In AML we were inspired by the world record holder Brian Berg to build card houses. The project was to build 3 different kinds of card houses. The first was a cardhouse made out of triangle shapes. The second was built out of cubes. The last one was made out of whatever shape we wanted. The object of this project was to see how many coins the structure could hold on top of it. My second structure held about 200 coins on it.

Previously in the engineering section of applied math lab(A.M.L.) we have created tables created from newspaper, cardboard and tape. We quickly discovered that these are not the most powerful materials in the world. I learned that to make the most powerful table, we had to make very tightly rolled pieces of newspaper. My partner Abbey and I achieved the most tightly rolled newspaper in the class by folding it over itself over and over again. They ended out being much thinner than most of the other groups but held the best. Also, the structure was held by triangular shapes which are the strongest geometric shape. We were horrified however after creating our table that we were supposed to be measuring the amount of tape we used. We had to spend three classes finding out our tape usage. Fortunately, it all paid off. Our table easily held over nine pounds before collapsing. We were then allowed extra time to reinforce and re-test our table. We did, this time careful to measure and record the tape we were using. We have still not yet weighed how much it held then, but I think it held at least twice as much. This section of AML has been fun to learn and fascinating to experience.
8th grade students have been learning about the aspects of avalanches as well as safety and awareness (partly in preparation for the February snow camping trip). They simulated three different avalanche terrains on a flat board, and used flour, salt, sugar, and potato flakes to simulate varied snowpacks. As they increased the angle of the board, they measured the angle of incline as they observed what was happening to the different layers. They looked for slab and loose avalanches and reported at what angle they occurred as well as the distance of the slide. They used their data to derive generalizations about snowpack and incline in nature.
