Making Sense of our Senses
Description: Have you ever wondered how we sense things? This unit is all about the brain and how the nervous system works. Find out what “extra” senses exist in the animal kingdom, and how much better some animals’ senses are than those of humans. We will also explore the connection between taste and smell, discover how optical illusions fool our brain, and learn why we have two eyes and ears instead of only one.
