Science Quiz Questions For Kids With Answers
General Knowledge is the awareness of a broad range of facts about various subjects, such as important events, people, history, geography, scientific phenomena, mathematical facts, etc. It is accumulated over time and is supported by human memory.
The following Science Quiz Questions for kids are based on science, Space, chemical, and energy. These Science quizzes will help students and parents revise important topics.
Science Quiz Questions For Kids With Answers
1. What is the Universe made of?
The Universe combines three types of substance: Normal Matter, Dark Matter, and Dark Energy. Normal matter covered atoms that makeup stars, planets, human beings, and every other visible object in the Universe. Dark matter is made from particles that do not absorb, reflect, or emit light, so it is not easy to detect by observing electromagnetic radiation. And Dark energy is an unknown form of energy that allows to expand Universe very quickly over time, rather than slow down.
2. Which element is highest in universe?
The majority of elements in the universe are gases. The first three most abundant elements in the universe are hydrogen, helium, and oxygen. Two types of planets exist terrestrial, made of metals and rocky like Earth, and Jovian, which are gaseous.
3. Which is the lightest gas in the world?
Hydrogen is the lightest gas and element and is the most abundant in the universe.
4. Who has the largest lithium deposits?
With 8 million tons, Chile has the world’s largest known lithium reserves. That puts the South American country ahead of Australia (2.7 million tons), Argentina (2 million tons), and China (1 million tons). Within Europe, Portugal has smaller quantities of valuable raw material.
5. What’s the lightest metal on earth?
Magnesium is the lightest metallic element and abundantly available in the earth’s crust and seawater. As a result, magnesium is the third most commonly used structural metal, following steel and aluminum.
6. Which is safer hydrogen or helium?
Helium is safer than Hydrogen. That is because helium and Hydrogen are both lighter than air. But Hydrogen is highly inflammable and incredibly dangerous. On the other hand, helium atoms are bigger and diffuse less rapidly through a balloon, and they won’t burn or react in any way.
7. What is the heaviest metal?
Osmium is the world’s heaviest material on earth, weighing twice as much as lead per teaspoon. It is a chemical element in the platinum group metals, basically it used as alloys in electrical contacts and fountain pen nibs.
8. Which metal is less dense than water?
Lithium, Sodium, and Potassium are less dense than water, so they can easily float on the water’s surface. As a result, the metals move about the water’s surface, and fizz as hydrogen gas is produced.
9. Which country has the largest copper reserves in the world?
By far, Chile, the world’s leading copper producer, produced an estimated 5.7 million metric tons of copper in 2020. In second place is Peru, with an estimated copper mine production of 2.2 million metric tons in the same year.
10. How many dimensions can humans see?
We are 3D creatures living in a 3D world, but our eyes can show us only two dimensions.
11. What’s the smallest thing in the universe?
Quarks, the smallest particles in the universe, are far smaller and operate at much higher energy levels than the protons and neutrons in which they are found.
12. What is the smallest thing we can see with our eyes?
The smallest thing that we can see with a ‘light’ microscope is about 500 nanometers. A nanometer is one billionth of a meter. So the smallest thing that you can see with a light microscope is about 200 times smaller than a hair’s width. Bacteria are about 1000 nanometers in size.
13. Which of these chemical elements is heavier than iron?
A large number of metals is heavier than iron. These include gold, lead, mercury, uranium, plutonium, molybdenum, osmium etc.
14. What is the most heavy element?
The heaviest naturally stable element is uranium, but physicists have used accelerators to synthesize larger, heavier elements over the years. For example, in 2006, physicists in the United States and Russia created element 118.
15. What are the 4 types of fossil fuels?
Petroleum, coal, natural gas and Orimulsion are the four fossil fuel types.
16. What are Four natural sources of energy?
There are four types of natural sources of energy: Solar Energy, geothermal energy, wind energy, and hydropower energy from flowing water.
17. What is the biggest source of energy?
Solar radiation is the biggest source of energy on Earth’s surface.
