Objective: The children will learn the basic parts of plants (roots, stems, leaves, flowers, and seeds) and the function of each part.
Plants are living things that need water, light, nutrients, and air to grow. Each part of a plant has a specific function that helps the plant grow. Roots provide the foundation for the plant and also absorb and store water and nutrients from the soil. The stem of the plant gives the plant strength to grow upright. It also delivers nutrients and water from the roots to the leaves and carries the food produced by the leaves to the rest of the plant. Leaves collect sunlight to make food; this is called photosynthesis. Flowers, typically found on the end of a stem, are responsible for reproduction. Seeds and pollen are produced in the flowers. The seeds have the potential to become baby plants. The seeds can grow leaves, roots, stems, flowers, and more seeds.
Plants are different from other living things because they make their own food. Energy from sunlight is used by the plant to make its food. This is called photosynthesis. Plants use carbon dioxide and make oxygen, which animals and people need to breathe. Oxygen exits the plant through tiny holes in the leaves. Green plants provide most of the oxygen for other living things.
These lessons are aligned with the Common Core State Standards ("CCSS"). The CCSS provide a consistent, clear understanding of the concepts and skills children are expected to learn and guide teachers to provide their students with opportunities to gain these important skills and foundational knowledge.
