This quiz is all about shiny things. Will there be a glimmer in your eye as you get 5/5?

#1. Which of the following is the most important for making clear reflections?

A curved black piece of plastic can make great reflections, as long as it’s smooth.

#2. If you see a star in the night sky that doesn’t twinkle, what is it likely to be?

Twinkling happens when the narrow beam of starlight is bent slightly by the air above us. Planets are much closer than stars, so the beams of light coming from planets are much wider, and it takes a lot more bending to make them twinkle.

#3. Where does the Sun’s energy come from?

The Sun’s energy comes from fusing hydrogen atoms together to make helium atoms.

#4. What is Noctiluca scintillans?

Noctiluca scintillans is a marine organism that glows blue when disturbed. In large quantities, it can make an entire beach glow!

#5. What’s the chemical symbol for silver?

Silver is called argentum in Latin, which is why it has the symbol Ag. It’s also what the country Argentina is named after!
