Forces, Earth, and Engineering Solutions
Reflecting on Our Learning Journey Year 4 Science Investigation How Forces Shape Our World
Let's Think Back...
What causes earthquakes to happen? How do earthquakes change Earth's surface? What have we discovered about building design?
Engineering Marvels: Building for Safety
Engineers design earthquake-resistant buildings Special features like cross-bracing and flexible foundations Tuned mass dampers help tall buildings sway safely Smart design saves lives during earthquakes
Before and After Reflection
Complete your reflection worksheet Before this unit, I thought... Now I know that earthquakes... My model showed that... I learned that good designs...
Our Learning Journey Mind Map
Forces That Shape Our Earth
{"left":"Tectonic plates move slowly over millions of years\nEarthquakes happen when plates suddenly slip\nSeismic waves travel through the ground\nThese forces create mountains, valleys, and ocean floors","right":"Vibrations can be measured with seismographs\nDifferent types of waves cause different effects\nEnergy from Earth's core drives these movements\nScientists study patterns to understand Earth better"}
Smart Engineering Solutions
Base isolation systems let buildings 'float' during shaking Flexible materials bend instead of breaking Computer simulations test designs before building Early warning systems give people time to take cover

A Christian Perspective on Science
God has designed an incredible, dynamic Earth that changes and moves. As caretakers, we can use our understanding of science and design to help keep people safe and care for creation wisely.
How Has Your Thinking Changed?
What was the most surprising thing you learned? How can we use this knowledge responsibly? What questions do you still have about earthquakes? How might you use engineering thinking in the future?
