During block days this week students are doing activities 6 and 7. First students will read activity 6 which explains the nervous system and touch receptors. While they read, the will take Cornell notes about the information that they are reading. The four main ideas in the reading are nervous system, nerves, eating food, and touch receptors. Next, students do activity 7 which is a touch test. The students test each other on their sensitivity to touch where they have to distinguish the difference between two points and one point. Students then analyze how human variation makes it difficult to study people.
