Science Study Guide- Test Monday

Water Planet Investigation #3 Study Guide                  
Heating Earth’s Materials: Test Monday May 21, 2012

1.       Wind is caused by the uneven heating of Earth by the Sun.

2.       In the demonstration with the air inside the syringe, air was compressed when pressure was applied to the plunger. The amount of air did not change because there was still the same number of molecules; however, the molecules were pressed closer together.

3.       Air is denser at the base of a mountain because there is more of the atmosphere above pushing down on the atmosphere at the bottom, so the atmosphere is more compressed and denser at the bottom.

4.       Wind moves from areas of high pressure to areas of low pressure.

5.       Be able to draw and explain the convection current experiment we did in class with the warm water bag and the cold blue water at the bottom of the vial. The water in the vial next to the warm water warmed up and became less dense. When it got to the top, it cooled, became denser, and began to sink.

6.       Be able to analyze and interpret a dual line graph showing Earth materials in the sun and shade over time (just like the experiment we did outside). Know that dry soil heats more quickly and cools off more quickly than water. Water is a heat sink.
