Content Learning Cycle

First Weeks of School

Every PhD Science concept moves through the same five-stage cycle. Understanding what each stage asks of students—and of you—is key to teaching these lessons effectively. Students engage in Wonder, Organize, Reveal, and Distill multiple times within a concept; Know happens once per concept.

1. Wonder: Students observe the anchor or supporting phenomenon, generate questions, connect prior knowledge, and develop an initial explanation. Don’t rush this stage—student questions here drive the entire concept. Facilitate sharing of questions and post them on the Driving Question Board. Your role is to build curiosity, not resolve it.
2. Organize: Students focus on a specific question to investigate. This stage moves from open-ended wondering to a defined question that can be explored. Help students identify what they need to find out and how they might go about it.
3. Reveal: Students investigate—carrying out procedures, analyzing data, gathering evidence. This is the hands-on core of the concept. Confirm safety expectations before students access materials. Encourage observation and recording in Science Logbooks.
4. Distill: Students apply evidence and reasoning to revise their explanation, communicate new knowledge, and compare and synthesize. Discussion is central here. Let students lead—your role shifts to facilitator. Update the Anchor Model and Anchor Chart with student input at the close of each Distill stage.
5. Know: Students connect knowledge across contexts and apply what they’ve learned to a different phenomenon. This consolidation stage is the payoff of the whole cycle. Celebrate the growth in student thinking from Wonder to Know.
