Provides acoustical background necessary to understand the role of sound in speech communication. Analyzes constraints imposed by the properties of sound and human anatomy on speech production (sound production from airflow and filtering by the vocal tract); auditory physiology (transformation of acoustical waves in the air to mechanical vibrations of cochlear structures); and sound perception (spatial hearing, masking, and auditory frequency selectivity). The Acoustics of Speech and Hearing is an H-Level graduate course that reviews the physical processes involved in the production, propagation and reception of human speech. Particular attention is paid to how the acoustics and mechanics of the speech and auditory system define what sounds we are capable of producing and what sounds we can sense. Areas of discussion include: 1. the acoustic cues used in determining the direction of a sound source, 2. the acoustic and mechanical mechanisms involved in speech production and 3. the acoustic and mechanical mechanism used to transduce and analyze sounds in the ear
Test your knowledge of the digestive, respiratory, and other human body systems in this interactive game from Kinetic City. Race the clock to put Arnold's organs back into his body one system at a time.
Becoming Human is an interactive documentary experience that tells the story of human origins. Multimedia, research and scholarship are presented to promote greater understanding of the course of human evolution. This site includes classroom materials, subject-designed exercises, games and activities to help make connections between the concepts that are presented and student learning. PDF versions of the resources may be downloaded from the site.
Part of the circulatory system is composed of a series of tubes carries the vital elements and the wastes that keep us strong and healthy. Take a look at these amazing vessels and how they work together.
Did you ever wonder why a camel has a hump? If you can really tell the weather by listening to the chirp of a cricket? Or why our joints make popping sounds? These questions deal with everyday phenomena that we often take for granted, but each can be explained scientifically. Everyday Mysteries will help you get the answers to these and many other of life's most interesting questions through scientific inquiry. In addition, we will introduce you to the Library of Congress' rich collections in science and technology.
You should always stretch before performing any kind of exercise. Warming up the muscles by stretching them lowers the risk of injury. Jumping right into exercise could hurt your body permanently.
For thousands of years the inner workings of the body have provoked fascination, confusion, amazement and even disgust. This site looks at the way different cultures, at various points in history, have looked at the body, and how these ideas have been translated into pictures.
In this teacher developed Design Challenge unit, students learn about the systems of the human body by creating a "museum exhibit" for their classroom. Download with the California State Science Standards.

Hinge joints move only in one direction, ball-and-socket joints are free to rotate in all directions, and gliding joints are able to move forward, backward, and side to side, but do not rotate freely.
Molecules of odor travel from their source up into our noses. The molecules travel up into the olfactory area. The molecules dissolve into a mucous membrane there and nerves carry the information taken from the molecule to the brain. We perceive a distinct smell after this process.
This site explores the brain and nervous system. Learn about brain development, brain lobes, the cerebral cortex, the skull, blood supply, brain fitness, neurons, the autonomic nervous system, sensory systems, the spinal cord, laughter and the brain, the musical brain, face recognition, drug effects, neurological and mental disorders, and more.
The NIH curriculum supplements are teacher’s guides to two weeks of lessons on the science behind selected health topics. They combine cutting-edge biomedical discoveries with state-of-the-art instructional practices. The NIH curriculum supplements are now aligned to state education standards in science, mathematics, English language arts, and health. This State Standards Web page allows you to find which standards are met by a specific supplement and vice versa.

This online science magazine features the latest news in science, math and technology. The Why Files has resources for teachers. This page classifies stories by grade and science standards.
The Anatomy Cookbook has been written to accompany an anatomy and physiology course for bioengineers who would otherwise have missed out on the opportunity to study real organ systems at first hand. It is not an alternative to a standard anatomy text, it acts more as a laboratory supplement. The fun bit is that your kitchen takes the place of the dissection room. Each recipe provides an insight into one or more organs, and all you need to do is go to the supermarket and be prepared to think about your food in a radically different way.
