#1. True or false? Snailfish are the only fish to have shells.

#2. True or false? The tallest human who ever lived was just over 3 metres tall.

True! Cows have 11 major blood groups, but each group has lots of subtypes.
#4. What kind of object is the Sun?
The Sun is a star! Stars produce their own energy through nuclear fusion.
#5. About how many marsupial species live in Australia?
There are about 330 marsupial species in the world today and over half (or about 175 species) live in Australia.
#6. True or false? All plants have flowers.
False! there are lots of plants that don’t have flowers, including conifers (like pine trees), ferns, and mosses.
#7. CSIRO’s Kennaook/Cape Grim air pollution station collects some of the cleanest air in the world. In which state would you find it?
Kennaook/Cape Grim is on the west coast of Tasmania, and it collects air coming from the Southern Ocean.
#8. What disease did pirates often get because they didn’t eat enough fruit?
Scurvy is caused by a lack of vitamin C, a nutrient critical to the body’s tissues, immune system and blood cells. Vitamin C is found in fruit, especially citrus, strawberries, and even capsicum! Make sure you get enough in your diet to avoid the fate of many a pirate.
#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.
#10. 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.
