There are many ways that I see science in the real world. I can see it all the time. One way I see science is when I watch TV or use a computer. What happens is electricity from the power source is used to make light and heat for the pixels on the TV or computer screen so you can see what’s on the screen. A cable box tells the picture what to display in a TV and I’m not sure what tells the pixels what color they should be in a computer.

Another way I see science is when I work on my Airsoft guns. It starts with the battery which runs a motor. The motor turns gears inside the gearbox. The gears pull back a cylinder and the cylinder is connected to a spring, when the teeth on the gear release the cylinder the spring pushes the cylinder forward and pushes air through an air nozzle and forces a bb out the barrel of the Airsoft gun. So the energy starts out as electrical then goes to kinetic when the gears and cylinder are moving, it stays at kinetic energy until the bb hits an object. When the bb leaves the barrel it is affected by wind and fluid resistance. Once the bb hits an object the energy from the bb is transferred to the object usually by making a noise and leaving a mark. When the bb hits the ground it losses all potential and kinetic energy and doesn’t move.

One more way that I see science in the real world is when I eat. When I eat the food it is crushed when I chew it. Then the food particles are swallowed. The nutrients in the food are slowly absorbed in my intestines. Then I use the nutrients from the food for energy. Energy can be used to do millions of different things. The original energy from the food can be traced back to the sun. The energy goes from potential to kinetic and back to potential.

One more way I see science is when swim. The energy from food I eat which is chemical energy is transformed into energy that I use to swim through water. When I swim two forces the slow me down are fluid friction and gravity. But my buoyancy can counter the effect of gravity. The fluid friction really slows me down though so it takes a lot of energy to swim.

Another way I see science is when I listen to music. The power outlet powers my mp3 player’s battery. The mp3 player uses the power for the earbuds. The earbubs create vibrations that are sent into my ears. My brain turns these vibrations into music for me. 2/1/10
One more way that I see science in the real world is when I cook. When I mix all of the ingredients together in a bowl and then put into a cake pan it is a physical change. To mix and pure the ingredients I need to use energy and I get that energy from eating. Then I move the cake pan into an oven. Energy from a power outlet is turned into heat in the oven. The oven bakes the cake making the ingredients in the cake pan rise and turn into to a different substance. This is a chemical change. When it is done people would eat the cake which causes a chemical change because the cake becomes energy for us.

Another way I see science in the real world is when I snowboard. I get onto a ski-lift that uses electric energy and takes me to the top of the mountain. When I am at the top of the mountain I have mostly potential energy. When I go down the mountain my potential energy turns into kinetic energy. Forces like sliding friction and fluid friction act on me. Sliding friction is caused when my board is on the snow and the surfaces rub together and create friction. Fluid friction is caused by the fluids in the air. When I reach the bottom of the mountain my kinetic energy is at its max. Then I get on the lift for another run. 2/15/10
One more way I see science in the real world is when I drive. The gasoline from the gas station goes into the car engine, from there the gas is pumped into a cylinder and the gas is ignited. This causes the gas to expand making the cylinder move allowing the engine to have the exhaust from the gas exit and more gas allowed into the cylinder. This process causes an axle to turn making the wheels turn propelling the car forward.

Another way that I see science in the real world is when I do target practice at a gun range. When a shot gun shell is loaded into a gun and the gun is pumped it is loaded into a chamber. When the trigger is pulled a firing pin hits an igniting substance that causes the gun powder to ignite and expand. This forces the shot out of the shotgun shell and it is propelled very fast outward. When the shot is in the air, fluid friction from particles in the air and gravity are working against it to slow it down. When or if the shot hits a clay pidgin the force of the shot causes the clay pidgin to shatter or parts of it will come off. To load another round in you have to use the pump for pump acting shotguns.
