First we need to make sure we understand exactly what happens in the split & average steps.

Find out how we can make curved lines using straight ones using the string art construction.

What happens if the director changes their mind and asks for two headed robots?

First we'll review weighted averages of two points and extend the idea to three points. Practice weighted averages of two points in Environment Modeling if you haven't seen it before.

How can we calculate a weighted average between two points? (pssst. This video is super important).

This is a problem-based learning (PBL) group jigsaw activity. The scenario is:
Students are employees of a unit of the United Nations responsible for coordinating disaster relief after a major disaster (the 2004 Asian Earthquake and Tsunami) occurs. The agency needs to understand the situation in each country so that it can coordinate the work of various governments and nongovernmental organizations (NGOs) working in the affected area.

Students are divided into Expert Groups (related to academic specialties such as Economics, Medicine, Political Science, Earth Science, etc.) and spend several days researching their topics. Students are then reassigned to one of seven or eight Country Groups, based on the countries most affected by the disaster. Each country group needs someone representing each expert group. In the scenario, these groups correspond to task forces that must determine what the situation is in each country and try to assess the current need for international assistance.

Students research their country, using internet resources, especially the CIA World Factbook and ReliefWeb, the information coordination website of the United Nations. At a large-group roundtable discussion, each group presents what it has found about its assigned country. As a final product, each student writes an individual report summarizing findings and making recommendations for disaster assistance.

In this multi-part activity, students study seismograms from 3 different seismic stations recording the magnitude 9.0 Sumatra earthquake of December 26th, 2004. By comparing the arrival times of the P and S waves on each seismogram, students determine the distance from the epicenter to each station. Using that data, they can accurately map the location of the epicenter and the precise time of the earthquake. After locating the epicenter, students calculate the position of the tsunami generated by the quake at one hour intervals. From those determinations, predictions are made about how much time people had before the tsunami crashed onto their shores. Finally, students investigate some of the ways people can lessen the impact of the next great tsunami.

This report was the first of its kind to analyze the green job market in MI (3% of workforce) through an analytical (industrial and occupational trends), qualitative (focus groups), and quantitative (employer survey) approach. Discussed are Michigan's green related industries and occupations, and also tracking them. It's concluded that the MI green job market has further potential and is growing despite an economic downturn.

This activity uses data collected from DART (Deep-ocean Assessment and Reporting of Tsunamis) stations in the Pacific following the 2011 tsunami generated off the coast of Japan. Students are required to map the wave front after 5, 10, and 15 hours to better understand the speed and propagation of the tsunami wave.
