Weather
Hey, Bill Nye here. Today we are going to go over different weather instruments, what they do, and how they can help you analyze current and predict upcoming weather patterns.
3
Thermometer
We started class with the easy instrument, and we'll start the review with it too. A thermometer measures the air temperature.

5
Thermometers
Using a thermometer and knowing the temperature is really important. For example, where I am it's 65 degrees today. That means when precipitation falls, it falls as rain. Where you are right now, it's below 32 degrees a large part of the day so precipitation would fall as snow or sleet.
6
Barometer
A Barometer meaures air pressure.

8
Barometer
A Barometer has 2 readings, High Pressure, and Low Pressure. When there is a High Pressure, you have a clear, cool, sunny day like I'm having now. Just remember the trick, High Pressure starts with H, and Happy Days (clear, cool, sunny day ) starts with H too.
9
Barometer
Conversely, when the Barometer reads Low, you have a Lousy day. It's rainy, and stormy! Just think Low Pressure starts with L, and Lousy weather ( rainy, and stormy) starts with L too!

11
Rain Gauge
OK, kids, that last one has a lot of information. Let's get another easy one out of the way. The Rain Gauge. It measures how much rain has fallen over a specific amount of time. (Usually per 24 hour period)
12
Rain Gauge
It's important to keep track of how much it has rained so you can look for trends. You can tell when there is a drought (not much rain over a long period of time) or when the ground is over-saturated due to too much rain.
13
Wind Vane/Weather Vane
This instrument is pretty easy. It measures wind direction.
14
15
Anemometer
The cups attached to the anemometer catch the wind as it goes by. The harder the winds blow, the faster the anemometer turns. Obviously the wind is very light here,
16
17
Hygrometer
Kids, the Hygrometer is pretty impoartant. It measures humidity (how much moisture is in the air). Hey, another trick to help remember. Hygrometer and Humidity start with an H.
18
Hygrometer
A hygrometer is an instrument used to measure the amount of water vapor in the air. Some even measure the water vapor in soil, or in confined spaces. Lower than 30% of humidity is dry, and 30% to 60% is considered comfortable. However, the temperature should be between 68F to 79F. Humidity that is higher than 60% will indicate the area is wet.

Weather Maps
Last are Weather Maps. They indicate atmospheric conditions above a large portion of the Earth's surface. Meteorologists use weather maps to forecast the weather.
21
Multiple Choice
Looking at this weather map, the places near the big blue H's (High Pressure System) are most likely experiencing which of the following.
22
Multiple Choice
Looking at this weather map, the places near the big red L's (Low Pressure System) are most likely experiencing which of the following.
23
Multiple Choice
Meteorologists use something that indicates atmospheric conditions above a large portion of the Earth's surface.
24
Multiple Choice
This instrument helps you know which direction the wind is blowing.
25
Multiple Choice
26
Multiple Choice
This is what the troposphere is like at any given time and place.
27
Multiple Choice
This happy instrument measures temperature.
28
Multiple Choice
Cameron used this instrument to see how much it had rained in the past 24 hours.
29
Multiple Choice
Rain, Sleet, Snow and Hail are all forms of water particles that fall from the atmosphere and reach the ground.
30
Multiple Choice
This instrument is used to measure air pressure.
31
Multiple Choice
It could be during a hurricane to see how powerful it is, because meteorologists use this device to measure the wind speed.
32
Multiple Choice
It could be during a hurricane to see how powerful it is, because meteorologists use this device to measure the wind speed.
