Student imitate mapping the ocean floor using the basic concepts of radar. Then they explain what radar is and how it workds. All of their measurements are recorded on a data sheet. Then the data is entered into a spreadsheet program. A...

How do you create a map of the ocean floor without getting wet? Middle school oceanographers discover the process of bathymetric mapping in the third installment in a five-part series of lessons designed for seventh and eighth graders....

A brief animation introduces heredity to your beginning biologists. They will meet Gregor Mendel's green and yellow peas, dominant and recessive traits, homozygous and heterozygous alleles, and Punnett squares. In this cartoon animation,...

Using a karaoke machine, a guitar, and other devices, learners explore the way sound waves travel. Using this hands on approach, learners can get a better understanding of wavelength, frequency, and more.

Students are told that sound is not just stuff that our ears hear. They are explained that it is a tool for measuring and looking at objects in a new way. Students are introduced to sound waves and sonar imaging. They are explained...

Eighth graders participate in an experiment that emulates a sonar signal bouncing off the ocean floor. They determine how the ocean floor is measured by the length of time it takes for the sonar signal to return. They work with a wooden...

Young scholars demonstrate how energy is used to make a sound. In this sound lesson, students construct a kazoo from a comb and identify how a sound is made by using force.

Students investigate the relationship between pitches and notes. In this musical pitches and notes lesson, students use different sized bottles, water, and sugar to demonstrate different sounds. Students create musical notes.
