Pupils discuss sound and how it's measured, and through experimentation and implementation of the scientific method, they determine the speed of sound.

Pupils experiment with measuring the speed of sound in an open field by clapping hands and measuring the time delay between the clap and hearing the sound at a long distance. Students practice solving equations at completion of activity.

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

In this algebra worksheet, students apply the properties of logarithms. They solve word problems using the properties of logs and apply the formula for interest to solve money problems. There are 3 problems with an answer key.

Fourth graders study about sound waves and how they behave in various media. They create a soundproofed container. They explain that velocity describes a change in distance over time.

Students discuss conservation of energy using a skateboarder in the halfpipe or a person on a roller coaster as an example. Using mathematical equations, students examine potential and kinetic energy of the examples. Lesson is completed...

Seventh graders investigate the concept of looking at the data put in a variety of ways that could include graphs or data sets. They analyze data critically in order to formulate some sound conclusions based on real data. Students graph...

Students determine velocity using the slope of a time distance graph. They investigate a motion cart using a CBR unit and a TI 83 calculator setup. Using the graph generated, they calculate velocity.
