Hi there,
The easiest thing to do would be the potato test. you need to cut out say 5 pieces of potato making sure they mesure and weigh exactly the same. Place them in sseparateglasses with the same amount of water in each. However the only ddifferencein the water is the cconsent rationof sugar in it. aalways do one lot of water with no sugar in it!

have two glasses of water, add salt to one of them,put lettuce in each, observe changes in the lettuce. one will be turgid while the one with salt would be flacid.

strawberry in water. take a beaker and put water in it. put 4 toothpicks in a strawberry. angle them down so the strawberry sits in the water. leave it for a time and the strawberry will grow. this is because there is more water outside the strawberry so it equals out by letting more in. if you want the opposite, mix sugar into the water and it should shrivel a bit.

Use cellophane paper as a semi-permeable membrane.

Make it into a sort of a bag after adding a salt water solution.
Immerse it in a beaker of pure water and after a few hours check on it

It would have become turgid due to osmosis

Or alternatively you can attach a thin glass tube to the cellophane paper, tie the paper around the tube and check after a few hours to see that the level of water in the tube has risen.
