Lesson Plan – Human Anatomy Carter Payne Grade/Subject: 7th Grade, Life Science Unit: Human Anatomy, the brain Title of Lesson: The Collective Brain Intended Learning Outcomes: At the end of the lesson, students should be able to: 1) Create models of neurons, axons, and a neuron network 2) Describe the function of a neuron and the ways in which neurons are connected to form a network TIME LESSON CONTENT MATERIALS 0 – 10 min I. Orientation [Note-Taking] (see attachment #1) - Students label diagram of a neuron, writing a one sentence definitio n of each part using their textbook 10 – 20 min II. Development[ Mini – Lecture] - Teacher dresses as a neuron – use fabric strips as myelin sheath on one arm (axon). Review vocab. From intro, relating labels on diagram to parts of the “human neuron” model. Invite two students to front of class (noting gender and ethnicity) to make a synapse. 20 – 30 min III. Activity [Interpretive Model] - All students are given fabric myelin and are invited to synapse with their neighbor. Next, each student is challenged to make two connections. Students write who has connected to their axon and who has connected to their dendrites. 30 – 50 min - [Construct Models] – Teachers demonstrates how to make a neuron model using pipe cleaners and Styrofoam. - Students build model neurons - Students are challenged to connect their model neurons in the same order that they were connected as human models to make a class brain. 50 – 60 min IV. Closure [Exit-Slip] - Students write a few quick sentences describing the function of a neuron and how those neurons function as a network. Attachment #1 Teacher Material Sheet Human Nerve Cells - 35 strips (6 cm wide, 1m long) of fabric Pipe Cleaner Nerve Cell Models • Large box Styrofoam packing material • 70 full length pipe cleaners (30 cm) • 30 pipe cleaners, cut into fourths (~8cm) • 15 drinking straws – cut in half • fishing line to hang neuron network at the end of class Background Information Discuss with students the contributions made by varying scientists concerning neuron and neuron network research. In particular ment ion, the Venezuelan biologist Humberto Fernandez-Moran who discovered the myelin sheath and its role in carrying impulses along the neuron. Also, many ancient cultures of Assyria and India made discoveries about the spinal cord and an understanding of the causes of paralysis.
