Water molecules move from where there’s a lot to where there’s a little water concentration which is called osmosis. This makes vinegar a hypotonic solution. After being left in syrup, the eggs calcium shell hardened. The egg became smaller in size. The raw egg, before being dropped in syrup it was put in vinegar and it measured 150mm in width and 200mm in length.

Purpose/ objectives: 1. To learn if food concentrations affect yeast activity 2. To improve skills in writing a lab report better 3. To practice measuring skills 4. To understand how yeast works Materials: * * 6 identical large test tubes (18 X 150mm) * 1 graduated cylinder (24ml) * Molasses stock solution ( 1:4- molasses: water) Dropper * Yeast suspension (1 gram of dry yeast in 100 mls water) * Aluminum foil * 1 test tube rack * 1 graduated cylinder (small) * 1 beaker * 6 small test tube (10 X 75mm) * Rule marked in millimeters Hypothesis: If you add more molasses to the yeast then the gas would became greater because the yeast cells reproduce so the waste became greater and
