Weather | Substitute Teacher
A substitute-friendly, introductory lesson on the physics behind weather, focusing on air pressure, temperature, humidity, wind, and clouds. Students will explore how energy from the Sun drives atmospheric motion and how basic physical principles help explain common weather patterns.
| Term | Definition |
|---|---|
| Temperature | A measure of the average kinetic energy of particles in air. |
| Air Pressure | The force exerted by air molecules on a surface. |
| Humidity | The amount of water vapor in the air. |
| Wind | Air moving from higher pressure to lower pressure. |
| Condensation | The process where water vapor changes into liquid droplets. |
| Cloud Formation | The visible result of water vapor condensing into tiny droplets or ice crystals. |
| Front | The boundary between two air masses with different properties. |
Show 2–3 weather images or a local forecast. Ask: What physical conditions might be causing these weather patterns?
Observe, think-pair-share, and list initial ideas about temperature, clouds, rain, wind, or pressure.
Briefly explain how uneven heating from the Sun creates temperature differences, which lead to pressure differences and moving air. Define humidity, condensation, and cloud formation using simple examples.
Take notes, answer quick questions, and identify where each concept appears in daily weather.
Give short scenarios such as warm, humid air rising; a low-pressure system forming; or cool air meeting warm air. Guide students to predict what weather may occur and why.
Work individually or in pairs to match physics ideas to likely weather outcomes and justify answers.
Provide a simple weather map or forecast table. Ask groups to identify pressure patterns, likely wind direction, and possible cloud or precipitation changes.
Discuss observations and prepare a brief explanation of the forecast using vocabulary terms.
Ask students to write a short response to one prompt: 'Explain how differences in air pressure create wind' or 'Explain how cooling air leads to clouds.' Collect responses before dismissal.
Write an individual response using at least two vocabulary terms and submit it as a quick assessment.
Summarize the lesson by connecting the Sun’s uneven heating to temperature differences, pressure changes, wind, and cloud formation. Emphasize that weather is a physical system driven by energy transfer and fluid motion in the atmosphere.
Students complete a short written exit response explaining one weather process using at least two vocabulary terms. The response is collected and used as the lesson assessment.
