Fourth grade students got a special visit from Ajax, a special dog that works with The Utah County Sheriff's Department. In science, the 4th graders have been learning about how animals receive and process information from their environment using their senses. We were able to see how Ajax has been trained to help police officers by using his highly developed sense of smell. We learned that dogs like Ajax have 300 million scent receptors in their noses compared to the 400 scent receptors that humans have! It was fun to see how Ajax was trained to work and to learn more about the special job he does as a police dog.
