Begin the lesson by discussing the diversity of organisms on Earth, from ocean depths to mountain peaks. Highlight the importance of classification in understanding this diversity.

Introduce the six main kingdoms: ancient bacteria, bacteria, protists, fungi, plants, and animals. Explain the criteria used for classification such as food acquisition, reproduction, and cellular structure.

Watch the 'Characteristics of Organisms' video to understand the fundamental traits of organisms, supporting the lesson with visual examples.

Engage students in a discussion about the criteria scientists use to classify organisms. Encourage them to think about how these criteria help in understanding organism diversity.

Watch the 'All About Protists' video to explore the unique characteristics of protists and their ecological roles.

Have students explore their schoolyard to observe and classify organisms into the six kingdoms. Use hand lenses and notebooks for documentation.

Use the 'Organisms in the Schoolyard' assessment to guide students in identifying and describing organisms they find.

Assign students to complete the 'Characteristics of Life – Comprehension' worksheet to reinforce their understanding of organism characteristics.

Conduct a class discussion to review the six kingdoms and the criteria for classification. Ask students to share their observations from the schoolyard activity.

Encourage students to reflect on the importance of classification in understanding organism diversity. Discuss the vast number of organisms yet to be discovered.

Administer the 'Review – Classification of Organisms' assessment to evaluate students' understanding of the lesson content.

Encourage students to try the quiz to test their comprehension of the unit.
