The 5E Lesson Plan Model: Template and a K–5 Science Example

The 5E lesson plan model organizes a science lesson into five phases, Engage, Explore, Explain, Elaborate and Evaluate, so students investigate a question first and learn the formal concept and vocabulary after they have experience to connect it to. That order is what makes the model different from a traditional lesson, where the teacher explains first and students practice after. The 5E model fits naturally with NGSS-style science, where students make sense of phenomena by doing science. This guide explains each phase, gives you a fill-in template and walks through a complete 2nd grade example on heating and cooling.

Where the 5E model comes from

The 5E instructional model was developed in the late 1980s by a science education team at BSCS. It builds on research showing that students learn more deeply when they explore an idea, compare what they find with their prior thinking and then refine their understanding with the teacher’s help. Today it’s one of the most common lesson formats in elementary science.

The five phases

1. Engage

The goal is curiosity. Present a question, a puzzling event or a short demonstration that connects to students’ lives and makes them want to find out more. Ask what they already think. Don’t explain anything yet; just listen and record their ideas.

Examples: Show a video of a puddle that disappears on a sunny day. Ask, “Where did the water go?”

2. Explore

Students investigate in small groups with materials, observations or data. The teacher asks questions, but doesn’t give answers. Students record what they notice and start forming explanations.

Teacher moves: “What did you notice? What do you think caused that? What could you try next?”

3. Explain

Groups share their findings. The teacher connects their observations to the scientific idea and introduces vocabulary at the moment students need it. Students revise their first ideas from the Engage phase.

Key point: Vocabulary comes after experience. Words like evaporate mean more when students have just watched it happen.

4. Elaborate

Students apply the new idea to a different situation, a new investigation or a design challenge. This is where understanding deepens and transfers.

5. Evaluate

Students show what they understand and reflect on how their thinking changed. Evaluation also happens informally throughout the lesson as the teacher listens and observes.

The 5E template

Above the table, add the standard, the learning goal, the materials list and safety notes. Below it, add differentiation.

Example: Heating and cooling (2nd grade)

Standard: Construct an argument with evidence that some changes caused by heating or cooling can be reversed and some cannot (NGSS 2-PS1-4).

Learning goal: I can use evidence to explain which changes from heating or cooling can be undone and which can’t.

Materials: Ice cubes, chocolate pieces, crayon pieces, small paper cups, a warm water bath (teacher-managed), a picture of cooked and raw eggs, a picture of toast and bread, recording sheets, a class chart.

Safety: The teacher handles all warm water. Students observe from a safe distance.

Day 1: Engage (10 minutes)

Show two pictures: a bowl of melted ice cream and a piece of toast. Ask, “If we put this ice cream back in the freezer, could it become solid again? Could the toast ever become bread again?” Students turn and talk, then share. Record their predictions on a chart titled “Can we undo it?”

Day 1: Explore (30 minutes)

Groups receive an ice cube, a piece of chocolate and a crayon piece in separate cups. The teacher places the cups in a warm water bath. Students observe every few minutes and draw what they see. After the materials melt, the teacher moves the cups to a freezer or ice bath until the next day.

Teacher questions while circulating: “What’s happening to each one? Which melted first? What do you think will happen when they get cold again?”

Day 2: Explore continued (15 minutes)

Groups observe their cooled cups. The ice is solid again, the chocolate and crayon are solid but have new shapes. Then they look at the cooked egg and the toast pictures and discuss whether those changes can go back.

Day 2: Explain (20 minutes)

Groups share their drawings. Build a class chart with two columns: “Can be undone” (melted ice, melted chocolate, melted crayon) and “Can’t be undone” (cooked egg, toast, baked cookies). Introduce the words reversible and irreversible using the students’ own examples. Students revisit their Day 1 predictions and say how their thinking changed: “I used to think ___, but now I think ___ because ___.”

Day 3: Elaborate (25 minutes)

Give each group a set of picture cards: water freezing into ice pops, paper burning, butter melting, a cake baking, wax from a candle cooling, a frying pancake. Groups sort them into the two columns and explain each choice with evidence from the investigation. Then ask: “Why can’t we turn the pancake back into batter?”

Day 3: Evaluate (15 minutes)

Students choose one example and complete a short claim-evidence frame:

• My claim: ___ (can / can’t) be undone.
• My evidence: When we ___, we saw ___.

Collect these to see who can use evidence from the investigation.

Differentiation: Picture-based sorting cards and sentence frames for students who need language support; extension question for early finishers: “Can you think of something that changes when it’s cooled that can’t be undone?”

Why exploration before explanation works

When students explore first, they have something concrete to attach new ideas to. They also notice gaps in their own thinking, which makes the explanation more meaningful. A word like reversible stays abstract until a student has watched melted chocolate become solid again.

Exploration also builds the science and engineering practices: asking questions, planning investigations, analyzing data and arguing from evidence. For more on those practices, see our guide to NGSS science and engineering practices.

Picking a good Engage

The best Engage phases start with a phenomenon: something students can observe that makes them wonder. A good phenomenon is concrete, a little surprising and connected to the unit’s big idea. Our list of NGSS phenomena for elementary has 30 ideas organized by grade.

Common mistakes with the 5E model

• Explaining in the Engage phase. If you tell students the answer first, the Explore phase becomes a demonstration rather than an investigation.
• Exploration without structure. Give a clear question and a way to record. “Play with the materials” isn’t enough.
• Skipping Elaborate. This phase is where students show they can transfer the idea, not just repeat it.
• Evaluation only at the end. Listen and watch in every phase. Students’ talk during Explore often tells you the most.
• Forcing everything into one period. It’s fine to spread a 5E sequence over several days.

Fitting 5E lessons into a unit

A 5E lesson is often one piece of a larger unit. Several 5E sequences can build toward a unit’s big question, each tackling one part of the phenomenon. If you’re planning the bigger picture, our comparison of unit plans vs lesson plans shows how to map a whole unit before writing daily lessons.

Supporting every learner

Students learning English benefit from the hands-on nature of 5E: they can observe and participate before they have all the words. Add picture vocabulary cards and sentence frames for the Explain phase. For students with IEPs or 504 plans, follow documented accommodations, such as reading the materials aloud or giving extra time for the Evaluate task.

Plan 5E lessons faster

Finding a good phenomenon, designing an investigation and writing all five phases takes time. An AI lesson plan tool can draft a 5E lesson from a standard and topic, including questions for each phase, and you adjust materials and timing for your class.
