Alexa and I began reading the novel. We discussed the setting of the book. I showed her pictures of the mansion in the book from Alfred Hitchcock's movie of the novel. We began to discuss the characters, especially the protagonist who narrates the story. Alexa will read more of the book for homework.
Define and discuss stimulus and receptor. Stimulus must be of a minimum level required to produce a transmission in a nerve. The nerve responds according to the "all or none" principle. Define nerve "firing" and review the polarization-depolarization of nerve transmission
Alexa is working on her drawings between our classes. She's very dedicated to her work and thinking of new ways to make new patterns.
We also have fun talking about a variety of things. We both love dogs. Sometimes my cocker sits in a chair and watches. Today she brought in her Coton to show me.
Start with a discussion of different types of sensory receptors, including pressure, pain, touch, hot, cold, taste, vision. The receptors are specialized to be stimulated by specific stimuli. The transmission is through a sensory nerve, composed of sensory neurons, to the central nervous system. The brain then interprets the type of sensation and the location. A response to the sensory transmission is through the action of a motor nerve, leading to a muscle or gland which responds by contracting or secreting. Examples of some stimuli and responses were given. The nature of the nerve transmission was discussed in terms of ion charges surrounding the cell membrane, polarization, depolarization, and re-polarization.

Lesson Comments
Alexa does much better with only 1 hour/day rather than 2, even though the hours were separated by lunch.
"The Lottery" by Shirley Jackson and "The Monkey's Paw" by W.W.Jacobs
Lesson Outline
Today Alexa and I read the short story "The Lottery." We discussed it's dystopian theme and content. We answered some accompanying study guide discussion questions. We also began reading another short story"The Monkey's Paw". We ran out of time, and Alexa will read the majority of that story for homework.
The synapse between nerve cells was seen on images. How the synapse functions to secrete neurotransmitters, and how these chemicals stimulate the next neuron to fire and transmit an impulse was explained and viewed on a video. The chemistry of ions was brought up at this time so that the transmission of the nerve impulse through the neuron by depolarization and re-polarization could be looked at next.
