What is Weather?
Air in motion.
What is wind?
From this activity you observed, how air pressure, mass of the atmosphere and composition of gases change as the altitude increases.
What is “Elevator to Space”?
The combination of nitrogen, oxygen, some argon, carbon dioxide , ozone, water vapor and other gases.
What are the gases that make up Earth's atmosphere?
This shows air pressure on a weather map.
What is an isobar?
An instrument that measures thermal energy as temperature.
What is a thermometer?
A storm caused by strong wind and sand or dust.
What is a sandstorm?
From this activity, you observed the different pressures in two different areas, the wind speed and direction.
What is an “Air Pressure Map”?
Plants and algae convert light energy into chemical energy by making sugar (food) out of carbon dioxide and water.
What is photosynthesis?
The pull or force between Earth and the matter in an object or substance.
What is weight?
The tool used to measure the direction from which the wind is blowing.
What is a wind vane?
Lumps of ice that are normally fairly round and no larger that a centimeter in diameter.
What is a hailstone?
For this experiment, you designed a pressure indicator that helped observe the behavior of the particles of air.
What is “Pressure in a Jar”?
Cattle produce this gas in their digestive processes.
What is methane?
A space containing almost no matter, not even air.
What is a vacuum?
One of the best ways to detect the weather. HINT: Always keep an eye at the sky and you'll usually be on top of weather conditions.
What are your eyes?
The layer of the atmosphere closest to Earth's surface and where weather occurs.
What is the troposphere?
From this activity you observed, air particles move into a smaller volume, the air particles size don’t change, the particles speed up and collide more often.
What is “Gas in a Syringe”?
The second most abundant gas.
What is oxygen?
If air is under high pressure in one area and has less space to move around in, and it can escape, air particles will flow from the area of high pressure to low pressure, until the pressure, or air density, is equal.
What is equilibrium?
The weather instrument used to determine the speed of the wind.
What is an anemometer?
Low atmospheric pressure, warm tropical ocean, high wind speeds, the presence of a tropical storm.
What weather factors might help you forecast a hurricane?
From this activity you observed, how air pressure, temperature and dew point change as the altitude increases.
What is the “Weather Balloon Simulator”?
This gas plays an important role in the lives of plants and algae.
What is carbon dioxide?
The constant motion of air particles causes this:
What is air pressure?
A weather tool that measures humidity.
What is a hydrometer?
