One of the labs for this module call for flower dissections. As we did the lab, I realized how easy it was to modify for all ages and still be a great learning experience!

Apples contain an enzyme called polyphenol oxidase (phenolase). When an apple is cut, the enzymes inside are released. Oxygen from the air causes phenolase to catalyse (speed
