Congratulations! You’re a real science whiz!
Oh dear! Better brush up before the next quiz.
#1. What kind of object is the Sun?
The Sun is a star! Stars produce their own energy through nuclear fusion.
#2. Which of the following animals have green blood?
Prehensile Green Tree Skinks have green blood. This is caused by a green pigment called biliverdin (bil-uh-VER-din).
#3. Chemicals called hormones send different signals around our body. Which of the following hormones is commonly known as the sleep hormone?
Melatonin is commonly known as the sleep hormone, and it is responsible for regulating your sleep-wake cycles.
#4. Bose-Einstein condensates are sometimes known as a fifth state of matter, where particles are cooled to very cold temperatures close to absolute zero. Do you know how many degrees is absolute zero?
Theoretically, absolute zero is the temperature where particles stop moving and it’s the coldest temperature possible. The Celsius scale was changed in 1954 so that absolute zero was exactly –273.15 °C.
#5. Which of the following gases directly damages the ozone layer?
Chlorofluorocarbons, before they were banned, were used in aerosol cans and refrigeration. The chloride atoms in these gases destroyed ozone (O3) molecules.
#6. Charles Darwin is famous for developing the theory of evolution. Which of the following books did he write?
Charles Darwin’s most famous book has the long title of On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life.
#7. Which of the following spectacular events is not caused by our Sun?
Our sun powers almost all the weather on Earth, but it doesn’t power everything. Deep sea thermal vents get their heat from magma seeping up through Earth’s crust. Scientists think thermal vents might support life on moons further away from the sun, like Jupiter’s Europa.
#8. Rising sea temperatures threaten the Reef because the high temperatures stress the corals. What colour do stressed corals turn?
Healthy corals are home to colourful organisms called zooxanthellae. But when sea temperatures rise, stressed corals kick out the zooxanthellae, revealing the coral’s white colour. This process is called coral bleaching and it’s a major threat to the Reef.
#9. Which of the following human blood types is considered a “universal” blood type and can be given to everyone regardless of blood type?
Blood type O negative can be given to anyone without causing problems. In emergency situations when a patient’s blood type is not known, O negative blood is very handy!
#10. True or false? Some flowers make colours that cannot be seen by humans.
True, many pollinators (like bees) can see colours that humans can’t, such as ultraviolet colours. To attract these pollinators, many flowers have ultraviolet patterns on their petals.
