![]() Can you design a stabler tower? How tall can you build it before it loses stability? Try adding extra structural elements to your designs. Try comparing square designs to triangular or hexagonal designs. Good materials are straws, popsicle sticks or toothpicks and marshmallows. ![]() Extra: Try building towers out of a different material that allows you to test different structural designs.How do the towers' base-to-height ratios compare with how they perform on your shake table? Do you think that by changing the footprint you could make taller buildings more stable? You could also calculate the area of the base (by multiplying its length times its width in centimeters) and divide this by the height for each tower to get the ratio of base to height. Try testing LEGO towers with different-size bases. Extra: In this activity, you kept the footprint of each tower the same and only changed the height.If all of the towers fell, try testing this activity with shorter towers, a larger base that takes up more space and/or a smaller distance of shake-table displacement. Tip: If none of the towers fell, try testing this activity with taller towers and/or a smaller base size.Did all, none or some of the towers fall? If some fell and others did not, what were the differences in height between these towers? In general, did the taller towers fall more frequently than the shorter ones? To test each structure, create a lateral shaking movement using the same distance of displacement you previously measured. One at a time, starting with the shortest tower and progressing to the taller ones, secure each LEGO tower in the center of the shake table's top surface.What are the heights of the different towers? Use the same base size and shape for each tower, so that the size of the towers' footprints are the same, and only their heights vary. Build four or more LEGO towers of increasing height on a nearby surface. ![]()
