Congratulations! You’re a real science whiz!
Oh dear! Better brush up before the next quiz.
#1. If you have a one-metre-tall wheel and you roll it one full rotation, how far does it travel?
The wheel would roll exactly π metres, which is about 3.1.
#2. The human body has many cool abilities. Which of the following body parts can regrow itself?
The liver is one of the special body parts in humans that can regrow itself after damage, unless it is diseased.
#3. According to plant scientists, which of the following grocery items is NOT a fruit?
Having seeds is a dead giveaway for fruits. Capsicum are full of seeds, oranges have seeds, and mangos have one big seed in the middle. Carrots are plant roots, not fruits.
#4. Which of the following animals can live forever?
Unless eaten by predators or killed by other things, the immortal jellyfish can infinitely return to an earlier stage of their life cycle and live forever!
#5. What’s the coldest temperature recorded on Mercury, the closest planet to the Sun?
Although Mercury gets very hot on its sunward side, the far side is quite cool. But the coldest parts of Mercury are deep craters near the poles that never, ever get any sunlight.
#6. Where else in the world can you find marsupials?
While most marsupials live in Australia and nearby New Guinea, about 30% of species can be found in the Americas, including one species, the Virginia opossum, in North America.
#7. We are really lucky that Earth can host life. Which of the following solar system characteristics contributed to Earth’s habitability?
We’re just the right distance from our Sun to have liquid water on the surface, orbiting in the ‘Goldilocks zone’. Jupiter’s gravity helps to deflect asteroids away from Earth, and our location in the Milky Way avoids heavy radiation from the galactic centre.
#8. True or false: if you put a sea sponge through a blender and blitzed it into cells, its cells can still recombine to form a new sea sponge.
While some animals can regenerate certain body parts, sea sponges are a rock star when it comes to this. If their individual cells are not damaged by the blending process, sea sponge cells will be able to reconnect with each other and regroup into a brand-new sponge.
#9. 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.
#10. Scientists often have fun naming their discoveries after famous people. Which celebrities have an insect named after them and why?
All of these celebrities have insects named after them. Donald Trump has a moth (Neopalpa donaldtrumpi), Kate Winslet has a beetle (Agra katewinsletae), Beyoncé has a fly (Scaptia beyonceae)
