Atticus read an article about amyotrophic lateral sclerosis (Lou Gehrig's disease). This disease affects cells in the brain and spinal cord, making muscles weak and difficult to control. We viewed a diagram illustrating a normal nerve and muscle cell versus an ALS affected nerve and muscle cell. Atticus researched a well-known person who has been affected by ALS and wrote a short report telling this person's story, focusing on technologies that have helped this person deal with living with the disease.
