Quiz Answer Key and Fun Facts

1. What is the name of the invisible line that runs right around the Earth's middle, dividing it into two halves?

Answer: The Equator

The Equator divides the Earth exactly in half! The top half is called the Northern Hemisphere and the bottom half is called the Southern Hemisphere.

2. What is the name of the organ in our bodies that pumps blood?

Answer: Heart

The heart pumps blood around our bodies for us. If you put your hand to your chest, you can feel your heart going "thud-thud" - the "thud-thud" sound is your heart pumping blood.

3. What is the name of the gas in the air that keeps us alive?

Answer: Oxygen

The oxygen in air is absorbed in our lungs and keeps us alive. The air we breathe contains lots of different gases such as nitrogen. Less than a quarter of the air around us is oxygen, but that's all we need!

4. What happens if you melt something?

Answer: It changes from a solid to a liquid

When you melt something, it changes from a solid into a liquid. You can look at this by watching an ice cube melt. If you put an ice cube on the sink, it will slowly change from a solid little block of ice into a puddle of water as it melts.

5. Which of these living things does NOT have a backbone?

Answer: Earthworm

An earthworm is one of a number of animals that don't have backbones (spines). Animals without backbones are called invertebrates.

6. If the moon is full, what shape is it in the sky?

Answer: Circle

When the moon is full, it looks like a circle in the sky. The moon shines and looks bright at night because light from the sun is bouncing off its surface.

7. If I dissolve some sugar in water, what have I made?

Answer: A solution

When you dissolve something in something else, it is called making a solution. A cup of tea is a solution too, but I need some tea-leaves to make that as well as sugar!

8. Planet Earth is the ______ planet from the Sun.

Answer: third

The Earth is almost 150 million kilometres from the sun! This is just the right distance - any closer, and it would be too hot for us; any further away, and it would be too cold.

9. Which of these is the hottest?

Answer: The Sun

The surface of the sun is very, very hot - about 6000 degrees Centigrade (almost 11000 F)! A campfire and heaters are much cooler in comparison. A campfire's temperature is about 200 degrees Centigrade (400 F).

10. What is lightning made of?

Answer: Electricity

Lightning is made of electricity. It is thought that 100 lightning hits happen all over earth every single second!
