Question 2 True / False
Your pupils get bigger in the dark to let in more light.
TTrue
FFalse
Answer: True
When it is dark, your pupils open wider (get bigger) to let in as much light as possible so you can see better. In bright light, your pupils get smaller so too much light does not get in. This happens automatically — you do not have to think about it.

Think about your answer, then reveal below.
Model answer: Eyelids close to block things from hitting your eyes, and eyelashes catch dust and small bits before they can get in. Eyebrows also help by keeping sweat from dripping into your eyes.
Your eyes have several built-in protections. Eyelids snap shut when something comes close (you blink without thinking about it). Eyelashes act like tiny filters. Tears wash away dust and germs. Your body takes special care of your eyes because they are so important.
