2nd Grade Science Activity: Richter Scale Activity
Charles Richter and Beno Gutenberg were seismologists in 1935. They both worked in California, the state that experiences the second most earthquakes of any US state, surpassed only by Alaska. The Richter Scale measures the amplitude of waves recorded by seismographs. For each whole number (1,2,3…) the magnitude of the earthquake is ten times greater. Earthquakes most frequently appear on or near fault lines.
This interactive activity is embedded in our Second Grade Science 2 course.
Students perform experiments to develop skills of observation and analysis, and learn how scientists understand the world. They demonstrate how pulleys lift heavy objects, make a temporary magnet and test its strength, and analyze the parts of a flower. Students will explore topics such as:
- Metric System-liters and kilograms, and how scientists use them
- Force-motion and simple machines; physicist Isaac Newton
- Magnetism-magnetic poles and fields; how a compass works
- Sound-how sounds are made; inventor Alexander Graham Bell
- Human Body-cells; the digestive system
- Geology-layers of the earth; kinds of rocks; weathering; geologist Florence Bascom
- Life Cycles-plants and animals
