Native American traditions reflect the story and struggle Native American’s experienced. These stories are filled with tradition closely tied to Mother Nature. I’m sure many of you have seen Native American art and objects‚ such as teepees‚ totem poles‚ and moccasins. These are articles that tied together Native American life. I’m going to share with you the meaning behind these symbols and traditions‚ and how they affect modern

scenario) For the side pole safety test‚ which is considered one of the most difficult to pass for cars‚ the Model S was the only car in the “good” category. Compared to the VolvoS60 which is also a five star rated in all categories. The model S has a 63.5 percent of driver residual space compared to the 7.8 percent of the Volvo. Tesla achieved this by putting a lot of deep aluminum extrusions in the side rail of the car which absorbs the impact energy. This causes the pole to be sheared off or to

With the similarity of being mostly ice‚ is how no two points on earth are the same‚ but unique in their own way‚ in being compared to another point on the earth‚ or not even existing until recently.

The cane and the fishing pole are symbols of the birch tree’s growth. “At first to be no bigger than a cane‚ / And then no bigger than a fishing pole‚” (ll 14-15) The cane and the fishing pole also represent the birch tree’s inevitable death. These man-made objects are made of wood‚ which are essentially dead trees. The speaker describes the

Universe and Inverse are closely related‚ for the effects of known forces of universe are inverse in nature. Ever since Newton made a bold proposition that there is a force of attraction amongst the planets of planetary system‚ amongst different planetary systems and amongst the different galaxies and varies as Inverse Square of their distances‚ people began to correlate every activities of nature and predict its effect accurately. 1.

I’m hoping to investigate how magnetism works through different types of substances. I chose two unique substances to test magnetism through: slime and wood. I hypothesize that magnets can still work through slime and that they can work through wood‚ but I hypothesize that they can’t work through both‚ because the magnetic field will be blocked too much. I designed five different set-ups to test how the magnets react in different ways using these materials. The results of the experiment proved four
