SILVERDALE-Science teacher Bob Detweiler challenged his eighth grade students to build earthquake-proof structures. Students were only able to use straws, pins, paper clips, and a cardboard square as the base. Students, who worked in groups of four, were required to build a second story. Detweiler built an earthquake simulator that used a drill to create a vibration. Some groups made their structure look like a triangle and some made their structure look like a square. On the day students tested their structures they had to put sandbags on the structure, answers questions, and draw pictures to match the structure. Students put sandbags on their structures to test if they sturdy before seeing if they could withstand an earthquake. Only a couple of groups in one class could hold one sandbag on their structures. One group held up to five sandbags and tested to see if would withstand a big earthquake; and during the earthquake their structure fell over, but they held the largest amount of sandbags. |
