A moving magnetic field causes an electric current to flow through conductive material. An electromagnetic sensor can be used to measure this induced electrical current.
Using Computational Thinking to Understand Earthquakes
Students build a seismograph to visualize earthquake data and explore modern engineering techniques used to mitigate earthquake damage. Then, they engage in an Excel big data activity to understand plate tectonics.
Harnessing Electricity to Communicate
Students build a telegraph out of everyday objects to understand electrical energy and its role in communications. Then, they use a customized workbook to send and receive information in Morse code using their telegraph.
