Congratulations! You’re a real science whiz!
Oh dear! Better brush up before the next quiz.
#1. What part of the flower causes allergies and hay fever?
Many plants use pollinators like bees to spread their pollen. But some plants just release pollen into the air and hope that it’ll spread to another plant!
#2. 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.
#3. Which part of an insect’s body do their legs attach to?
All 6 legs attach to the insect’s thorax.
#4. 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.
#5. True or false: the human blood is red because it contains the protein haemoglobin.
Haemoglobin is found in your red blood cells. This protein contains iron, which helps to attract oxygen molecules from the air you breathe.
#6. Before the 1300s, which of the following archaeological sites was the tallest human-made structure?
The Great Pyramid of Egypt was the tallest human-made structure from its construction in 2570 BCE (4,593 years ago) until the Lincoln Cathedral was completed in England in 1311 CE.
#7. Which country has the most forests in the world?
Russia is home to the world’s largest area of forests at 815 million hectares. That’s about 20% of the world’s forests!
#8. 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.
#9. The Great Barrier Reef is built by billions of tiny organisms called coral polyps. Coral polyps belong to which group of living things?
Coral are marine invertebrates, meaning they are sea animals that don’t have a backbone. They are closely related to sea anemones and are in the same large group (phylum) as jellyfish.
#10. The Great Barrier Reef is the world’s biggest continuous living structure. About how long does the Great Barrier Reef stretch?
Located in the Coral Sea just off the coast of Queensland, the Great Barrier Reef stretches over 2,300 kilometres and takes up an area of about 344,400 square kilometres.
