Today, My class was split into groups to build a structure out of newspaper and tape only. My group had very different ideas at first , but later we came into consensus that first we should make the structure's base as a shape of triangle. As we all know, triangle is the most stable geometric shape out of all shapes. One of the group members suggested to roll the newspaper to very thin and strong rolls, this can extend the length of the newspaper and also make the rolled newspapers stronger. When we used most of our newspapers to make rolls one of the problem because clear and that was when we are connecting the rolls, the connecting part seems to bend, to solve this problem, we had to cut the two edges of each of the rolls made up of newspapers and insert one into the other and tape it. When the three long rolls of newspaper were taped to the triangle base that we made previously, the rolls could not stand straight, this was because first it was too long, second it was too thin. Therefore, we inserted another triangle in the middle of the structure to additionally stabilize the structure. The outcome of the structure my group made was very successful, unfortunately we did not build the tallest, but it was close. The main physics applied in building a structure would be gravity (a force attracts the body towards the center of the earth.)

The Earth has a magnetic field, because iron and metal that are located at the outer core. When people first invented the compass, they named the north end "North" and named the south end "South" based on the direction the needle on the compass is pointing to. Later, people discovered that the North pole set by the compass is actually the South pole. This is because of magnetic, the same poles always repel from each other, but opposite poles attract each other. The compass is made of magnets, the needle is also pulled toward the opposite end, so the North on the compass is actually the South in magnetic pole and South on the compass is the North in magnetic pole. Therefore Santa is from the South pole not the North pole.
