Lesson Plan Date:12-9-04 Subject: Science/ Fourth Grade Text Reference: www.enchantedlearning.com and www.teachercreated.com Objective: COMPETENCY GOAL 1: The learner will make observations and conduct investigations to build an understanding of animal behavior and adaptation. By the end of the lesson the students will be able to label, with 80% accuracy, the basic anatomy of a butterfly, beetle, and fly, using the Internet as a resource. Description of Activities and Setting Materials and Supplies Time Activity 1. Focus and Review Ask review question on basic facts about Butterflies, beetles, and bugs that were covered earlier in a PowerPoint presentation. 3 min 2. Statement of Objectives Today class you will get to use the internet to help you learn about the body parts of Butterflies, Beetles, and Flies. Divide the class into 3 groups (Butterflies, Beetles, and flies). Give each student a handout on his or her corresponding group. 1 min 3. Teacher Input Worksheets and Computer w/ Internet access 5 min Worksheet and Computer w/ Internet access Encyclopedias, insect books and bug anatomy charts. 20 min Worksheets 10 –15 min Explain the project to the students, and review the Computer usage rules. Demonstrate how to follow the worksheet using a different insect, such as a bee, to provide an example. Have students begin the worksheet with their groups; however there can be no more than 2-3 students at the computer. Students who are not at the computer should be using classroom references to fill in the worksheet. I will circulate around the room. 5.Independent The groups get back together after the worksheets are finished. Each of the Practice groups will discuss what they learned. Then the groups will prepare a presentation of the material for the class 4. Guided Practice 6. Closure 7. Evaluation The groups will then present what they learned to the class and have the class fill in the worksheets on the insects they is presenting. Grade the worksheets Worksheets Modifications for Diverse Learners Learning Disabled: According to the individual students IEP the assignment will be adjusted. Extra time will be given. These students will be assigned a peer tutor if necessary. The student’s special needs will be considered in the grading process so that their grades will be modified according to their ability level. ESL Students: The assignment will be modified according to the student’s classroom modifications and English language proficiency. Students may be assigned a student translator buddy if necessary. The requirements will be reduced if necessary. The student’s language proficiency will be considered in the grading process so that their grades will be modified according to their ability level. 30 min Name_________________________________ Date__________________________ Butterflies, Beetles, and Flies Body Parts Worksheet Directions: Go to www.teachercreated.com/books/3408 and select pages 7…17. View What is an Insect, Insect Body Parts and Insects A-Z to help you label the different body parts of the insects. Butterflies Abdomen - The abdomen is the segmented tail area of an insect that contains the heart, Malpighian tubules, reproductive organs, and most of the digestive system. Antenna - An antenna is a sensory appendage that is attached to the head of adult insects. Antennae are used for the sense of smell and balance. Butterflies have two antennae with clubs at the end. Compound Eye - Insect compound eyes are made up of many hexagonal lenses. Fore wing - The fore wings are the two upper wings. Head - The head is the part of the insect that contains the brain, two compound eyes, the proboscis, and the pharynx (the start of the digestive system). The two antennae are attached to the head. Hind wing - The hind wings are the two lower wings. Leg - All adult butterflies have six legs. The two forelegs of some butterfly species are tiny. Proboscis - Adult butterflies sip nectar and other liquids using a spiral, straw-like proboscis located on their head. Thorax - The thorax is the body section between the head and the abdomen. The legs and wings attach to the thorax. Beetles abdomen - the segmented tail area of a beetle that contains the heart, reproductive organs, and most of the digestive system antenna - like all insects, beetles have 2 segmented antennae compound eye - a faceted eye made up of many hexagonal lenses elytron - (plural elytra) elytra are hardened fore wings that protect the longer hind wings head - the head is at the front end of the beetle's body and is the location of the brain, the two compound eyes, the mouth parts, the pharynx (the start of the digestive system), and the points of attachment of its two antennae. hind wing - beetles have two hind wings, used for flying (or swimming). These long wings can be folded under the elytra when not in use. legs - like all insects, beetles have 6 jointed legs mandibles - the jaws maxillary palps - long, segmented mouth parts that grasp the food thorax - the middle area of the beetle's body - where the legs and wings are attached Flies Abdomen- the segmented tail area of a fly that contains the heart, the reproductive organs and most of the digestive system. It also contains the spiracles. Antenna- like all insects, flies have two antenna, which are used to warn of danger and to find food. Compound eye-flies have two large eyes made up of thousands of six-sided lenses. Transparent wings- flies have wings that are so thin the veins show through. They are used for flying. Halters-rod like parts that give the fly a sense of balance. (This is what a fly has instead of hind wings). Head- Found in front of the fly’s body it contains the brain, compound eyes, the proboscis and the pharynx (the beginning of the digestive system). Legs-flies have six legs. Their legs have end claws that help them cling to various surfaces. Proboscis- flies use this tube like structure as a straw to drink its food. Thorax- The thorax is the body section that is between the head and the abdomen. The legs and the wings are attached to the thorax. Spiracles- The air holes that the fly breathes through. The abdomen contains eight pairs and the thorax contains two pairs. Sponging Mouthparts- These are found at the end of the proboscis. They are used to lap up the liquid foods flies eat.
