the answers are in black.
1) When a paper plane flies, what is drag?
2) Are minerals made of rocks, or are rocks made of minerals?
3) In your body, the cells that divide the fastest are related to what? Is it a) hair, b) eyesight or c) blood?
4) The 2014 Nobel Prize in Physics was awarded for creating what colour of light emitting diodes (LEDs)?
5) Which planet has a moon called Ganymede?
1) Drag is a force that acts in the opposite direction to the moving paper plane. It is caused by air hitting the plane and slowing it down.
2) Rocks are made of minerals.
3) a) Cells related to hair divide fastest.
4) The 2014 Nobel Prize in Physics was awarded for creating blue LEDs.
5) Ganymede is a moon of Jupiter, and is the largest moon in our solar system.

7) What are the two upper chambers of the heart called?
8) Which of these clouds forms highest? Is it a) cumulus, b) cirrus or c) stratus?
9) The 2014 Nobel Prize in Physiology or Medicine was awarded for discovering brain cells that do what?
10) Have people ever walked on Mars?
6) Albert Einstein said “Imagination is more important than knowledge”.
7) The two upper chambers of the heart are called atria. There’s the right atrium and the left atrium.
8) a) Cirrus clouds form higher than cumulus or stratus clouds.
9) The 2014 Nobel Prize in Physiology or Medicine was awarded for discovering cells that create a positioning system in the brain that allows us to know where we are.
10) No, people have never walked on Mars. Instead, we explore it with robots such as Curiosity.

11) If molten rock erupts from volcanoes, what comes out of a cryovolcano?
12) How many sides does a nonagon have?
13) What is a circadian rhythm? Is it a) a loud thudding of the heart, b) a sound made by cicadas, or c) a biological process that follows a 24 hour cycle?
14) What is a turtle’s plastron?
15) True or false? Baleen, the filter-feeder system in whales, is made mostly of the same protein that makes up the shells of crustaceans.
11)Volatile materials such as water or methane come out of a cryovolcano.
12) A nonagon is a nine-sided polygon.
13) c) A circadian rhythm is a biological process that follows a 24 hour cycle.
14) A turtle’s plastron is the shell covering its entire underside.
15) False. The baleen in whales is made up mostly of the protein keratin, while the shell of crustaceans is mostly made of the protein chitin.
