Grade 3 science quiz: Does your design work?

📚 Quick Study Guide

• 🔍 What is Design? Design is the process of planning and creating something new. It involves thinking about what the thing will do, how it will look, and how it will work.
• 💡 The Design Process: The design process generally involves identifying a problem, brainstorming solutions, planning, building, testing, and improving.
• 🧱 Building Materials: Different materials have different properties. Some are strong, some are flexible, some are waterproof. Choosing the right material is key to a successful design.
• 🧪 Testing is Important! Testing helps us see if our designs work as planned and where we can make improvements. We can test for strength, stability, and functionality.
• 📝 Simple Machines: Simple machines like levers, pulleys, and inclined planes can make tasks easier. Understanding how they work is important for designing efficient solutions.
