#1. Helium is a noble gas, true or false?
Helium is one of the six naturally occurring noble gases, along with neon, argon, krypton, xenon, and radon. They’re all known for being odourless, colourless, and relatively non-reactive.
#2. In which month is Earth closest to the Sun?
Earth is closest to the Sun in January. It’s about five million kilometres closer than in July, which might seem like a long way, but it’s only a fraction of the average 150 million kilometres to the Sun.
#3. True or false? All marsupials are native to Australia
False. Some marsupials are native to New Guinea and not Australia, and others, including opossums, are native to the Americas.
#4. When weighing mosquitoes, how many do you need to make a gram?
Mosquitoes typically weigh about 5 milligrams each, so it takes about 200 to make a gram.
#5. Ignoring the ankle and foot, how many bones are there in a typical human leg?
There is one thigh bone (femur), a shin bone (tibia) and a bone running behind it called the fibula or calf bone, and a kneecap (patella).
#6. What is the name of the heaviest element known to occur in nature?
Uranium is the heaviest naturally occurring element.
#7. How many hearts does an octopus have?
Octopuses have three hearts – one to pump blood around the body, and one each for its two gills.
#8. If you were on Earth 350 million years ago, how many days were in a year then?
Earth used to spin faster than it does now. That means there were more rotations in a year, which means more days in a year!
#9. How fast is the speed of sound in air?
The speed of sound is roughly 1235 kilometres per hour at sea level, depending on the temperature. It tends to be slower higher up due to cooler temperatures.
#10. What is a trilobite?
Trilobites were animals that lived in the ocean and looked a bit like slaters or woodlice. They went extinct about 250 million years ago.
