Congratulations! You’re a real science whiz!
Oh dear! Better brush up before the next quiz.
#1. In 1991, the volcano on Mount Pinatubo in the Philippines erupted and blasted lots of ash into the atmosphere, which scattered and absorbed incoming sunlight and cooled the Earth down. Approximately how many degrees did this eruption cool global temperatures?
The Mount Pinatubo eruption was one of the greatest volcanic eruptions in recent human history. The aerosols it spewed into the atmosphere cooled down the Earth by about 0.5 degrees Celsius for 2 years after the eruption.
#2. Which of the following types of clocks is the most accurate at keeping time?
All the most accurate clocks in the world are atomic. It’s hard to work out exactly which one is the best because they’re found all around the world, and there’s no good way to send clock signals to compare them with.
#3. Sea mice live on the ocean floor, they grow to around 15 centimetres long and 7 centimetres wide, and they don’t have eyes. What kind of animal is a sea mouse?
Sea mice are actually wide segmented worms! They got their name from their mouse-like appearance as they are brown, bronze, black or yellow in colour and are covered in hair-like setae. Their outer bristles are iridescent, which means they shine blue, green and gold under light.
#4. The Great Barrier Reef is the world’s biggest continuous living structure. About how long does the Great Barrier Reef stretch?
Located in the Coral Sea just off the coast of Queensland, the Great Barrier Reef stretches over 2,300 kilometres and takes up an area of about 344,400 square kilometres.
#5. Which of the following astronomy books is the oldest?
Physica by Aristotle was written around 330 BCE. Aristotle got a lot of things wrong, but his logical way of looking at the world paved the way for modern science.
#6. Which of the following is NOT found in human blood?
Green blood cells. Red blood cells carry oxygen, white blood cells form the immune system, and platelets create clots at injury sites, so you don’t lose too much blood.
#7. Giraffes are the tallest living land animals on Earth. How many neck bones do they have?
Even though giraffes have necks up to 2.5 metres long, they have the same number of neck bones as humans, 7! The giraffes just have really tall neck bones. Interestingly, long-necked dinosaurs had up to 19 neck bones.
#8. True or false? Proposed in 1985, the Turing Test tests whether an AI can beat humans at a collection of games and puzzles.
False. Also called the Imitation Game, the Turing Test assesses AI intelligence by the way it carries on a conversation over text. If a human cannot tell that they are talking to a machine, then the AI passes the Turing Test.
#9. What’s the main reason that plants have flowers?
Flowers are the reproductive organs of a plant. They ensure that pollen reaches the flower’s ovary (usually in the base of the flower) where seeds will start to develop.
#10. About how many websites currently exist on the web?
As of 2023, there are about 1,100,000,000 websites on the internet! But 82% of these websites are inactive, meaning only about 200 million websites are actively maintained and visited.
