brown banana So You Want to Do a Project about Oxidation!Let's ExplorePurposeTo determine if vitamin C can inhibit oxidation. Materials- banana
- dinner knife
- 2 saucers
- 2 sheets of white copy paper
- pen
- 3 vitamin C tablets (IOO-mg work well)
- cutting board
- rolling pin
- timer
- Peel the banana, and then slice it into eight pleces.
- Place four slices of banana in each saucer.
- Set each saucer on a sheet of paper. Label one of the papers ''Without Vitamin C." Label the other paper ''With Vitamin C."
- Place the vitamin C tablets on the cutting board and crush them with the rolling pin.
- Use the dinner knife to scoop up the vitamin C powder and sprinkle the powder over the cut surface of the banana slices in the With Vitamin C saucer.
- Every 15 minutes for 2 hours or more, observe the color of each sample's surface. Record your observation in an Oxidation Data table like the one shown.
- Repeat the investigation, adding a third test set of banana slices. Label the paper under the saucer ''With Lemon Juice."
- Use lemon juice squeezed from a fresh lemon.
- Photographs of the banana slices at the start, periodically during the test, and at the end of the test can be displayed to represent the progression of any changes. The photographs also help to compare the effectiveness of the antioxidants.
