Exploring Sensation and Perception: Understanding the Nervous and Endocrine Systems

This lesson focuses on sensation and perception, exploring how our senses receive and interpret information from the environment. Students will engage in group activities to formulate questions about the Nervous and Endocrine Systems, facilitating deeper understanding through collaboration. Key concepts include absolute and difference thresholds, sensory adaptation, and signal detection theory, as students analyze real-world examples related to vision and hearing. Throughout the lesson, students will apply critical thinking skills and create a summary to consolidate their learning.

Presentation Transcript

  1. Warm up • Using the provided sticky note, please write everything you know about sensation and perception and place on the corresponding board

  2. Enrichment • As a group, come up with 2 questions from each category about the Nervous System and Endocrine System. (You should have a total of 12 questions! We will switch these with another group in 10 minutes. • Remembering: define, duplicate, list, memorize, recall, repeat, reproduce state • Understanding: classify, describe, discuss, explain, identify, locate, recognize, report, select, translate, paraphrase • Applying: choose, demonstrate, dramatize, employ, illustrate, interpret, operate, schedule, sketch, solve, use, write. • Analyzing: appraise, compare, contrast, criticize, differentiate, discriminate, distinguish, examine, experiment, question, test. • Evaluating:, argue, defend, judge, select, support, value, evaluate • Creating: assemble, construct, create, design, develop, formulate, write.

  3. Quote of the Week! • “People see what they want to see and what people want to see never has anything to do with the truth.”

  5. Sensation • Process by which our sense organs receive information from the environment

  6. Perception • Process by which we select, organize, and interpret sensations

  7. How they work together

  8. In your groups… • Seat 1- Absolute Threshold (pg. 208-210) • Seat 2-Difference Threshold (pg. 210-211) • Seat 3-Sensory Adaption (pg. 211-212) • Seat 4-Signal Detection Theory(pg. 212-213) • Independently • 1- Read through your assigned section and article • 2-Analyze your concept- define the term, provide key details and examples (You should fill up the whole box!) • As a group • 1-VERBALLY share your findings with your group allowing all members a chance to share, as well as fill out their charts

  9. Create an Example! • Please create an example addressing all 4 concepts of sensation which we have just looked at. • You may focus on any sense • How are you going to determine the absolute threshold? Difference threshold? • How would sensory adaption play a role? • How would signal detection theory play a role?

  10. Warm Up • Sit with your 11 o clock partner • How do sensation and perception work together? • _______ ______ is the weakest amount of stimulus required to produce a sensation

  11. Sensory System Absolute Threshold Write down your best guess for each, then we will go through them!

  12. Vision • A lit candle ______ miles away on a dark, clear night

  13. Hearing • The tick of a watch _____ feet away in total quiet

  14. Smell • One drop of perfume dispersed throughout a ______ room apartment

  15. Taste • One teaspoon of sugar in ____ gallons of water

  16. Touch • The wing of a bee falling on your cheek from a height of _____ centimeter

  17. Absolute Threshold • http://www.garyfisk.com/anim/threshold.swf

  18. Difference Threshold

  19. Sensory Adaption • Complete the handout with your partner, we will take 10 minutes! • Group with the most ACCURATE examples will get candy 

  20. Sensation/Perception • Work with the senses.. • Today’s focus-->VISION & HEARING

  21. Vision • STEP ONE- Read Pages 215-218 with your partner ( Stop before hearing!) • STEP TWO- Label the different parts of the eyeball, underneath describe the process of how vision works • STEP THREE-Describe Electromagnetic Spectrum, Binocular Fusion, Color Deficiency, Retinal Disparity, Nearsighted and farsighted

  22. Inversion goggles • https://www.youtube.com/watch?v=RnxgJa5awS4

  23. Color Deficiency • http://www.youtube.com/watch?v=CWyrp3hu4KE

  24. Hearing • STEP ONE- Read 218-219 with your partner • STEP TWO- Labelthe parts of the ear (220) once again describing underneath how hearing works • STEP THREE- Describe auditory nerve, how loudness of sound is determined, and the two types of deafness

  25. WRAP UP • Please write a $2.00 summary of today’s lesson (words are .05 cents). You have 5 minutes to free write, then meet with your 7 o’clock appointment to share your summaries. Underline similarities you find between the two.
