Product Description
This Physical Science Classroom activity enables students to investigate some of the details of seafloor spreading, including spreading rates and the signature of magnetic field reversals captured in seafloor rocks. The initial aim of the activity is to decipher a message hidden in the magnetic striping of the ocean floor. The message is written with a binary code of either north or south-pointing magnetic anomalies. Once students have deciphered the message, they answer questions about the age of the seafloor and its rate of formation.
