Material Required: Apple, knife, plate, orange, banana,
Procedure:
1. Cut all the fruits one by one and put them in a plate.
2. Half of them put in another plate and cover them.
3. Now observe what happens in both the plates (covered and uncovered) and record your
observation.
4. Find out the reason behind it if change occurs in both the plates or in one plate.
5. Write your observation about one page in the A4 sheet.

Answer:
Explanation:
Fruits that were covered will be fresh, while those that weren't had brown spots all over them.
Oxidation, a process, caused the black or brown spots to appear. A specific chemical (enzyme) known as polyphenol oxidase is released and interacts with the oxygen in the air. When exposed to air, a certain enzyme found in fruits reacts and produces brown patches.
Oxidation definition:
Initially, the word "oxidation" was used to refer to chemical processes in which an element reacts with oxygen. An illustration of this is the oxidation of magnesium in the formation of magnesium oxide when magnesium metal and oxygen react.
Polyphenol oxidase definition:
A class of copper-containing enzymes known as polyphenol oxidases (PPOs) catalyzes the oxidation of o-diphenols to quinones (catalase activity) and the o-hydroxylation of monophenols to o-diphenols (tyrosinase activity).
Enzyme definition:
Proteins called enzymes aid in accelerating our bodies' chemical reactions, or metabolism. Some compounds are created, while others are broken down. Enzymes are a part of all living things. Our bodies create enzymes on their own.
