#1. 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.
#2. How many legs does a dragonfly have?
Dragonflies are insects, so they have six legs.
#3. Which direction is Australia moving?
Australia is drifting north at about seven centimetres per year.
#4. What kind of radiation is detected by ‘The Dish’ at CSIRO’s Parkes Observatory?
The Parkes Radio Telescope has a 64-metre dish designed to pick up radio waves from space.
#5. Why does plutonium have the symbol Pu and not Pl?
Glenn Seaborg (one of the discoverers of plutonium) used the symbol Pu rather than Pl because, when said out loud, it sounds like “PEE-YEW”, which is what a child might say when something smells bad!
