examples of research questions grade 7

📚 Quick Study Guide

• 🧪 A research question is a question that a study or research project aims to answer. It's like the main goal of your investigation!
• 🤔 Good research questions are clear, focused, and specific. They should be answerable through investigation.
• 🔬 In chemistry, research questions often involve investigating the properties, composition, reactions, and uses of matter.
• 💡 When forming your question, think about what you can actually test in a 7th-grade science lab. Keep it safe and manageable!
• 📝 Examples of keywords to include: "How does...", "What is the effect of...", "What happens when..."
• ⚖️ It's important to identify the independent variable (what you change) and the dependent variable (what you measure).
• 📊 Always think about how you'll collect and analyze data to answer your question.
