3. Drought - A long period of little to no rain.
4. Storm Surge - a dome of water that sweeps across the coast where a hurricane lands.
5. Isobar - Lines joining places on the map that have the same air pressure.
6. Isotherm - Lines joining places on the map that have the same temperature.
7. Meteorologist - A person who studies weather.
Week One (September 3rd - 6th)
- Observation - Paying close attention to your surroundings. What do you see, hear, smell, touch, or taste.
- Hypothesis - an educated guess and it must be testable.
- Variable - Any factor that can change in an experiment.
- Experiment - A procedure to test the hypothesis.
- Conclusion - The answer to the hypothesis; including what you learned from the experiment.

- Air Mass - a huge body of air that has a similar temperature, humidity, and air pressure.
- Front - The boundary where two air masses meet.
- Cold Front - A fast moving cold air mass overtakes a warm air mass. This brings sudden changes in weather and once it passes you often have clear skies and lower temperatures.
- Warm Front - A warm air mass overtakes a slow moving cold air mass. After a warm front has moved through the weather is generally warm and humid.
- Stationary Front - Cold and warm air masses meet, but neither can move the other. This usually brings many days of clouds and precipitation.
- Occluded Front - A warm air mass is caught between two colder air masses. The weather may turn cloudy and rain or snow may fall.
