Weather | Substitute Teacher
Students explore how physics explains everyday weather patterns, including temperature, pressure, wind, humidity, clouds, and precipitation. The lesson is designed to be simple, low-prep, and easy for a substitute to run with discussion, observation, and a short activity.
| Term | Definition |
|---|---|
| Temperature | A measure of how much kinetic energy the particles in air have. |
| Air pressure | The force exerted by air molecules pushing on a surface. |
| Humidity | The amount of water vapor in the air. |
| Condensation | The change of water vapor into liquid droplets. |
| Wind | Air moving from areas of higher pressure to lower pressure. |
| Precipitation | Water falling from clouds as rain, snow, sleet, or hail. |
Take attendance, briefly introduce the topic, and explain that today’s lesson is a simple look at the physics behind weather. Ask students to name one weather condition they noticed today.
Respond to the warm-up question and share a few observations.
Using the board, explain four core ideas: warm air rises, cool air sinks, differences in air pressure create wind, and water vapor condenses into clouds when air cools. Keep explanations short and concrete with examples from daily weather.
Listen, take notes if desired, and answer quick verbal questions.
Show a weather image, forecast map, or ask students to think of a recent weather event. Prompt them to identify where temperature, pressure, humidity, clouds, or wind might be involved. Correct misconceptions gently and keep the discussion moving.
Discuss in pairs or as a whole class and connect the image or example to vocabulary terms.
Ask students to write a short paragraph explaining one weather condition, such as rain, wind, fog, or thunderstorms, using at least three vocabulary words. If needed, write sentence starters on the board: 'Wind happens when...' 'Clouds form when...' 'Rain falls because...'
Complete the quick write individually and use the vocabulary terms in context.
Invite a few volunteers to read their explanations. Summarize the strongest ideas on the board and reinforce the main physics concepts.
Share responses and listen to classmates.
End with a short review of the day’s key idea: weather is driven by energy transfer, air movement, and water changing state. Remind students what they learned and transition to the next class.
Answer the closing question and prepare to leave.
Review the main takeaway: weather is not random; it follows basic physics involving heat, pressure, motion, and water vapor. Thank students for their work and remind them of the key vocabulary.
