they say that a body of water makes a place colder. is it true? can ya give me a site? im doing a science project.

A body of water makes the temperature change more slowly. If it is a large cold body of water, it will make the entire area colder due to the difficulty of raising its temperature. A small pond, once it has been warmed up by the sun, can keep the area around it a little warmer in the evening when the sun goes down, though.

The thermal conductivity of water is poorer as compared to the land. Hence, it warms up at a slower rate and also cools down at a slower rate.
Hence, when you have a water body nearby, during hot seasons, since water is still cooler than land (it takes longer to warm it up in the sunlight), it helps to keep the air also cooler. Similarly, during winter times, since the water is still warm from the summer season, it helps to keep the air warmer.
The classic effect is visible at seashores wherein the extremely large water body (sea, ocean) has such a lag in cooling and warming that the temperatures almost remain constant (or fluctuate in a narrow band).

If a place is sorrounded by a water body or if it is a coastal place, the diference between the max.temperature and min. temperature in a day is kept minimum by the water.Because the land is heated quiekly in day time and gives out the heat quiekly after sunset ,whereas water absorbs the heat slowly in the daytime and releases the heat slowly in the night, warming the sorrounding areas during night .So water controls the temperature variations in the nearby places.

I think a large body of water such as one of the Great Lakes tends to moderate the temperature if you are down wind. For example, look at Wisconsin and Michigan with Lake Michigan in the middle. Lake Michigan acts like a heat sink in the summer and a heat source in the winter. In the winter, cold air moves out of Wisconsen over Lake Micigan when it is warmed by the lake water. By the time it gets to Michigan the air mass is warmer (and wetter). The opposite happens in the Summer. Hot air comes out of Wisconsen and is cooled as it goes across the lake. Sorry I don't have a reference.
