Learning Objectives

• Define life cycle and explain that living things grow and change in predictable stages.
• Sequence the stages in the life cycles of at least two organisms.
• Compare similarities and differences between different life cycles.
• Use evidence from images or cards to justify thinking in a small group discussion.

Materials Needed

• Life cycle picture cards or slides for butterfly, frog, plant, and human
• Chart paper or recording sheet
• Markers or pencils
• Glue sticks or scissors if using card sort
• Timer
• Exit ticket slips

Support

• Provide fewer cards or only one organism for students who need extra support.
• Use labeled images and a word bank for vocabulary support.
• Assign clear group roles such as sorter, reader, recorder, and reporter.
• Pair students strategically so peers can model language and reasoning.

Challenge

• Ask advanced students to compare life cycles of animals and plants and explain how they are similar and different.
• Have students identify which organisms undergo metamorphosis and justify their thinking using evidence.
• Invite students to create their own life cycle diagram with labels and arrows.

Checks for Understanding

• Listen for correct use of vocabulary during group talk.
• Check whether students can place stages in the correct sequence.
• Use probing questions to confirm understanding of change over time.
• Review exit tickets for evidence of accurate definition and sequencing.

Closure

Revisit the lesson question: 'How do living things change over time?' Ask students to share one new thing they learned about life cycles. Emphasize that all living things go through stages, but different organisms have different patterns of change.
