1. Explain the principle on how a wind vane works.
A wind vane is an instrument that is used to measure the winds direction. To do this, the wind vane spins and then points to which direction the wind is coming from. One end of the wind vane is shaped like an arrow and that is the side that points to the direction of the wind. The other side looks wider and that’s the side that catches the wind to move. The wind vane points to the direction the wind is coming from.

2. Determine the wind direction if the arrow points southeast?
If the arrow on the wind vane is pointing southeast then the wind direction is southeast because the arrow points to which direction the wind is coming from.

This can help know when storms or severe weather are coming in as well.

4. Describe the causes of wind.
Wind is caused by airflow from high pressure to low pressure, which would be the differences in the atmospheric pressure. When a difference in this pressure occurs winds move from a higher to a lower pressure, resulting in winds. These winds can also have a variation of speeds. Although, because the Earth rotates the flow does not flow directly from high to low, but instead from the right so that wind flows mostly around the high and low pressure areas.

5. Provide the rule used for determining the direction wind will blow.
The rule used to determine the direction wind will blow is done by the direction the wind originates from. You can use your index finger to tell the direction of the wind. Wet the finger then point it upwards. The side of your finger that feels cool is the direction the wind is blowing. The cool feeling is caused by increased evaporation of moisture on the

Make predictions on what would happen if the barometer was put in direct sunlight?
I predict that if the barometer was put in direct sunlight that the temperature would have an effect on the pressure of the barometer. I think that the warm air will take up the same amount of space as cold air making more pressure.

3. Contrast the movement of the balloon with high low pressure?
When the air pressure is high, the air outside of the can will be heavier than the air inside. This will cause the balloon to be sucked down into the can more pointing the pin higher up on the graph. When the air pressure is low the air will press against the balloon and it will stretch causing the pin to point lower on the graph.

4. Predict the air pressure changes you experience on an elevator?
When on an elevator the pressure changes are due to the acceleration of the elevator and the gravity. When moving up in the elevator the less dense the air becomes. And the opposite happens in the opposite direction moving down.
5. Formulate a hypothesis on the condition of your unprotected body out in space? Deep under the
