Traditional science lessons follow a recipe: you give instructions, students follow steps, they get a predictable result. Inquiry-based science flips this. Students ask a question, design an investigation, and discover the answer. It's messier, but it's real science.
Step 1: Engage — Hook their curiosity. Show something surprising or puzzling. "What floats and what sinks?" "Why is the sky blue?"
Step 2: Explore — Students investigate freely. No instructions yet. They try things. "Try different objects in water. Notice what happens."
Step 3: Explain — Guide them to understand the science. Ask questions: "What did you notice? Why do you think that happened?" Introduce vocabulary and concepts.
Step 4: Elaborate — Apply the learning. "Now use what you know. Can you predict what will float? Test it."
Step 5: Evaluate — Reflect and assess. "What did you learn? How do you know? What would you investigate next?"
Engage: Show a stone (sinks) and a stick (floats). "How can I make the stone float? Can you?"
Explore: Give students objects and water. They try floating different items, arranging them, testing ideas.
Explain: Guide them: "What do you notice about the objects that float? Are they light? Are they made of specific materials?" Introduce density and buoyancy informally.
Elaborate: Challenge: "Can you float the stone without touching water?" (Tin foil boat, for example.)
Evaluate: "What did you discover? Why do ships made of metal float when a metal spoon sinks?"
You're not the answer-giver; you're the question-asker. "What did you observe? Why do you think that? What could you try next?" This is harder than giving information, but it builds thinking.
Freedom doesn't mean chaos. Clear boundaries: "We're investigating floating and sinking. Stay with water play. No throwing objects." Manage materials beforehand. Have cleanup procedures.
- Plant growth (seeds, light, water)
- Sink and float
- Mixing and separating (salt and sand, oil and water)
- Force and motion (ramps, rolling objects)
- Simple machines (levers, pulleys)
- Human body (pulse, breathing, exercise)
- Weather and water cycle
Students draw, write, or photograph their investigations. "What did you do? What happened? Why?" This records their thinking and creates an evidence trail.
