Engineering Design, Bobsled Activity

My bobsled was supposed to be fast.  I had a a material under my bobsled that didn't allow it to slide well so i should have removed that. Also i should have put all the weight in the front instead of the back.

Fantastic Forces

The fantastic forces was very interesting.  I liked learning how certain forces cancel out the laws of others. For example F=MA.  This also works with pulling a cloth out from under dishes or a glass.  The last thing i really enjoyed was when she put a pencil through wood, with enough force.  Also, the friction of air is enough to slow things down.  

Lightning show

Watching the lighting show i learned that lightning, while can be loud and bright., is actually silent and invisible.  We can see this by rubbing a balloon on someone with long hair.  Also, during a lighting storm, never just lay down on the ground.  Find a grounded place, either a car or a house.  To get rid of your electrical charge, touch someone with a negative charge to balance it out.  

Archimedian Excogitation

This was very interesting to see how one thing can lead to another.  While there was not really any introduction to this, it was still lots of fun to watch it play out and see how all the pool balls need each other in order to keep the next one going.  

Moon and tides connection

   Tides are caused by a gravitational tug-of-war between the sun, moon, and earth. All objects exert gravitational pull on each other. The closer they are, or the larger they are, the greater the pull. All of the planets exert some gravitational pull on the earth. However, the pull of the moon and sun are most noticeable because the moon is so close to us and the sun is so big. It takes the earth 365 days to revolve around the sun. As it revolves around the sun, it spins, or rotates on its axis once every 24 hours. At the same time, the moon revolves around the earth once every 29 days. The gravitational pull of the sun holds the earth in orbit, while the gravitational pull of the earth keeps the moon in orbit.As a result of this gravitational attraction between the earth and the moon, the side of the earth facing the moon is pulled towards it. Solid objects like the ground and buildings are not distorted as much as liquids like the ocean. A bulge of water occurs on the side of the earth facing the moon. As the earth rotates around the sun, centrifugal force causes an equal bulge of water on the opposite side of the earth. Water is pulled away from these two sides of the earth to form these bulges, or high tides. This leaves a depression, or low spot, in the oceans between. These are the areas of low tides.

Chemistry of life

The chemistry of life is necessary for us to survive; different compounds allow us to do different things.  Carbohydrates Proteins, Nucleic acids and fats are all very important to keep our body’s up and running and healthy, every day!  Also, Roughly 96 percent of the mass of the human body is made up of just four elements: oxygen, carbon, hydrogen and nitrogen

The way the wind blows

The earth is unevenly heated because it spins on its axis.  This means that it will heat up in certain parts and not heat up on the part that is deprived from the sun.  The earths rotation affects the movement of water and wind because if the earth did not rotate on its axis, winds would be blowing  from the north toward the south and from the south toward the north. A straight line, as drawn from the equator towards the northern hemisphere the pole or from the North Pole to the equator, as indicated in the example to the left, models this kind of wind direction.

As you probably already know, the earth rotates on its axis from west to east. This rotation causes both the wind and ocean currents to move from east to west. Thus, the wind movement and ocean currents in the northern hemisphere go clockwise and counter clockwise in the southern hemisphere.  Global warming could affects the wind patters because when air is hot it rises, and if too much of the air started to rise, then it would make air to dense in some areas and less dense in other throwing off the wind patterns.  

Chemical Reactions

This week we had been studying chemical reactions.  We first placed steel wool over the Bunsen burner and watched as it slowly deteriorated.  That was a single decomposition.  Next we put a steel nail in a cup of copper chloride and the nail turned a brown/red color.

My best work

I feel my and my groups best work would definitely be A beach by another name.  The reason i feel this way is because we all came together and made intelligent decisions as to where everything should be places.  We had the future of our island planned out far ahead.  The turtles and other animals being healthy, a great view of the beach, nice gold course, and even a convenient Police and Fire station. All in all we planned everything out very well and thought ahead for the future wellness of our island, and that's why i feel this is my best work.

Loggerhead Island

On the side of the island with the sea turtle nesting we needed to consider the precautions of the public being a disturbance, also we added free feeding and food for the animals, to keep offspring healthy and alive. We also located the fire and police station right in the center of civilization in case of emergency's. We made a timer on the street lights so that they do not disturb the nesting. We placed our fishing dock on the lagoon side of the island due to the lack of human disturbance and for marine bio studyin.Our golf course could be flooded by the oceanic side of the island but its close tot he lagoon as well so it may not have any issues. We placed a large netting around the sides so that the golf balls don't enter the ocean. The economic benefits are the public housing is mostly on the lagoon side away from the economic stuff. Humans negatively impact the coastal ecosystems with there rowdiness, pollution, and the electricity distributed around the streets. With healthy vegetation and economy we can severely prevent the issues of storms starting. I wish that made the gold course larger, had more public attractions, and more security of sea turtle nesting.
