During science time, Maya placed two bean seeds in clear cups. She gave both seeds water and put them where they could get air. One cup sat near a sunny window, but the other cup stayed in a dark closet. After a week, the seed near the window grew a green stem and small leaves. The seed in the closet did not grow as well. Plants need sunlight, water, air, and enough space to grow. Roots absorb water from the soil and hold the plant in place. Leaves use sunlight to help the plant make food. Plants also need nutrients, which are helpful materials in the soil that support healthy growth. Maya measured the stems each day and wrote the changes in a class chart. She moved the second cup to the window and watched it begin to grow stronger.
