Lesson 12 of 12

🏆 Science Fair Project

🎯 Grades 6–8⏱ ~30 min💚 Intermediate

What You'll Demonstrate

  • Choose an original testable question
  • Design a controlled experiment with identified variables
  • Collect and graph real data, then draw conclusions

Choosing Your Question

A good science fair question is testable, measurable, and original. Avoid questions answered by opinion or that can't be controlled.

Good: "Does the color of light affect how fast bean seeds germinate?"
Bad: "Is science fun?" (not testable/measurable)

Project Checklist

  1. ❓ Write your question in "How does X affect Y?" format
  2. 💡 State your hypothesis: "If X, then Y because..."
  3. ⚖ Identify independent, dependent, and controlled variables
  4. 📊 Run the experiment at least 3 times (trials) for reliability
  5. 📈 Record data in a table; display it in a graph
  6. 🥊 Write a conclusion: was your hypothesis supported? Why or why not?
  7. 📋 Prepare a display board: Question, Hypothesis, Procedure, Data, Conclusion
💡
Oklahoma Science Fair Topics

Great local topics: effects of Oklahoma soil types on plant growth, tornado shelter materials, water quality testing from local sources, effects of heat island effect in Tulsa/OKC compared to rural areas.

Quick Check

Why should you run an experiment multiple times (multiple trials)?

ATo change the hypothesis
BTo increase reliability and reduce the effect of random errors
CBecause the first result is always wrong
