Give the five phases different jobs
Engage, Explore, Explain, Elaborate, and Evaluate form the five-phase planning scaffold. Explore gives students something to reason from; Explain develops that reasoning; Elaborate asks them to use it in a changed situation. The South Carolina planning guide separates teacher and student actions and allows the sequence to span class meetings. Its scaffold does not replace district requirements.
Use the original illustrative light-and-shadow plan below as a starting point. The investigation asks: What changes in the shadow when we move an object while keeping the light and screen fixed? Observation fields stay empty until students investigate.
Prepare a teacher-approved flashlight, an opaque object, a screen, position markers, and a recording sheet. Use the school's safety directions, including where the light may be pointed. Do not substitute an AI-generated safety approval for those directions.
A filled sequence across two 40-minute meetings
| Phase | Planned time | Teacher work | Student work | Evidence carried forward |
|---|---|---|---|---|
| Engage | Meeting 1, 0-8 | Show the arrangement and ask for a prediction without supplying the result. | Sketch what they predict will change and explain why. | Initial prediction and question. |
| Explore | Meeting 1, 8-30 | Keep light and screen positions fixed; support safe testing and ask what students are comparing. | Move the object between marked positions, sketch shadows, and record observations. | Position-labeled observations, with no invented measurements. |
| Explain | Meeting 1, 30-40; Meeting 2, 0-10 | Ask students to use their records; clarify relevant terms and the explanatory model. | Compare observations and explain a pattern using their evidence. | An explanation that names the conditions tested. |
| Elaborate | Meeting 2, 10-30 | Introduce a changed arrangement: keep the object fixed and move the screen. | Use the earlier explanation to predict, test, and discuss whether it fits this new arrangement. | Prediction and comparison in a different context. |
| Evaluate | Meeting 2, 30-40 | Present an untested arrangement diagram and ask for an individual prediction with reasoning. | Draw a prediction, cite relevant prior observations, and identify something still uncertain. | Individual evidence of reasoning and limits. |
Meeting 1 totals 40 minutes; Meeting 2 totals 40 minutes. Explain receives 20 minutes across the two meetings. These allocations are planning choices, not required phase lengths.
Keep the evidence traceable
The recording sheet needs labels for the fixed conditions, the changed condition, the prediction, and the actual observation. An unlabeled shadow sketch cannot tell a reviewer which arrangement produced it. Leave measurements blank if students did not measure; do not turn a sketch into a precise length.
During Explain, ask, “Which observation supports that statement?” A response such as “The shadow changed” needs a position reference and a description of the change. The teacher can introduce terminology after students have evidence to discuss, then ask them to improve the explanation.
Elaborate must do more than repeat the first test with another object. Here it changes which part of the arrangement moves. Students have to decide how to use the earlier evidence and whether the new test supports their prediction.
Make Evaluate reveal the reasoning
For the individual check, supply a fresh diagram with clearly marked positions. Ask students to predict the shadow, identify which earlier observation informs their prediction, and state one limit of what they can infer. Prepare the actual diagram before teaching; do not assess a student against a diagram the plan never supplied.
Use a simple evidence note: “Prediction: [student response]; supporting observation: [reference]; follow-up teaching: [decision].” Leave it unfilled in the planning template. A complete five-phase schedule does not establish that learning occurred.
Copy a prompt for your investigation
Draft a 5E teaching sequence in US English.
Grade/course: [input]

Prior observations or learning: [inputs or blank]
Required standards and planning format: [paste exact requirements]
Plan Engage, Explore, Explain, Elaborate, and Evaluate. Separate teacher and student actions for every phase and name the evidence passed into the next phase. Explore must give students a task to investigate before the explanatory model is supplied. Elaborate must specify a changed situation that requires applying the idea, not simply repeating the first activity. Evaluate must collect individual evidence of reasoning. Keep prediction and actual-observation fields distinct and leave actual results empty.
Do not invent measurements, experimental outcomes, standards, safety approval, or student understanding. Use [NEEDED: input] visibly. Keep the sequence within each meeting's supplied minutes and show any scheduling conflict. Identify the fixed and changed conditions and missing materials. Preserve the district's required planning format.
Rehearse the handoff between phases
Walk a co-teacher through what students will bring from Explore into Explain and what changes in Elaborate. If your team uses an HTML phase map, NOS can save and render it while you inspect those transitions. Keep the district plan and approved safety directions authoritative. Before teaching, put the actual investigation sheet and final diagram beside the sequence so each phase has the evidence it needs.
