Background Research I’m doing my science project on which food wrapping will prevent freezer burn the best aluminum foil‚ plastic bags‚ or freezer paper. This experiment seemed interesting to me because a lot of people get freezer burn on their foods. My mother also gets freezer burn on her foods a lot and she always tries different food wrappings but none of them seem to work. This project will benefit people from getting freezer burn on their food‚ and so they will know which wrapping

Method: 1. Prepare leaves the lesson before. Put a strip of alluminium foil over the middle of completely green leaves. On variegated leaves put the foil in the middle section leaving a border around the edge uncovered. 2. After 24 hours (next lesson)‚ bring the leaves into classroom. 3. Set up Bunsen burner‚ tripod and gauze mat. 4. Bring about 75mL of water in 100mL beaker to the boil. Take foil of leaves and place them in the beaker. 5. Place any leaves to be tested

Determining the Molar Mass of an Unidentified Volatile Liquid Abstract Molar mass helps to determine how much of a substance is present in a sample. Volatile liquids change from liquid to gas at relatively low temperatures and atmospheric pressures. In this investigation an unknown volatile liquid is vaporized so that the ideal gas law can be used to determine its molar mass. This study will apply the ideal gas law in tandem with the concept of volatile liquids and basic molar mass related stoichiometry

Hypothesis: The problem that is going to be answered is: will plant seeds grow at differently if they are covered by different materials while exposing them to the same amount of light? Also‚ which material will allow the plants to grow the most‚ tin foil‚ saran wrap‚ paper or no covering? Before the lab took place‚ it was hypothesized that the less light a plant receives‚ the less it will grow and the more light it receives‚ the more it will grow. The possible solution to this problem is to cover different
