Have kids use very blunt plastic knives to see what’s inside of an apple. Encourage them to identify the various layers of the apple. They may even want to draw a diagram of an apple to better explain what they found. Discuss the importance of seeds with children, as well as why they are hidden inside of a fruit. Make sure that they understand that trees grow from seeds, and that animals carry the fruit away to eat it, so that the seeds become more spread out. (In this way, the animals are a bit like Johnny Appleseed!)
