Using Your Senses, Third Edition

Students explore Using Your Senses through twelve hands-on activities and the Delta Science Reader. Introduce your students to the inner workings of the body's amazing communications network: the five senses. Students examine the structure of each sensory organ (eyes, ears, skin, nose, and tongue) to find out how it works. They use lenses and prisms to create images and colors, explore depth perception, and measure their fields of vision. They experiment with tuning forks, cones, and membranes to model sound waves and eardrums, and construct a zither for manipulation of pitch and volume. They distinguish textures by feel and test sensitivity to touch and temperature changes. Finally, they identify objects in odor boxes by smell and map the four taste areas of their tongues.

In the Delta Science Reader Using Your Senses, students read how our five senses: sight, hearing, touch, smell, and taste, take information from our surroundings and transmit it to the brain. The book also describes some of the ways a veterinarian uses her senses in her work. In addition, students explore the communication systems of Braille and American Sign Language.
