Quiz Answer Key and Fun Facts

1. Which is the gas which is essential for our life?

Answer: Oxygen

Oxygen is needed by our body to live. It is a constituent of water, which is essential for biochemical reactions. Oxygen is also needed to combine with food and release energy.

2. Which is the substance that makes the leaves of trees green?

Answer: Chlorophyll

Plants make the energy they need using carbon dioxide and water in the presence of sunlight using chlorophyll. This process is called photosynthesis.

3. What kind of rock is pumice?

Answer: Igneous

An igneous rock is a kind of rock is formed by the solidifying of molten lava from volcano. Granite is another igneous rock. Pumice is formed by lava with pores (holes) in it.

4. Into which of the categories below do duck-billed platypuses fall?

Answer: mammals

The duck-billed platypus, although a mammal, lays eggs! It is also known as a monotreme - an egg-laying mammal. Spiny anteaters are also monotremes.

5. Who formalised the law of gravity?

Answer: Sir Isaac Newton

Gravity is the force which prevents things from floating and going up and this force pulls things down. It is believed that Newton discovered gravity when an apple fell on his head!

6. Which of the following substances is NOT a compound?

Answer: Steel

Steel is an alloy, which is a mixture. It contains iron with small amounts of carbon and manganese. A molecule of water contains two atoms of hydrogen and one atom of oxygen, which react to form a compound. But the constituents of a mixture do not react. A molecule of methane contains one atom of carbon and four atoms of hydrogen.

7. Which of these animals is NOT a herbivore?

Answer: frog

Herbivores are those organisms which feed directly on plants. Carnivores eat meat by feeding on other animals. Frogs eat insects, therefore, it is a carnivore.

8. Which of these changes is a chemical change?

Answer: slaking of lime

A chemical change is a permanent irreversible change which cannot be changed by reversing the conditions and where new substances are formed. A physical change is a temporary reversible change which can be changed by reversing the conditions and where no new substances are formed. Once lime is slaked, it cannot be changed back to its original form by reversing the conditions, so it is a chemical change.

9. Who discovered the ABO blood groups?

Answer: Karl Landsteiner

Karl Landsteiner discovered that if blood from different groups is mixed, the haemoglobin present in blood gets destroyed. He was given the Nobel Prize for Medicine for this.

10. Which is the substance which makes some people have a darker complexion than others?

Answer: Melanin

More exposure to sunlight makes some glands present inside the skin release melanin. The release of more melanin makes the skin darker.
