🔬 Part 1: Planning Your Investigation

1. What do you think makes a building earthquake-proof? Circle your best prediction:

Very tall and thin structures

Wide base with strong connections

Heavy materials at the top

2. Write your hypothesis (what you think will happen and why):

I think that _________________________________ structures will survive earthquakes best because _________________________________.

3. What materials will you use for your investigation?

4. To make this a fair test, what should stay the same for each structure you build?

📊 Part 2: Recording Your Results

5. Draw and label your three different structure designs:

6. Complete the results table:

7. Create a simple bar graph showing how many structures survived the earthquake test:

8. Was your hypothesis correct? Explain your answer:

9. Which design features helped structures survive the earthquake? Circle all that apply:

Wide, stable base

Strong connections (joints)

Shorter height

Triangular shapes for support

10. If you could improve your investigation, what would you change to make it more fair?

11. How do real engineers use this knowledge to build earthquake-safe buildings?
