Teach Engineering: Control Using Sound

Sound engineers investigate the structural design of a musical instrument, the recorder. They work in collaborative groups to choose an instrument to build out of everyday craft materials. It must be able to repeat a three-note sequence...

Tap into the desire to learn about computer codes. Pupils apply the Tap Code and the Polybius Square to send secret codes using sound. They design a code that tells a robot what movements to make and then test out their code using one of...

The marine environment is unique and requires technologies that can use sound to gather information since there is little light underwater. In this instructional activity, the students will be shown benthic habitat images produced by...

Students investigate the materials properties-such as acoustical absorptivity, light reflectivity, thermal conductivity, hardness, and water resistancea-of various materials. They use sound, light and temperature sensors to collect data...

In this activity, students will review and evaluate the ways land is covered and used in their local community. They will also consider the environmental effects of the different types of land use. Students will act as community planning...

By studying key processes in the carbon cycle, such as photosynthesis, composting, and anaerobic digestion, students learn how nature and engineers biorecycle carbon.

Students learn the connections between the science of sound waves and engineering design for sound environments. Through three lessons, students come to better understand sound waves, including how they change with distance, travel...

Students learn about the mechanical advantage offered by pulleys in an interactive and game-like manner. By virtue of the activity's mechatronic presentation, they learn to study a mechanical system not as a static image, but rather as a...

The marine environment is unique and requires technologies that can use sound to gather information since there is little light underwater. The seafloor is characterized using underwater sound and acoustical systems. Current...

Students discover how engineers can use biomimicry to enhance their designs. They learn how careful observation of nature can lead to new innovations and products. In this activity, students reverse engineer a flower to glean design...
