Lesson Overview

Students will analyze how air pressure, temperature, humidity, and wind interact to produce weather, and use data to make a basic weather prediction.

Learning Objectives

Explain the relationship between temperature, air pressure, humidity, and wind.
Interpret basic weather data from maps, graphs, and station models.
Predict likely weather conditions using evidence from atmospheric data.
Use academic vocabulary to describe weather patterns and changes.

Materials Needed

Whiteboard or projector
Weather map or sample station model handout
Current weather data chart or graphic
Student notebooks
Pencils/highlighters
Exit ticket slips

Vocabulary

Term	Definition
weather	The condition of the atmosphere at a specific time and place.
temperature	A measure of how hot or cold the air is.
air pressure	The force exerted by the air above Earth’s surface.
humidity	The amount of water vapor in the air.
wind	Air moving from areas of high pressure to low pressure.
forecast	A prediction of future weather based on data and patterns.

Lesson Sequence

Do Now / Warm-Up5 min

Teacher Actions

Display two weather images from different locations. Ask students to write one difference they notice and one question they have about the weather.

Student Actions

Independently observe, write responses, and be ready to share.

Mini-Lesson: Weather Variables12 min

Teacher Actions

Directly teach how temperature, pressure, humidity, and wind are connected. Model one example using a simple weather map or data set.

Student Actions

Take notes and answer guided questions during the model.

Guided Analysis15 min

Teacher Actions

Distribute a weather data set or station model. Think aloud through one example, then ask students to interpret a second example with the class.

Student Actions

Work whole-class to identify patterns, describe evidence, and predict conditions.

Partner Talk Within Whole Class10 min

Teacher Actions

Pose a higher-level question such as: 'How would rising humidity and falling air pressure likely affect tomorrow’s weather?' Facilitate brief share-outs.

Student Actions

Discuss ideas with a nearby partner, then contribute to the class discussion.

Application: Weather Prediction13 min

Teacher Actions

Give students a new weather scenario and ask them to make a prediction using at least three pieces of evidence. Circulate and support reasoning.

Student Actions

Write a short prediction and justify it with data-based evidence.

Exit Ticket5 min

Teacher Actions

Collect a quick assessment prompt asking students to define one vocabulary term and make one weather prediction from provided data.

Student Actions

Individually complete the exit ticket and turn it in.

Support

Provide a vocabulary bank with visuals and sentence frames such as 'I predict ___ because ___.'
Allow students to use color-coding to identify temperature, pressure, and wind patterns.
Pair struggling students with a model response or partially completed organizer.
Re-teach key ideas using simple diagrams before independent prediction.

Challenge

Ask students to explain how changing air pressure can influence cloud formation and precipitation.
Have students compare two weather maps and identify which location is more likely to experience storms and why.
Invite students to use more precise evidence, including multiple variables, in their written prediction.

Checks for Understanding

Cold call students to define and use vocabulary in context.
Observe partner discussions for accurate use of evidence.
Use thumbs up/down after the mini-lesson to check understanding of pressure and wind.
Review student predictions during circulation for scientific reasoning.
Score exit tickets for vocabulary accuracy and quality of evidence-based prediction.

Closure

Review the class prediction question and ask volunteers to share one strong piece of evidence they used. Emphasize that weather forecasting depends on patterns in atmospheric data.

Assessment

Formative assessment will be based on student participation in discussion, accuracy during guided analysis, and the exit ticket prediction using evidence from weather data. Teacher will use exit ticket responses to determine whether students can connect weather variables and interpret basic forecast information.
