“Children, yesterday on my way home, I saw a little girl named Teni. She planted a small bean seed in a cup. Every morning she watered it. After some days, the bean plant grew tall and green. Do you know what helped the seed grow? Yes—the soil! Soil is like a soft bed that plants sleep in, eat from, and grow inside. Today, we will find out more about soil and why it is so important.”
