Welcome children and introduce the lesson. Explain that today we will learn about our world—its land and water—and how we can care for it. Show excitement and ask if anyone has heard of oceans or continents.

Gather students on the carpet in a circle. Play the Earth Song video. Encourage children to sing, clap, and move. Point out and emphasize the words “land” and “water” when they appear in the song.

Show each page of the storybook slowly. After each page, ask: “What do you see here? Land or water?” Encourage children to point and name features.

Hand out worksheets and sorting trays. Model sorting one picture card. Let each child pick a card, name it, and place it under land or water. Circulate to prompt and praise responses.

Display blue and brown paper, glue, and scissors. Demonstrate tearing or cutting shapes for oceans and continents. Encourage children to name each piece as they glue it onto their collage.

Ask children: “How can we help keep our Earth clean?” Highlight suggestions like picking up trash or saving water. Guide children to return materials and tidy their workspace.
