Wilting (Demonstration)
You should never put salad dressing (which is usually hypertonic to lettuce) on a salad that you want to eat several hours later. The demonstration below will show you why.
This is a demonstration, not an experiment. There is no hypothesis. You should take a picture for your lab report.
1. In a medium container, add 2 teaspoons of salt to 2 1/2 cups of distilled water and mix. Label the container.
2. Add plain distilled water to the second container and a layer of Italian dressing to the third. Remember to shake the dressing first. It isn't necessary to add a full 2 1/2 cups of dressing; use just enough to cover the lettuce leaf.
3. Add a fresh lettuce leaf to each container. Let sit one hour.
How do you explain what happened?
