Introduce today’s lesson on change. Explain that we will explore examples of change in our environment, build observation skills, and play a fun matching game. Review the lesson objective: understanding change.

Project this slide. Ask each student to think quietly, then turn to a partner to share. Invite volunteers to name one change they noticed today. List responses on chart paper under “Today’s Changes.”

Distribute the reading passage ([Change Stories Reading](#change-stories-reading)). Read aloud, pausing to point out each change. Ask students to underline change words or phrases in their copies.

Draw two columns on chart paper labeled “What Changed?” and “Why?”. Invite students to share underlined changes from the reading. Record their answers under the appropriate columns, guiding them to explain reasons behind each change.

Hand out [Change Observation Worksheet](#change-observation-worksheet). Students work in pairs to draw or write one change they see at school and explain why it happened. Circulate to ask probing questions.

Divide the class into small groups and distribute [Change Match Game Cards](#change-match-game-cards). Explain the rules: match each scenario card with the correct before/after picture. The first team to finish correctly wins, then review as a class.

Introduce Session 2. Review our goal: to investigate different kinds of change through reading, experiments, discussion, a game, and a quick quiz.

Guide students through the warm-up. Display the slide and instruct them to write two remembered changes and one new prediction. Invite a few volunteers to share.

Distribute the reading. Ask students to read or follow along as you read aloud. Have them underline examples of melting, dissolving, and bubbling.

Lead a discussion of natural, physical, and chemical changes. Chart students’ ideas in three columns. Emphasize key differences.

Explain the two quick experiments. Model how to record observations on the worksheet. Circulate to prompt explanation of why changes happened.

Organize students into teams. Explain that one student will act out a change scenario while others guess the type and cause.

Distribute the quiz. Remind students to work quietly and answer all questions in two minutes. Collect when time is up.
