• Warm air is lighter than cold air, so it rises.
• Low air pressure means stormy weather is coming.
• High air pressure means clear weather is coming.
• A barometer is a tool that is used to measure changes in air pressure.

Lesson 3: Heat and Temperature

• The Sun heats the Earth.
• A thermometer is a tool used to find the temperature of something.

Lesson 4: The Wind

• Wind is air moving in the environment.
• Wind speed is measured with an instrument called an anemometer.
• A weather vane (or wind vane) is a tool that shows the direction the wind is blowing.

Lesson 5: Precipitation

• The Earth revolves or orbits around the Sun one time every year.
• The Earth tilts on an axis.
• The hemisphere closest to the Sun has the warmest weather.

Lesson 9: Geography and Weather

• The weather in an area depends on environmental factors as well as geographical factors.
• The seasons occur because of the Earth's placement in relation to the Sun.
• On the same day, the weather will be different in different geographical locations.

Lesson 10: Habitats and Weather

• Animals have features that help them survive in extreme environments.
• The weather is different in different habitats.
