🔺 Pyramids & the Science Behind Their Shape

---

🏗️ What is a pyramid?

A pyramid is a structure with:

• A wide base
• Sloping sides
• A pointed top

The most famous pyramids are in Egypt, built over 4,500 years ago.

---

🧠 Why did ancient people choose the pyramid shape?

1️⃣ Super strong shape 💪

• The wide base spreads weight evenly
• Sloping sides push weight downward, not outward
• This makes pyramids very stable

👉 That’s why pyramids can stand for thousands of years!

---

2️⃣ Earthquake-resistant 🌍

• During shaking, force moves down the slopes
• Less chance of collapse compared to tall straight walls

---

3️⃣ Easy to build taller 🧱

• As the pyramid goes up, it gets lighter
• Smaller stones are needed near the top

---

📐 Science of angles

• Pyramid sides are built at a careful angle
• Not too steep → won’t fall
• Not too flat → won’t slide

Ancient builders used math and geometry 📏

☀️ Science & astronomy

• The Great Pyramid is aligned with:
  • North, South, East, West
• This shows knowledge of:
  • Stars ⭐
  • Sun ☀️
  • Earth’s directions 🧭

---

🌡️ Temperature control

• Inside pyramids:
  • Cool during day
  • Warm at night
• Thick stone walls act as natural insulation

---

🪨 Materials science

• Made from limestone and granite
• Heavy stones placed with precision
• Used ramps, levers, and teamwork

❌ Pyramid myths (clarified)

• ❌ No magical power beams
• ❌ No aliens
• ✔️ Built by skilled human engineers

---

🧠 Easy way to remember

Pyramids are strong because their shape spreads weight downward
