📐 Understanding Scientific Notation
Format: a × 10ⁿ
- • a = mantissa (1 ≤ |a| < 10)
- • n = exponent (integer)
- • Positive n = large numbers
- • Negative n = small numbers
Examples:
- • 3,000,000 = 3 × 10⁶
- • 0.00045 = 4.5 × 10⁻⁴
- • 1 = 1 × 10⁰
🌟 Scale Examples
Microscopic World
- • Atom: 10⁻¹⁰ m
- • DNA width: 2 × 10⁻⁹ m
- • Bacteria: 10⁻⁶ m
- • Red blood cell: 7 × 10⁻⁶ m
Astronomical Distances
- • Earth radius: 6.4 × 10⁶ m
- • Earth-Moon: 3.8 × 10⁸ m
- • Earth-Sun: 1.5 × 10¹¹ m
- • Nearest star: 4 × 10¹⁶ m
💡 Teaching Tips
- • Use powers of 10 to understand scale differences
- • Practice converting between notation and standard form
- • Compare unfamiliar sizes to known objects
- • Remember: each power of 10 is 10× larger/smaller
- • Use prefixes: kilo (10³), micro (10⁻⁶), nano (10⁻⁹)
⚠️ Common Mistakes
- • Forgetting negative exponents mean division
- • Confusing 10³ (1,000) with 3 × 10 (30)
- • Not normalizing mantissa (should be 1-10)
- • Mixing up unit prefixes and exponents
- • Calculator may need E notation (3E6 = 3 × 10⁶)
