grade 9 science scientific method quiz

🧪 Quick Study Guide

• 🤔 The Scientific Method is a systematic way to investigate the world around us.
• ❓ It typically involves these steps: Observation, Question, Hypothesis, Experiment, Analysis, and Conclusion.
• 🔬 Observation: Noticing something and gathering information.
• 📝 Question: Asking what you want to find out.
• 🧪 Hypothesis: Forming an educated guess that can be tested.
• ⚗️ Experiment: Testing your hypothesis through controlled procedures.
• 📈 Analysis: Looking at the data you collected and figuring out what it means.
• 💡 Conclusion: Deciding if your hypothesis was correct based on your data.
• 📊 Control groups are essential for comparison in experiments.
• 📏 Independent variables are manipulated, while dependent variables are measured.
