1).when one tap ball,the energy from his hand moves to the ball,the kinetic energy of the ball change into elastic potential energy,and also,elastic potential energy change into kinetic enregy and gravitational energy.
2).while using solar water heater,solar energy convert to heat energy then creat hit water to give us a bath.
3).While using kettle,the electrical energy pass through the electric heating tube that convert to heat energy,which boil the water.Water is absorbing heat energy.
AltaVista Buffalo Farm was carved out of the New England forest on a hill in the town of Rutland in 1724. The first family who bought it named it AltaViata, that means “high view”.The farm was first a dairy farm until 1965. They purchased heifer calves and made a small herd with 5 to 10 animals.Now the farm is totally a buffalo farm.It sells buffalo meat to the public and also sales buffalos .
1.Buffalo meat contains less fat and cholesterol than beef.It has pure wholesome meat in higher protein and iron.They were once in the millions. There were about 75 million in North America.But slaughtered for their hide, tongue and just for sport, they were reduced to less than 1,000 by 1890. They were nearly extinction. But by some ranchers’ foresight, they started their comeback.And now, the national herd numbers around 350,000.
2. The topography of the farm is generally hilly, encompassing numerous flatter wetlands, broad valleys and floodplains.A low percentage (8.2%) of total impervious surfaces — namely, paved areas such as streets, driveways, and parking lots — for this whole subbasin indicates that concerns of compromised stormwater and other non-point sources of contaminants (for example: pesticides, fertilizers, oils, asphalt, pet wastes, salt, sediment, litter and other debris) is not a pressing concern.
3.Wachusset Mountain,Quinapoxet Resevoir, and Pine Hill Resevoir areas have been identified as important core habitat areas.The Pine Hill Resevoir focus area forms the southern extend of a string of open areas stretching north.It is expetional for the extent of undeveloped hillside directly adjacent to large bodies of water. The area around the resevoirs is known to provide exellent snake habitat. Protection priorities include the Bond Hill and the wetland to the west and unprotected interior parcels such as the area around Worcester Brook north of the Pine Hill Resevoir,and Streeter Pond to the west. There are two major surface water supply systems for the city of Worcester which the Quinapoxet Resevoir, Pine Hill Resevoir and Kendall Resevoirs.Indeed, 36% of the Quinapoxet subbasin’s water is diverted into the city of Worcester’s resevoirs and from there to Blackstone River basin.

This Monday our class went to Nicenicz Farm. The first owner of the farm emigrated from Poland and bought this farm.They first grew apples, peaches and pears.They also harvested bush blueberries and cranberries. Now their granfsons are taking charge of the family farm.There are apples, peaches, pears, pumpkins and vegetables grown in the farm now.1).There are 17 varieties of apples in the farm.They are Brock, Crotland, Fuji,Gala(early), Ginger gold(early), Golden Delicious, Gravenstein(early), Honey Crisp(early), Macintosh, Macoun, Mother,Paula Red(early), Red Delicious, Vista Bell(early), Westfield Seek No Further, Williams Pride and Wolf River.The apples fall from the trees and there are bunch of apples on the ground.There are hundreds of apple trees in the farmstand.People are free to pick apples in fall season.The farm owners use Integrated Pest Management(IPM) for the apples, to minimize the application of chemicals.2).The farm locates at Bolten.Bolten is in the northwest of Boston.It is near the center of Bolten and on the top of Wattaquadock Hill.3).There are lots of types pf pests that effect apples like apple maggot, apple leafminers,apple sawfly and codling moth.The farm uses 25% less pesticide.They use a red croquet ball that hangs on the branch to catch pests.They use pesticides alternately.There are several types of pesticides.Chemical pesticides and biopestcides are two main type of pesticides.

On Oct.20th, our class went to Coopers Hilltop Dairy Farm for field trip.It is a famous farm in Worcester which provides a lot of milk, butter or cream.
It took us about 30 minutes to get there on bus. When we arrived there, I saw it was a very beautiful farm.It had wide nice farmland and advanced machine for making milk and big cowshed. First we visited the milk making machine. It used Pasteurization to hot milk with 143 degrees for half an hour.That was a healthier way. After we took a look at the fridge, we went to the cowshed. It was a huge cowshed that the workers devided the cows with different ages into different groups, because it was more convient to get milk from the adult and old cows that can not get from the young cows. 50-60 cows were milked in the farm and the workers milked 3、4 cows at a time. they use machine to get milk but not their hands.The introducer showed us the farmland and the corns in the farm then. Most of the corns were so tall that were about 9、10 feet and we were told that corns take a big deal from the soil.
We went to the market to buy some products of the farm for our last part of the trip.Then the field trip ended. It was a happy time and I learned a lot about agriculture.
Today,our class went to the Buffone Garden again to winterize it. We have already picked the food in the garden before. First,we looked over the garden.I saw that some tamatoes had turned red under the sunshine.It looked really nice and beautiful.Next,I was assigned to pick any food that left on the ground with Seun and Bryan.I have found plenty of tomatoes that left on the ground and then put them into a basket.Afterwards.Mr. Carroll showed us some worms.He told us that those worms can make nice soil.The rest of the class we were busying pick and put some bad tamatoes into the basket that had worms.I thought though they looked nasty,they were useful and they were good insects.But I am not sure how can those small worms make nice soil?I hope I can get my answer soon.
Three sisters method explained?
“The three sisters” is an ancient method of gardening using an intercropping system which grows corn, beans, and squash crops together in the same growing area that is typically a rounded mound of soil.And it is often called a hill.
The oldest sister is corn,she stands tall among the sisters and she stands tall among the sisters.She is the most important as well.She can make rice,corn,careal nad so on.Those are our human being’s main and they are nutritive.
The next sister is squash.She is the heaviest among the sisters.I think she is very cute,too. She grows over the mound, and protects her sisters from weeds and shades the soil from the sun with her leaves, keeping it cool and moist so her sisters can grow well.
The third sister is bean. She loves the sun very much.She climbs through her sister-squash, and then up corn to bind all together.She help keep the soil fertile by coverting the sun’s energy into nitrogen filled nodules that grow on her roots. As she grows she use the stored nitrogen as food,and of course,she can grow very well.

Air pollution is a problem that is besetting our earth. Sandstorms and the dust and gases from volcanoes pollute the earth’s atmosphere naturally. But the most serious kind of air pollution comes from people. Factories, power stations, and cars exhausts pump harmful gases into the air.Those are causing global warming, acid rain, and destroying the ozone layer.There are no simple solutions to air pollution, but we can reduce air pollution by saving energy and reducing harmful emissions from car exhausts and power stations.
Now that global warming is a really a big problem to our world. one big reason of this is because people are burning soo many trees. Trees can take in CO2 and take out oxygen. Oxygen is good for us to breathe. When people are burning trees, it takes out CO2. CO2 is the gas of the greenhouse. That is making our earth become warmer. Another big reason is the population. As there are soo many people in our earth,we breathe in oxygen and breathe out CO2. The number of CO2 we breathe out 1 year will be countless, and the effect will be ghastly. Lot of glaciers will start to melt and then the sea level is going to rise up, that will badly endanger to our earth.
