Well done! You’re a real science whiz!
Oh dear! better brush up before the next quiz!
#1. Which of the following is a downside of polymer banknotes?
Polymer banknotes are harder to fold compared to paper money. But that trade-off comes with lots of benefits. Polymer banknotes are waterproof and can’t be easily ripped. Polymer banknotes last at least 2.5 times longer than paper and they more recyclable than paper banknotes.
#2. What bird lays the largest egg?
Ostriches are the largest living bird and they lay eggs that regularly weigh 1,500 grams – about 30 times a standard chicken egg! The kiwi is much smaller, but it lays eggs that weigh 370 grams. That’s nearly 15% of its body weight! In comparison, the ostrich egg is only 2% of an ostrich’s body weight.
#3. True or false? Albert Einstein’s theories predict that your head ages faster than your feet.
True! Einstein’s theory of relativity predicts that gravity’s pull slows time down. So the further away you (or your body parts) are from the Earth, the faster time goes. The effect is incredibly small but satellites orbiting far above the Earth have to take this time difference into account.
#4. You can find magnets in which of the following technologies?
Large hard drives are made of trillions of tiny magnets, and information is stored by pointing them in different directions. Electric motors use electromagnets to push and pull to make things spin. Medical imaging such as Magnetic Resonance Imaging (MRI) uses super powerful magnets and radio waves to construct a detailed picture of your body.
#5. What type of diet does an axolotl have?
Carnivorous. Axolotls mostly eat insects, worms, small fish, crustaceans, and sometimes they even nibble on other axolotls!
#6. Which of the following pieces of hardware help protect your digital files?
USB security keys are computer chips that are specially designed to hold passwords and be tamper resistant. Biometric scanners are also hardware that use your body as a type of password. Last but not least, your house’s locks physically protect your devices!
#7. Humans depend on freshwater as a basic requirement for life. What percentage of Earth’s water is freshwater?
Most of Earth’s water (96.5%) is seawater. Most of the freshwater on Earth is locked up in the ice sheets across Antarctica. Lakes only make up 0.007% of all water on Earth!
#8. True or false? If solid water is dropped into liquid water, the solid water sinks to the bottom.
False. Ice floats! It happens with big icebergs in lakes and oceans, and with little ice cubes in a refreshing glass of water.
#9. True or false? Cleopatra VII, famous ancient Egyptian Queen, also invented a treatment for baldness.
False. Historians found a recipe for a baldness cure written by a Cleopatra. But it uses weight measurements that were invented after Queen Cleopatra died!
#10. Which of the following square facts is untrue?
Squares are kites because you can fold it in half perfectly along a diagonal. They are rhombuses because all their sides are equal, and they are parallelograms because they have two pairs of parallel sides. Trapezoids have no parallel sides, so squares can’t be trapezoids.
In the USA, they call trapeziums trapezoids, and they call trapezoids trapeziums. Very confusing!
