Discuss plants and what they need. Ask students if all plants are alike, and what they require to grow. Show All About Plants to give students an understanding of plants and their needs.
After watching the video, talk about the types of plants featured. Do all plants look alike? What needs do plants have? How do they get their food? Discuss the parts of flowering plants and the process of photosynthesis, the process by which plants make food. Talk about plants that are familiar to the students. What do they look like? Where do they grow? What are their needs?
Have students choose a familiar flowering plant they would like to learn more about; tell them they will research and write a paragraph about it. Each paragraph should include the plant's common and scientific names; a description of the parts (seed, root, stem, leaves, and flower); its needs; and at least three interesting facts. Also have students draw a picture with each plant part labeled. Students may use encyclopedias, botany or gardening books, or magazines for research. The following Web sites also have useful information:
Allow time in class for students to research and complete their paragraphs and drawings. Then divide the class into groups of three or four so they can share their work. Ask them to discuss within their groups the differences and similarities of the plants.
Ask for volunteers to share what they learned from their research and group discussions. Review what students have learned about the needs of plants, the parts of flowering plants, and photosynthesis.
Definition: The bloom or blossom of a plant; the reproductive organ of an angiosperm plant
Context: Flowers come in all shapes, sizes, and colors.
Definition: The main organs of photosynthesis and transpiration in plants
Context: When you look at a forest in summer, you can see the green leaves of trees.
Definition: A process used by plants to convert water, carbon dioxide and sunlight into carbohydrates and oxygen
Context: Photosynthesis allows plants to make their own food.
Definition: The usually underground part of a seed plant body
Context: Roots hold the plant in place.
Definition: A fertilized and mature ovule containing a plant embryo
Context: A new plant will come from the seed.
Definition: Stalk; a slender or elongated structure that supports a plant
Context: The stem pokes up through the soil.
