#1. Which of the following pets is NOT a rodent?
Rats, mice and guinea pigs are all rodents, and they mostly eat plants. Ferrets are carnivores, just like cats and dogs, so they are not rodents.
#2. 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.
#3. 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.

The liver is one of the special body parts in humans that can regrow itself after damage, unless it is diseased.
#5. About 250 million years ago, Earth’s continents were all joined together into one supercontinent. What do we call that supercontinent?
Pangaea is the name for our most recent supercontinent, which broke up into 2 parts – Laurasia and Gondwanaland.
#6. Where can you find the smallest bone in our body?
The smallest bone in the human body is called the stapes, located inside the ear.
#7. What plant-based ingredient gives a book’s page its strength?
Cellulose is a complex carbohydrate commonly found around the cells of plants, such as wood, straw, and bamboo. The cellulose from these plants are used to make book pages.
#8. The Great Barrier Reef is built by billions of tiny organisms called coral polyps. Coral polyps belong to which group of living things?
Coral are marine invertebrates, meaning they are sea animals that don’t have a backbone. They are closely related to sea anemones and are in the same large group (phylum) as jellyfish.
#9. What part of your eye senses colour?
The retina is where all your light-sensing nerves are, including the colour-sensing ones. The eyelid just covers the eye. The iris is the colourful part of your eye but it does not sense colour.
