If the Sun were the size of a large pizza (40 cm), then Earth would be about as big as
1. A slice of pepperoni (about 5 cm)2. A small piece of diced onion (about 0.5 cm)3. A red pepper flake (about 0.5 mm)4. A medium pizza (about 30 cm)
An Assessment
• Best procedures: read quietly to yourself (so you don’t give any subconscious clues)
• As the instructor, we read it too, for timing, then ask if anyone needs more time
• If not, it’s time to vote simultaneously—use your fingers, right in front of your chest so others don’t see (anonymous)
AnotherArrange the following according to distance from Earth (from least to greatest):
1. Mercury, Saturn, the North Star, the Andromeda Galaxy
2. The North Star, Saturn, Mercury, Andromeda Galaxy
3. Saturn, Mercury, the North Star, the Andromeda Galaxy
4. Mercury, Saturn, the Andromeda Galaxy, the North Star
5. Two of these are the same distance
Which of these analogies works best? 1. Saturn: Solar System as electron: atom2. Earth: Solar System as atomic nucleus: atom3. Solar System: Galaxy as atom: proton4. North Star: Solar System as neutron: atom5. Mercury: Jupiter as electron: proton
