Lesson Overview

Students analyze short weather data sets to identify patterns, compare variables, and make a simple evidence-based forecast. Designed for a substitute teacher, this lesson is fast-paced, low-prep, and discussion-based.

Learning Objectives

Interpret basic weather data from graphs or tables.
Identify relationships among temperature, humidity, wind, and precipitation.
Use evidence to make a reasonable short-term weather prediction.
Explain scientific reasoning using accurate weather vocabulary.

Materials Needed

Board or projector
Printed or projected weather data table or graph
Pencils or paper
Optional: colored markers/highlighters

Vocabulary

Term	Definition
humidity	The amount of water vapor in the air.
air pressure	The force of air pushing on the atmosphere; it often changes before weather changes.
precipitation	Water that falls from clouds as rain, snow, sleet, or hail.
forecast	A prediction about future weather based on data and patterns.
trend	A general pattern or direction in data over time.

Lesson Sequence

Do Now: Observe the Data2 min

Teacher Actions

Display a simple weather table or graph showing temperature, humidity, wind speed, and precipitation chance over 3 days. Ask students to silently notice patterns.

Student Actions

Individually examine the data and write one observation.

Mini Discussion: What Changed?3 min

Teacher Actions

Ask: What variables increased or decreased? Which day seems most likely to have rain? Guide students to support answers with evidence from the data.

Student Actions

Share observations and justify answers using data from the chart.

Small Group Task: Make a Forecast5 min

Teacher Actions

Direct students to work in pairs or groups of three. They must make a one-sentence forecast for the next day and include at least two data-based reasons.

Student Actions

Collaborate to write a forecast and evidence statement.

Whole-Class Share3 min

Teacher Actions

Call on a few groups to share. Press for scientific language and clear evidence. Clarify misconceptions about weather vs. climate and about cause/effect.

Student Actions

Present forecasts and compare reasoning with other groups.

Exit Closure2 min

Teacher Actions

Ask students to complete a quick oral or written response: 'One pattern I noticed was... The best evidence for tomorrow’s weather is...'

Student Actions

Submit a brief response or share aloud before leaving.

Support

Provide sentence frames such as: 'I predict __ because __ and __.'
Allow students to point to the data instead of writing a full explanation.
Pair students strategically so one can read the chart and one can explain the pattern.
Use a simplified version of the graph with fewer data points if needed.

Challenge

Ask students to explain how a change in air pressure could affect the forecast.
Have students compare two variables and describe which one is a stronger indicator of precipitation.
Require students to identify a possible source of error or uncertainty in the data.
Ask students to propose one additional piece of data that would improve the forecast.

Checks for Understanding

Cold call: Which data point best supports a rain forecast?
Thumbs up/down: Is weather the same as climate?
Listen for evidence statements that use two or more weather variables.
Quick prompt: What trend do you see across the three days?

Closure

Reinforce that meteorologists use patterns in multiple variables to make forecasts. Remind students that strong predictions are based on evidence, not guesses.
