Students are introduced to raptors and their role in the environment. They identify three characteristics of raptors and list several types of raptors found in nature. They discuss their positive and negative experiences with raptors and...

Students discover why Fort Pickens was so valuable to both the Union and Confederacy, and follow the actions of the military commanders faced with crucial decisions. (National Park)

Students practice repeating rhythmic patterns in unison. Next, students work in groups to practice an alternate rhythmic pattern to Row, Row, Row Your Boat. They create their own rhythmic patterns for the song.

First graders compare and contrast rice plants with people. In this rice plant lesson, 1st graders discuss what make rice plants similar to people such as their bodies and coverings. They also discuss how they are different in what they...

Students learn the procedure for mixing secondary colors from primary pigments and observe the results of mixing two primary colors.

Pupils explore the concept of poetry through movement and song. They watch Lucille Clifton read her poem, and write their own poem.

Students learn about sound waves and use them to measure distances between objects. They explore how engineers incorporate ultrasound waves into medical sonogram devices and ocean sonar equipment. Students learn about properties, sources...

A discussion of refraction and its application to sound waves. Using analogies, graphics and real-life applications, this page and those that accompany it explain why and when sound waves bend.

Home page for a hypertext physics course. Users can access subjects ranging from the sound wave parameters that effect hearing and communication to OSHA worplace standards.

This page and the many pages which are indexed to focus on the behaviors of sound which characterize it as a wave. Reflection, refraction, interference, diffraction and more are clearly illustrated and explained.

Information about the interference of sound and its causes. Well-illustrated and good explanations of the concepts; part of a large hyper-textbook on various physics concepts.

Great animations showing how sound is produced.

This activity will use tuning forks and the CBR to gather sound wave data for students to use to write Sine (or Cosine) functions. In this activity we study waves of known musical notes before studying waves of unknown musical notes. I...

A physics tutorial on designing an auditorium and solving the problem of sound reflection. Illustrated.

This site's entry is a discussion of diffraction and its application to acoustics and acoustical design. Exceptional illustrations and great discussion throughout.

This lesson plan is designed to teach young children about how sound is heard in a three-step process using the Magic School Bus materials.

Online physics lab experiment in which students use resonating waves inside of a closed-end air column to determine the speed of sound. The form allows students to check their answers and receive immediate feedback.

An indexing page for an elaborate and in-depth hyper-textbook on various physics topics. This page indexes several others which pertain to human ability to perceive sound and recognize pitch. Introduces and explains Place Theory.

Homepage for a hypertext about the different families of musical instruments. From this page, users can retrieve information on a the acoustics of a variety of specific instruments: stringed instruments, woodwind instruments, brass...

A tutorial from a hypertext physics course book that discusses reverberation. Illustrated.

Home page for a hypertext physics course on auditorium acoustics and acoustical design.

This hypertext physics course tutorial on nonfocusing surfaces relates various design principles to good auditorium design. Illustrated.
