How big was that earthquake? The worksheet is a measuring activity where students must precisely measure the height of peaks on a seismogram and correlate this measurement to the Richter scale value of the earthquake. Accuracy counts! The answer key is provided.

This packet also provides the student sheet for a bar graph that plots the most powerful earthquakes ever recorded in the world. Graph paper is included.

Finally, a 15 clue crossword puzzle is included that comes with and without a word bank, which allows you to differentiate the assignment.

    Dr. David PurvisAfter obtaining a PhD in Microbiology, I switched careers and became a middle school and elementary science teacher because I loved kids. Almost thirty years later I have taught science in some context to every grade level from pre-K to college education classes. My store offers rigorous resources that align meaningful content, an inquiry approach, NGSS standards, and student interest.
