Title:
Temperature and density
Objective:
Determinate in which temperature the density increases
Method:
1) Fill three glasses with 150mlof water.
2) Name each one with letters, A, B, and C.
3) With a thermometer, take the temperature of each glass.
4) Put the three glasses in a refrigerator, and one on thefreezer.
5) After a day, we saw the results of volume and temperature of each glass
Table #1: Conditions of water and temperature
Temperature (°C) | 21 | 8 | 0 |
Volume (ml) |150 | Less than 150 | More than 150 |

Results:
The glass (A) with 21°C, had a volume of 150ml, the glass (B) with 8°C had a volume less than 150ml and finally, the last glass (C),with the temperature of 0°C, had a volume more than 150
Conclusion:
In my opinion, the experiment was successfully because we did all of the steps, very well, we took notes; we drawponds or lakes, which are very interesting themes. Ponds, or lakes, are places where people can swim, and have a great time, but, what happens with a lake in winter? Ponds, in winter,have a slightly thick cap that divides temperatures of the exterior and in the interior, or the water. For example, if the temperature of the outside (exterior) is 289k, the interior, orthe water temperature would be much higher, and the fishes of that pond, would live normally but obviously, the temperature of the water will decrease.
What happens in very coldwinters? Only in the very worst Siberian type winters, ponds freezes into solid, in that case, the fishes and any specie living in a lake, is freeze to death.
