Unit 2: The Changing Earth Module: Natural Hazards
Lesson Outline
Lesson 1: Earthquake Risks – Dutch learned which areas are at high risk for earthquakes. The Western states in the United States are at highest risk. California has a transform plate boundary and there is a convergent plate boundary in Oregon, Washington, and Alaska. Then he learned that some parts of central and eastern United States have a higher earthquake risk because they have had them before. Next he learned that scientists can tell you the likelihood of an area experiencing an earthquake but they can’t tell you exactly when it will happen. Next he learned that to reduce the impact of earthquakes, buildings can be designed to withstand the shaking that occurs.
Assignment: Add picture of frequency of earthquakes in US to science notebook.
Dutch continued an exercise from the 7th grade math Envision textbook, Solving Equations Using Subtraction. He also practiced several multiplication facts.
We discussed current conditions in the cryptocurrency, real estate, stock, and bond markets. Discussions today were centered around what affects market prices.

Lesson Comments
Dutch does not have significant interest in financial markets but he did bring up his charter fishing idea and where he should set it up. He is considering the Bahamas or Key West.
Unit 2: The Changing Earth Module: Natural Hazards
Lesson Outline
Lesson 1: Earthquake Risks – Dutch learned how earthquakes are measured. The Richter scale is a numerical rating system that measures the energy of the largest seismic waves produced by an earthquake which are measured with a seismograph. This scale uses the amount of ground motion at a given distance from an earthquake to determine magnitude. Each increase of one unit on the Richter scale represents 10 times the amount of ground motion. Then he learned about the moment magnitude scale which is a rating scale that measures the energy released by an earthquake, taking into account the size of a fault, the motion along the fault, and the strength of the rocks that break during an earthquake. This scale uses newer technology to produce more accurate measurements. The modified Mercalli scale measures the intensity of an earthquake based on descriptions of its effects on people and structures. This scale ranges from I to XII. Then he learned that the epicenter is the point on Earth’s surface directly above where the energy from an earthquake is first released.
Assignment: Add pictures of seismograph and comparison of Richter, Mercalli, and Moment Magnitude Scales to measure earthquakes to science notebook.
I pulled out Dutch's display case and asked him what he would like to place, on the outside, of the case. He informed me that he would like to do a sunset. We used a series of paints to achieve the sunset look that he had envisioned.
