First-grade scientists used their investigative skills to test what prevents an apple from turning brown. They sliced apples and put them in water, vinegar, lemon juice, nothing, baking soda and milk to see which worked best. According to teacher Nina Merkert, the students discovered that both milk and lemon juice worked. They were surprised that the milk worked since milk needs to be in refrigerator and they kept it on the table during the experiment.
