What Do These Tools Do
Thermometer
. Measures Temperature.
. Measured in degrees Fahrenheit or Celsius
Compass
.Always points north
.Used to tell direction
Anemometer:
.Measures wind speed
Hygrometer
.Measures relative humidity
Barometer
.Measures air pressure
.Sailed in millibars
Rain gauge
.Measures rainfall

How Do They Work????
Thermometer
You know the red thing at the bottom of the thermometer that looks like blood. well it's actually a type of alcohol and it's volume increases as it get's warmer and decreases as it gets cooler.

Compass
A compass points to the earths magnetic field which appears at the THE NORTH POLE

Anemometer
Anemometers measure wind speed by how fast the bowl shaped cups make a full 360 spin. The faster they spin the faster the wind.

Hygrometer
Uses mercury to measure the density in the water.

Barometer
It Absorbs the mercury in the air, mercury is like a mineral in the air so the more mercury around the air means more air pressure

Rain gauge
The rain gauge is just a jar with a ruler in it.

How To Use Them!!
Thermometer
Just place it out side and in a few minutes you will have your Temperature

Compass
Just face were the red needle is pointing

Anemometer
Hold firmly in hand wait for wind, read number on screen

Hygrometer
Just place it outside and wait soon you will see the relative humidity

Barometer
Just place it outside wait for a few minutes and you will soon have you air pressure reading

Rain gauge
Just place a ruler in a jar place jar outside WHEN IT'S RAININGwait till rain stops and see how many inches of rain happened.

Then after that is done we will place saran wrap on the top of the bottle and place a thermometer in the bottle. Then we turn on the lamp and record every 2 minuts for 40 minuts
