Oh dear! Better brush up before the next quiz.

#1. Which of the following orca facts is actually a myth?

In the wild, orcas don’t usually attack humans and in some instances have been known to protect human divers from other threats. Recently, a small group of orcas have been attacking sailing ships off the coast of Spain. Experts think that one orca got hurt by a boat and has been teaching other orcas to attack boat rudders.

#2. PARO is a special robot in the shape of an animal, and it helps people to relax and feel better. Do you know which animal PARO looks like?

#3. On 29 November 1967, Australia launched the first Australian-made orbiting satellite. Where did this take place?

The first Australian orbiting satellite, the Weapons Research Establishment Satellite (WRESAT), was launched from Woomera in South Australia.

#4. Which pie filling is a member of the rose family?

All of these fruits are members of the Rosaceae family.

#5. True or false: if you put a sea sponge through a blender and blitzed it into cells, its cells can still recombine to form a new sea sponge.

While some animals can regenerate certain body parts, sea sponges are a rock star when it comes to this. If their individual cells are not damaged by the blending process, sea sponge cells will be able to reconnect with each other and regroup into a brand-new sponge.

#6. Nutritionists classify 3 main types of nutrients that provide energy to our bodies, also called macronutrients. Which of the following is NOT a macronutrient?

Your body gets its energy from fats, carbohydrates, and proteins, which you might recognise from food labels. Fibre is mostly made of carbohydrates too, but the molecules are too large for your body to digest.

#7. True or false? Orcas are classified as dolphins.

True. Orcas are part of the Delphinidae family, also known as the oceanic dolphins. This family includes the bottlenose dolphins. Orcas are the largest member of the family, weighing 10 metric tons.

#8. Which place is colder: the Arctic (the North Pole) or Antarctica (the South Pole)?

Antarctica is a lot colder than the Arctic. There are many reasons – most of Antarctica is at least 2,500 metres high, higher than Mount Kosciusko. The Arctic is also warmed by the ocean underneath it, while Antarctica is on a continent.

#9. Which of the following animals pollinate flowers?

Flowers have evolved lots ways to attract pollinators. Bee orchid flowers mimic the shape of female bees to attract male bees. Banksia flowers provide pygmy possums with a food source of pollen. Morning glory flowers even attract slugs – a rare ability!

#10. Why did Mars lose most of its atmosphere?

Mars used to have a strong magnetic field like Earth, which protects the atmosphere from the intense solar wind ejected by the Sun. When the strong magnetic field stopped working, Mars’s atmosphere got stripped away by the solar wind.
