ANSWERS:
Round one: chemistry
1. Water. According to UNESCO each person needs 20-50 litres of water each day to ensure
their basic needs are met. How much do you use?
2. Vinegar. The acetic acid deactivates the box jellyfish’s nematocysts (needle-like stingers). This
prevents the stingers from discharging their poison into the bloodstream.
3. Bohrium, copernicium, curium, einsteinium, fermium, lawrencium, meitnernium, mendelevium,nobelium, roentgenium, rutherfordium, seaborgium.
4. It was sold in small bottles to treat lice. These days over four billion tonnes are producedannually for fuel. While it is not possible to produce enough plant-based oil to significantlyreduce this amount, CSIRO scientists and international delegates have met in Cairns todiscuss how plant oil could be better served to reduce oil use in producing products such aslubricants, plastics and polymers.
5. Sodium.

1. The point around which two bodies orbit. The barycentre of the Earth and Moon is
approximately 1,700 kilometres below the Earth’s surface, which makes the Moon appear toorbit around the Earth.
2. (d) The ISS travels at approximately 27,724 kilometres per hour, completing about 15.7 orbitsper day. That’s one fast spacewalk!
3. (a) Given the moon is moving away from the Earth at a rate of 3.8 cm a year, its orbit is slowlyincreasing in size.
4. Mars (the volcano is called Olympus Mons).
5. Venus and Mercury.
Round three: animals
1. The ears. The elephant’s highly vascular ears allow blood to circulate close to the surface,cooling it as its ears flap in the breeze. Whodatrunk it?
2. Colourless and transparent. It looks white because of the way the inner surface of the hairsreflect light.
3. Wave its large claw furiously. The faster the wave, the more attractive it appears.

9. Don’t let those big eyes fool you! The answer is hearing.
10. Although commonly referred to as killer whales, orcas are actually part of the dolphin
(Delphinidae) family. Killer whales were spotted lurking in the southern ocean by CSIRO
statisticians working with the Australian Antarctic Division as they conducted aerial surveys ofwhale populations.
Bonus question: 11. (b) Bees regurgitate nectar several times, often as a group, to produce honey.Yum! Honey isn’t the only thing they produce - they also make silk. CSIRO scientists have usedhoneybee silk to leap one step closer to being the first to artificially produce insect silk. They havemanaged to draw out strands of honeybee silk from a ‘soup’ of proteins produced with the help of E.coli bacteria.

Answers are at the bottom:
1. San Jose State University scientist Natalie Batalha led NASA’s Kepler satellite team to discover a rocky, Earth-sized planet outside our solar system. It glows with scorching temperatures, has no water and has clouds that appear to be toxic melted silicon. It is about 1.5 times the Earth’s diameter and almost five times as massive.

their basic needs are met. How much do you use?
2. Vinegar. The acetic acid deactivates the box jellyfish’s nematocysts (needle-like stingers). This
prevents the stingers from discharging their poison into the bloodstream.
