What Do These Tools Do
. Measures Temperature.
. Measured in degrees Fahrenheit or Celsius
.Always points north
.Used to tell direction
.Measures wind speed
.Measures relative humidity
.Measures air pressure
.Sailed in millibars
How Do They Work????
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.
A compass points to the earths magnetic field which appears at the THE NORTH POLE
Anemometers measure wind speed by how fast the bowl shaped cups make a full 360 spin. The faster they spin the faster the wind.
Uses mercury to measure the density in the water.
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
The rain gauge is just a jar with a ruler in it.
How To Use Them!!
Just place it out side and in a few minutes you will have your Temperature
Just face were the red needle is pointing
Hold firmly in hand wait for wind, read number on screen
Just place it outside and wait soon you will see the relative humidity
Just place it outside wait for a few minutes and you will soon have you air pressure reading
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.
Here are some pitchers of weather tools
. Tin Foil
. Wax Paper
. Saran Wrap
. 4 2L Bottle
. 4 Thermometer
. 1 Lamp
. Exacto Knife
First we will cut the 2 litter bottles and put 1 sheet of tin foil wax paper or saran wrap in the bottle except for 1 which will be our control (normal) bottle It will look something like this
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
