| g) | Do you know what the word astrophysics means? (select all that apply) | 
| i. | The study of the universe using any sort of telescope or detector | 
| ii. | The study of the universe, especially of the positions and motions in space of cosmic bodies |

 |  |  | 
| h) | Do you know what a neutrino is? (select all that apply) | 
| i. | No clue what a neutrino is. | 
| ii. | It’s an elementary particle. The sun produces tons of them. | 
| iii. | It’s a particle of matter, just as an electron or a quark is. | 
| iv. | It’s a particle that helps us explore the universe. | 
| v. | It’s a tiny particle that is very difficult to detect. |

| i) | And what about IceCube, is this a word familiar to you? (select all that apply) | 
| i. | Not beyond frozen water and a rapper. | 
| ii. | It’s a detector in Antarctica. | 
| iii. | It’s some sort of telescope in Wisconsin. | 
| iv. | It’s a special detector that uses neutrinos to explore the extreme universe. | 
| v. | It’s a neutrino and a cosmic-ray detector. |

| k) | What do you think of IceCube’s research?  (select all that apply) | 
| i. | Amazing, I would definitely like to learn more about IceCube science. | 
| ii. | Very interesting. I wish science and engineering lessons at school talked more about real research projects such as IceCube. | 
| iii. | I think it is neat, but I’m personally more interested in other science topics. | 
| iv. | It’s OK, but not that exciting. |
