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...

Ahoy there! A fun computer science lesson challenges pupils to write a program that creates an ocean wave. They then develop stories to accompany their projects. All of this takes place within the Scratch coding program.

Students research the telegraph. In this telegraph instructional activity, students review the history of the telegraph. Students complete radio wave experiments. Students work in pairs to complete 3 sound exercises.

Learners examine the causes of tsunamis and observe a table top wave making machine. They make model houses while working in groups so that the can see how different construction types work. They discuss how engineers can design and...

Students examine how earthquakes, volcanoes, and landslides can trigger tsunami waves. They determine how engineers use sensors to detect the dangerous wave, and how they help design building that will survive the wave force and water.

Eighth graders build a structure that is able to withstand a simulated earthquake. They research earthquakes, earthquake measurement, and society's preparation for and reaction to them. Pupils build models and present them to the...
