it. The visking tube then

will go back in the water, while we get a dropper and the beaker of

sugar solution. After we will use the dropper to slowly and neatly

pour the 1% sugar solution in the visking tube; we will fill it up ¾

of the way. Then again one person will tie the other end; while the

other person holds the tube, so now we have both end tied- we will

make sure they are no leaks. When we have done this, we will take the

beaker with water and visking tube to a weighing machine; we will then

take the visking tube out and measure the mass of it (in grams).

After, we will put the visking tube back in the beaker and leave it

there for about 20 minutes. When the time is up, we will measure the

mass of the visking tube again (in grams). During the experiment, we

will observe the visking tube during the 20 minutes and see if the

mass has increased or decreased at the end of the experiment.

This experiment could be repeated, but using a 10% sugar solution,

which would have helped us differ the different mass increase or

decrease in both of them. We were planning to do this one to, but

unfortunately-due to fewer supplies of visking tubes we could only
