Stimulus and Response Worksheet 2 with Answers
- 1. Science Focused Learning Lessons 187 Focused Learning Lesson Science Grades 9-12 LS-H-F3 Overview: This lesson is designed to review how behavior is the response to stimuli by an organism. The teacher will review the definitions of stimuli, response, and behavior; give examples of stimuli, responses, and behaviors; and then provide exercises for the student to practice recognition of stimuli, responses, and behaviors. The worksheets are provided along with answers to the worksheets. Approximate Duration: 45 minutes. Benchmark: LS-H-F3 recognizing that behavior is the response of an organism to internal changes and/or external stimuli. Biology GLE: 35. Explain how selected organisms respond to a variety of stimuli. Benchmark: SI-H-A2 designing and conducting scientific investigations SI GLE: 2. Describe how investigations can be observation, description, literature survey, classification, or experimentation. Objectives: 1. The student will define stimuli, response, and behavior. 2. The student will identify and give examples of stimuli and responses. Teacher Preparation: 1. The teacher should review Attachment 2: Key. 2. The teacher should make a copy of the worksheets (Attachment 1) for each student. (Optional: Teacher can make transparencies to project) 3. Divide the class into groups of two to four for group work and presentation. Materials: • Worksheets for each student (recommended) • Pencil or pen • Scissors (optional) • Glue or tape or stapler (optional) Lesson Procedures: Set or Opener: Ask the students “Why do most dogs chase cats?” List students’ answers on the board. Allow about 5 minutes or until there are no more answers. If available, the teacher might show a short video clip of unusual animal behavior and ask students to analyze the behavior for cause and effect. Body of the Lesson: 1. Write on the board or a transparency, “Behaviors of living organisms are

List the different answers of the board or a transparency. 3. When an agreement is reached, give each student the first page of the worksheets, Attachment 1, and have the students copy the basic principle from the board and their answers to the definitions in the space provided in Part 1 of the worksheet. 4. Have the students read the examples of the descriptions in the list in part two and have them provide their own examples in the space provided. 5. Have students classify the list of events in part three as stimuli or response individually. 6. Give each student pages two and three of Attachment 1, worksheets. Read and explain the directions. The students may write in the answers or may cut out the appropriate answers and paste, staple, or glue the matching events in the proper place according to the choice of the teacher. Allow each group to work about 15 minutes. 7. Go over the answers either using a transparency or allowing one student from each group to present an answer, going from one group to another. Discuss any disagreements. Closure: Repeat the basic principles again. Give the students an example of a stimulus (not mentioned in the exercise) and have them give possible responses or behaviors to that stimulus. Optional: Give a short three-question quiz. Attachments: Attachment 1: Student Worksheets (three pages) Attachment 2: Key Sample Assessment Items: Page two of the student worksheets may be used as an assessment. Reference Links: N/A

- 6. Science Focused Learning Lessons 192 Attachment 2: Stimuli, Response, and Behavior Worksheet Page 1: KEY PART 1: Fill in the following blanks. 1. Basic Principle The behavior of living organisms are responses to some internal or external stimuli. 2. A stimulus is any kind of detectable signal external or internal that carries information that requires a response. 3. A response is any single, specific reaction to a stimulus of an organism. 4. A behavior is the way an organism reacts to changes or needs in its internal condition or external environment. 5. A behavior can be innate which means it appears in a fully functional form from the first time it is performed, instinct or a behavior can be learned which means it is acquired from experience. PART 2: Following is a list of common stimuli and responses. Give 3 more examples of each. Stimuli Response Bright Light in eyes of person (external) Put on sunglasses Hunger pains in stomach (internal ) Eat food Strange person enters yard of dog (external) Dog barks or growls PART 3: Label the following events as Stimulus or Response. 1. Shark swims toward the direction he smells blood. Response 2. Plant grows toward the direction of the sunlight. Response 3. A bat hears the flapping wings of an insect. Stimulus 4. A person feels the heat of a hot stove. Stimulus 5. A dog chases a running rabbit. Response Answer will vary.
