Build It: Earthquake-Resistant Models!
Year 4 Science and Technology Designing and Building Strong Structures
Learning Intentions
Build earthquake-resistant structures using design plans Use materials safely and effectively Work together to solve construction problems Test and improve our building designs
What Makes Buildings Earthquake-Resistant?
Think about the features we discussed Share with a partner Be ready to explain your thinking
Safety First!
Use scissors carefully - cut away from your body Ask for help with sharp tools Keep your workspace tidy Share materials fairly with your team Wear safety goggles when needed
Review Your Design Plans
Get your design sketches from Lesson 6 Check your materials list Discuss your plan with your team Identify which features to build first
Our Building Materials
Cardboard for walls and floors Straws and skewers for frames Masking tape and rubber bands for joints String for additional support Plastic cups and small blocks for weight Blu-tack for flexible connections
Building Strong Foundations
{"left":"Wide base spreads weight evenly\nHeavy materials at the bottom\nSecure all joints with tape","right":"Cross-bracing adds stability\nTriangle shapes are very strong\nTest as you build"}
Start Building Your Base
Begin with your foundation Make it wider than your building Add cross-bracing for strength Test stability before building up Record any changes to your plan
The Power of Triangles
Triangles are the strongest shape They don't change shape under pressure Use straws or skewers to make triangular supports Add triangles wherever you need strength
Problem-Solving Check-In
What challenges are you facing? How are you solving problems? Which materials work best for your design? Share your solutions with nearby teams
Continue Building Up
Add your walls and upper structure Keep checking your design plan Make sure joints are secure Add more triangular supports if needed Keep your building balanced
Making Adjustments
It's okay to change your original design Explain why you made changes Test your building as you go Record your improvements in your construction log
