Daily Lesson Plan Student: Kimberlee Haldane Subject: Science Cooperating Teacher’s Approval: Topic: Classifying Flowers: Lesson One- Labeling the Flower Date: 10-29-11 Grade: 7 Allocated Time: 80 Minutes Student Population: A 7th grade Heterogeneous group comprised of 24 male and female students of various educational levels including 3 students with IEP’s, 2 ESOL students from Columbia and 1 hearing impaired student. Description: This is the first lesson on classification in a science classroom. This lesson introduces the student to plant classification and prepares them for the final goal of classifying all the flowers in the school garden. This lesson will be the first page of a handbook students will complete in this unit. The handbook and all other materials will be featured in the school library as a reference guide. All 3D flowers will be sold to raise money for our class trip to the Botanical Gardens. The lesson also provides material the different parts and functions of a flower to help the classification process. State Standards: 3.1.7.A1: Describe the similarities and differences of physical characteristics in diverse organisms. S7.A.3.1: Explain the parts of a simple system, their roles, and their relationships to the system as a whole. S7.A.1.1: Explain, interpret, and apply scientific, environmental, or technological knowledge presented in a variety of formats (visuals, scenarios, graphs). S7.A.1.1.4: Use evidence to develop descriptions, explanations, and models. Unit Goal: At the end of the unit SWBAT create a handbook, classifying all the different types of flowers found in the school garden. Lesson Goal: Students will be able to create origami flowers to raise money for a trip to the botanical gardens. Measureable Objective: SWBAT label the different parts of a flower through lecture and note taking SWBAT show different classifications of flowers by creating origami replicas Student Behaviors Sources of Evidence Criteria for Evaluation Labeling of the different parts of a flower through lecture and note taking KWL Worksheet (See Demonstration of strong note attachment #1) taking skills Worksheet: diagram of parts of a flower, to be completed with teacher (see attachment #2) Show different classifications of flowers by creating origami replicas Origami instruction sheet (See attachment #3) Rubric (See attachment #4) Background Information: Classification: A method to group and categorize organisms by biological type, such as genus or species. Classification of Plants and Animals At any one time in history, there are millions of different kinds of plants and animals in the world. In 1753, a scientist in Sweden named Carolus Linnaeus thought of an orderly system for classifying plants and animals. He grouped all organisms according to a two-part name (binomial). The first part of the name is the "generic" grouping or genus. The second part is the "specific" grouping or species. Scientists today still use this basic idea of his system, but modern classifications systems are much more complicated having many levels of hierarchical organization. For example, taxonomic systems group organisms according to structure and physiological connections between organisms. Phylogenic systems classify based on genetic connections. Evolution theories have impacted modern classification. In order to begin to classify plants, consider the structure by which the plant absorbs water. Plants are either vascular or non-vascular. Vascular plants have tube-like structures that transport water from the roots to the stem to the leaves. Non-vascular plants absorb water only through their surfaces. Heirarchy of Classification Kingdom Plantae Plantae Division Anthophyta Anthophyta Class Dicotyledones Monocotyledones Family Boraginaceae Liliaceae Genus Mertensia Scilla Specific epithet virginica non- scripta Common name Virginia bluebell (Example) English Bluebell Alternation of Generations Alternation of generations occurs throughout the plant kingdom right through to flowering plants and it is impossible to understand plant reproduction without grasping this concept. Some algae show this feature particularly well. For example in Ulva lactuca (Sea lettuce) the haploid and diploid generations are well developed and look identical until they produce gametes or spores, respectively: Life cycle of Ulva lactuca The flower parts: Flower part Petal Stigma Style Ovary Ovule Receptacle Flower stalk Nectary Sepal Filament Anther Part function Petals are used to attract insects into the flower, they may have guidelines on them and be scented. Is covered in a sticky substance that the pollen grains will adhere to. The style raises the stigma away from the Ovary to decrease the likelihood of pollen contamination. It varies in length. This protects the ovule and once fertilisation has taken place it will become the fruit. The Ovule is like the egg in animals and once fertilisation has taken place will become the seed. This is the flower's attachment to the stalk and in some cases becomes part of the fruit after fertilisation e.g. strawberry. Gives support to the flower and elevates the flower for the insects. This is where a sugary solution called nectar is held to attract insects. Sepals protect the flower whilst the flower is developing from a bud. This is the stalk of the Anther. The Anthers contain pollen sacs. The sacs release pollen on to the outside of the anthers that brush against insects on entering the flowers. The pollen once deposited on the insect is transferred to the stigma of another flower or the same flower. The ovule is then able to be fertilised. Please note: The stigma, style, ovary, and ovule are often known collectively as the carpel or female parts of the flower. The filament and the Anthers are collectively known as the Stamen or the male parts of the plant. Origami Lily Please see attachment for origami guide. Estimated Time: 5 minutes Teaching to the Objective Differentiation: Warm Up: ESOL students will be given instructions in English and Spanish. Students will be given a KWL charts upon entering the classroom. On the Board: DO NOW- Complete the KWL chart for the Lily and the Rose. List everything you know about Lilies and Roses and everything you would like to know about them. Teacher will ask for volunteers to share what they have written. 15 minutes Introduction: The introduction will be made Students will be introduced to the into a powerpoint using lots of idea of classification. visual aids . Teacher will write definition on board for students to copy. Teacher will lead a discussion on why we classify things and what types of things we classify. Teacher will lead students to identifying how things are classified. Introduction to flower classification. Show a diagram of a flower on Whiteboard and have students try to identify the different parts. (Expect answers like: petals, stem, seeds, leaf) Ask class: Why would we classify flowers? Ask class: “Do you know how many types of flowers we grow in our school garden?” Show students a picture of a rose and lily side by side. Explain that the answers given by the students can be used to identify both flowers. 25 minutes Development: Explain that we are going to spend the unit understanding plant and animal classification and that we are going to help ourselves understand classification by identifying all the types of flowers we grow in the school garden. We are going to create handbooks after we have finished classifying all the flowers in the garden and these handbooks will be filled with illustrations and facts and placed in the library as a reference tool. 25 minutes Show students a book on plant classification so they might have an idea of how their end products will look and what types of information it will give. Lead class back into discussion of the different parts of flowers. Ask: “Why might I need to know the different parts of a flower?” Each student will be given a diagram of the parts of a flower. Students will take notes on the various parts of a flower. (Teacher will explain each part then give time to copy notes on the board. This process will be explained and modeled for the students.) Developmental Activities: Students will be told of trip to the Botanical Gardens and how we can raise money for the trip. Teacher will explain that students will create origami replicas of the each flower they classify in class beginning with the Lily and the Rose. Students will construct an origami lily Each student will receive an instruction sheet and a piece of color paper. The teacher will play the instructional video once through for the class. The teacher will restart the video stopping after each Students will be given origami instructions in Spanish and a video detailing the instructions for the lily will be shown instruction to model the procedure. Assessment: KWL worksheets, class notes, origami Lilly 10 minutes (5 minutes to answer questions Closure: and 5 minutes to discuss answers) Exit TicketStudents will fill in the L on their KWL charts. “What did you learn about Roses and Lilies today?” Answer the following question: Using what you have learned today, how might I use classification to help me plant the perfect garden if I lived in Florida? Follow-up: Students will complete a Jigsaw in which they re-teach each other the different parts of a flower.
